Abstract
PURPOSE OF REVIEW Congenital melanocytic nevi (CMN) and acquired nevi are prevalent in pediatric populations, with distinct characteristics and management considerations. This chapter aims to equip pediatricians with knowledge to discern between benign and high-risk nevi, facilitating appropriate referrals and management within primary care settings. Risk factors associated with malignant melanoma (MM) underscore the importance of vigilant monitoring and early referral to dermatology for suspicious lesions. RECENT FINDINGS Recent findings highlight the variability in CMN presentation and the evolving diagnostic strategies, emphasizing the need for multidisciplinary approaches to optimize patient outcomes. SUMMARY Management of CMN involves tailored surveillance and intervention strategies, with an emphasis on early identification of high-risk features for MM and neurocutaneous melanosis (NCM). Pediatricians play a crucial role in advocating for sun protection practices and facilitating timely referrals, thereby contributing to the overall well being of pediatric patients with nevi.

Abstract
Infectious etiologies have previously been proposed as causes of both melanoma and non-melanoma skin cancer. This exploratory overview explains and presents the evidence for the hypothesis that a microorganism excreted in infected ruminant animal feces, Mycobacterium avium subspecies paratuberculosis (MAP), is the cause of some cases of cutaneous melanoma (CM). Occupational, residential, and recreational contact with MAP-contaminated feces, soil, sand, and natural bodies of water may confer a higher rate of CM. Included in our hypothesis are possible reasons for the differing rates and locations of CM in persons with white versus nonwhite skin, why CM develops underneath nails and in vulvar skin, why canine melanoma is an excellent model for human melanoma, and why the Bacille Calmette-Guérin (BCG) vaccine has demonstrated efficacy in the prevention and treatment of CM. The pathogenic mechanisms and etiologic aspects of MAP, as a transmittable agent underlying CM risk, are carefully deliberated in this paper. Imbalances in gut and skin bacteria, genetic risk factors, and vaccine prevention/therapy are also discussed, while acknowledging that the evidence for a causal association between MAP exposure and CM remains circumstantial.

Abstract
While all childhood cancers are rare, tumors that are particularly infrequent or underrepresented within pediatrics are studied under the umbrella of the Children's Oncology Group Rare Tumor committee, divided into the Retinoblastoma and Infrequent Tumor subcommittees. The Infrequent Tumor subcommittee has traditionally included an emphasis on globally rare tumors such as adrenocortical carcinoma, nasopharyngeal carcinoma, or those tumors that are rare in young children, despite being common in adolescents and young adults, such as colorectal carcinoma, thyroid carcinoma, and melanoma. Pleuropulmonary blastoma, gonadal stromal tumors, pancreatic tumors including pancreatoblastoma, gastrointestinal stromal tumor, nonmelanoma skin cancers, neuroendocrine tumors, and desmoplastic small round cell tumors, as well as other carcinomas are also included under the heading of the Children's Oncology Group Rare Tumor committee. While substantial challenges exist in rare cancers, inclusion and global collaboration remain key priorities to ensure high quality research to advance care.

Abstract
Malignant melanoma (MM) is a highly aggressive form of skin cancer with increasing global incidence rates, particularly in developed countries. Variations in the prevalence and quality of care provided to patients with melanoma exist across different regions and across different sex and age. Assessing the global burden of melanoma and evaluating the quality of care can provide valuable insights for developing targeted interventions in certain underperforming regions and improving patient outcomes. This study aimed to systematically analyze the Global Burden of Disease Study from 1990 to 2019 to assess the quality of care for skin malignant melanoma on a global scale. We conducted a comprehensive literature review and extracted data on melanoma incidence, mortality, and disability-adjusted life years (DALYs) from the Global Burden of Disease Study. We incorporated these variables using principal component analysis (PCA) to form an informative single variable of quality of care index (QCI) and analyzed its spatial-temporal variations as well as disparities across age, sex and socio-demographic index (SDI). The overall Quality of Care Index (QCI) for melanoma improved from 82.81 in 1990 to 91.29 in 2019. The QCI score showed a positive correlation with socioeconomic status across regions. Australia ranked highest in QCI (99.96), while Central African Republic, and Kiribati had the lowest scores. China and Saudi Arabia showed significant QCI improvement, while the QCI of the Democratic People's Republic of Korea, Zimbabwe, and Guam decreased from 1990 to 2019. The highest QCI scores were observed in the age groups of 20-39 years old (93.40-94.65). Gender disparities narrowed globally in these three decades, but lower Socio-demographic Index (SDI) regions showed increased gender inequities. Our findings highlighted the spatial-temporal variations in the quality of care of MM as well as its disparities across different SDI levels, age groups and sex. These findings offer valuable insights and guidance for implementing focused interventions and resource allocation to enhance the quality of care and overall outcomes for MM worldwide, especially for underperforming regions.

Abstract
INTRODUCTION Pediatric melanoma is the most commonly diagnosed skin cancer in children, with the annual incidence recently increasing by an average of 2% each year. Ultraviolet (UV) radiation from excessive sun exposure is an important carcinogenic risk factor, with penetration varying greatly throughout the country. Consequently, an individual's geographic location may play a role in how much exposure to high UV index rays they receive throughout their lifetime. The objective of this study was to use the surveillance, epidemiology, and end results SEER database to study geographic trends in incidence, staging, and mortality of pediatric melanoma between 2009 and 2019 and determine their relation to UV index in the United States. MATERIALS AND METHODS A retrospective analysis of pediatric patients from 0 to 19 years in the surveillance, epidemiology, and end results 22 registries incidence database (17 states) and 17 registries incidence-based mortality database (12 states) was conducted from 2009 to 2019 based on a diagnosis of melanoma of the skin using the International Classification of Childhood Cancer codes for malignant melanoma. Data regarding patient demographics and incidence, staging, and mortality per state were extracted. Incidence data were geographically mapped and mean UV index distribution from www.epa.gov was superimposed. RESULTS Incidence of pediatric melanoma was stratified regionally, with a total of 1665 new cases from 2009 to 2019. The Northeast had 393 new cases, with 244 (62.1%) localized cases, 55 (14.0%) lymph node-invasive and metastatic (advanced) cases, and 6/146 (4.1%) cases of mortality. The Midwest had 209 new cases, with 123 (58.9%) localized cases, 29 (13.9%) advanced cases, and 1/57 (1.8%) case of mortality. The South had 487 new cases, with 224 (46.0%) localized cases, 104 (21.4%) advanced cases, and 8/232 (3.4%) cases of mortality. The West had 576 new cases, with 364 (63.2%) localized cases, 82 (14.2%) advanced cases, and 23/551 (4.2%) cases of mortality. Mean UV index was 4.4 in the Northeast, 4.8 in the Midwest, 7.3 in the South, and 5.5 in the West from 2006 to 2020. The regional difference in incidence was not statistically significant. There was a statistically significant increased number of advanced cases in the South as compared to the Northeast (P = 0.005), West (P = 0.002), and Midwest (P = 0.02), with a significant correlation coefficient of 0.7204 between advanced cases and mean UV index in the South. CONCLUSIONS There is a statistically significant increased incidence of lymph node-invasive and metastatic pediatric melanoma cases in the South as compared to the West, Northeast, and Midwest regions of the United States. There is also a significant correlation between the incidence of lymph node-invasive and metastatic pediatric melanoma cases and UV index. In the pediatric population, there is no statistically significant association between total incidence and mortality of melanoma and geographic region. There is an increased prevalence of pediatric melanoma seen in White and female patients. This suggests that an individual's geographic location in the United States during childhood may play a role in their likelihood of malignant melanoma development, advanced-stage melanoma development, and mortality.

Abstract
The current evidence on paediatric melanoma is heterogeneous, especially regarding the prognosis of different histological subtypes. We sought to systematically review the evidence on paediatric melanoma, highlighting the major sources of heterogeneity and focusing on available data on single patients. A systematic search was performed from 1948 to 25 January 2021. Only studies reporting at least one case of cutaneous melanoma in patients aged ≤18 years were included. Unknown primary and uncertain malignant melanomas were excluded. Three couples of authors independently performed title/abstract screening and two different authors reviewed all the relevant full texts. The selected articles were manually cross-checked for overlapping data for qualitative synthesis. Subsequently data on single patients were extracted to perform a patient-level meta-analysis. PROSPERO registration number: CRD42021233248. The main outcomes were melanoma-specific survival (MSS) and progression-free survival (PFS) outcomes. Separate analyses were done of cases with complete information on histologic subtype, focusing on superficial spreading (SSM), nodular (NM) and spitzoid melanomas, as well as of those classified as de-novo (DNM) and acquired or congenital nevus-associated melanomas (NAM). The qualitative synthesis covered 266 studies; however, data on single patients were available from 213 studies including 1002 patients. Among histologic subtypes, NM had a lower MSS than both SSM and spitzoid melanoma, and a lower PFS than SSM. Spitzoid melanoma had a significantly higher progression risk than SSM and trended toward lower mortality. Focusing on nevus-associated status, DNM demonstrated better MSS after progression than congenital NAM, and no differences were highlighted in PFS. Our findings describe the existence of different biological patterns in paediatric melanoma. Specifically, spitzoid melanomas demonstrated intermediate behaviour between SSM and NM and showed a high risk of nodal progression but low mortality. This raises the question of whether spitzoid lesions are being over-diagnosed as melanoma in childhood.

Abstract
Background Melanoma is a lethal skin cancer, and the risk of developing it is increased by exposure to ultraviolet (UV) radiation. The production of cytokines such as interleukin-15 (IL-15), induced by the exposure of skin cells to UV rays, could also promote melanoma development. The aim of this study is to investigate the possible role of Interleukin-15/Interleukin-15 Receptor α (IL-15/IL-15Rα) complexes in melanoma development. Methods The expression of IL-15/IL-15Rα complexes by melanoma cells was evaluated both ex vivo and in vitro by tissue microarray, PCR, and flow cytometry. The presence of the soluble complex (sIL-15/IL-15Rα) in the plasma of metastatic melanoma patients was detected using an ELISA assay. Subsequently, we investigated the impact of natural killer (NK) cell activation after rIL-2 starvation followed by exposure to the sIL-15/IL-15Rα complex. Finally, by analyzing public datasets, we studied the correlation between IL-15 and IL-15Rα expressions and melanoma stage, NK and T-cell markers, and overall survival (OS). Results Analysis of a melanoma tissue microarray shows a significant increase in the number of IL-15+ tumor cells from the benign nevi to metastatic melanoma stages. Metastatic melanoma cell lines express a phorbol-12-myristate-13-acetate (PMA)-cleavable membrane-bound IL-15 (mbIL-15), whereas cultures from primary melanomas express a PMA-resistant isoform. Further analysis revealed that 26% of metastatic patients present with consistently high plasmatic levels of sIL-15/IL-15Rα. When the recombinant soluble human IL-15/IL-15Rα complex is added to briefly starved rIL-2-expanded NK cells, these cells exhibit strongly reduced proliferation and levels of cytotoxic activity against K-562 and NALM-18 target cells. The analysis of public gene expression datasets revealed that high IL-15 and IL-15Rα intra-tumoral production correlates with the high levels of expression of CD5+ and NKp46+ (T and NK markers) and significantly correlates with a better OS in stages II and III, but not in stage IV. Conclusions Membrane-bound and secreted IL-15/IL-15Rα complexes are continuously present during progression in melanoma. It is notable that, although IL-15/IL-15Rα initially promoted the production of cytotoxic T and NK cells, at stage IV promotion of the development of anergic and dysfunctional cytotoxic NK cells was observed. In a subgroup of melanoma metastatic patients, the continuous secretion of high amounts of the soluble complex could represent a novel NK cell immune escape mechanism.

Abstract
PURPOSE To improve the diagnostic accuracy and optimal management of pediatric melanomas. METHODS We conducted a retrospective descriptive, multicenter study of the epidemiological, clinical, and dermoscopic characteristics of histopathologically proven melanomas diagnosed in patients less than 18 years old. Data on sociodemographic variables, clinical and dermoscopic characteristics, histopathology, local extension, therapy and follow-up, lymph node staging, and outcome were collected from the databases of three Italian dermatology units. We performed a clinical evaluation of the morphological characteristics of each assessed melanoma, using both classic ABCDE criteria and the modified ABCDE algorithm for pediatric melanoma to evaluate which of the two algorithms best suited our series. RESULTS The study population consisted of 39 patients with a histologically confirmed diagnosis of pediatric melanoma. Comparing classic ABCDE criteria with the modified ABCDE algorithm for pediatric melanomas, the modified pediatric ABCDE algorithm was less sensitive than the conventional criteria. Dermoscopically, the most frequent finding was the presence of irregular streaks/pseudopods (74.4%). When evaluating the total number of different suspicious dermoscopy criteria per lesion, 64.1% of the lesion assessments recognized two dermoscopic characteristics, 20.5% identified three, and 15.4% documented four or more assessments. CONCLUSIONS Contrary to what has always been described in the literature, from a clinical point of view, about 95% of our cases presented in a pigmented and non-amelanotic form, and these data must be underlined in the various prevention campaigns where pediatric melanoma is currently associated with a more frequently amelanotic form. All the pediatric melanomas analyzed presented at least two dermoscopic criteria of melanoma, suggesting that this could be a key for the dermoscopic diagnosis of suspected pediatric melanoma, making it possible to reach an early diagnosis even in this age group.

Abstract
Interferon-gamma (IFNG) has long been regarded as the flag-bearer for the anti-cancer immunosurveillance mechanisms. However, relatively recent studies have suggested a dual role of IFNG, albeit there is no direct experimental evidence for its potential pro-tumor functions. Here we provide in vivo evidence that treatment of mouse melanoma cell lines with Ifng enhances their tumorigenicity and metastasis in lung colonization allograft assays performed in immunocompetent syngeneic host mice, but not in immunocompromised host mice. We also show that this enhancement is dependent on downstream signaling via Stat1 but not Stat3, suggesting an oncogenic function of Stat1 in melanoma. The experimental results suggest that melanoma cell-specific Ifng signaling modulates the tumor microenvironment and its pro-tumorigenic effects are partially dependent on the γδ T cells, as Ifng-enhanced tumorigenesis was inhibited in the TCR-δ knockout mice. Overall, these results show that Ifng signaling may have tumor-promoting effects in melanoma by modulating the immune cell composition of the tumor microenvironment.

Abstract
BACKGROUND Malignant melanoma is rare in the pediatric population and management is largely extrapolated from adult guidelines. Adult data have shown that immediate completion lymph node dissection (CLND) does not improve overall survival in selected patients with clinically node negative, sentinel lymph node-positive disease. Current nodal management in children is unknown. METHODS The National Cancer Database (NCDB) was queried for patients with melanoma from 2012-2017 and patients categorized as pediatric (≤18 years, n=962) or adult (n=327,987). Factors associated with CLND in children with positive SLNB were evaluated in multivariable analysis. Kaplan-Meier survival analysis was performed. RESULTS Compared to adults, children present with thicker primary tumors (T3 or T4 26.5% vs 15.5%, p<0.001), resulting in higher rates of nodal assessment with SLN biopsy or LND (60.2% vs 36.6%, p<0.001) and higher rates of regional nodal disease (35.1% vs 23.4%, p<0.001). Children underwent higher rates of CLND after SLN biopsy (10.4% vs 4.1%) and upfront lymph node dissection (15.2% vs 8.7%). A decreased rate of CLND was noted in 2017 compared to 2012 (odds ratio (OR) 0.16 (p=0.005). CLND was performed more often on multivariable analysis for older pediatric age (>12 years, OR=1.6, p=0.037) and lower extremity primary (OR=0.29, p<0.001). Children with regional nodal disease have improved 3-year overall survival compared to adults (96.5% vs 71.0%, p<0.001). CONCLUSIONS Children with melanoma have higher rates of nodal disease but better survival than adults. As in adults, there has been a recent increase in close nodal observation rather than CLND for patients with positive SLN. Further study of nodal surveillance for pediatric patients is warranted.

Abstract
Children and adolescents have high rates of sunburn and high levels of ultraviolet radiation (UVR) exposure and are therefore at risk of developing skin cancer in later life. Minimizing UVR exposure in childhood and adolescence may be the most important component of skin cancer prevention efforts. Thus, age-adapted prevention campaigns, targeting children, adolescents and caregivers, are needed to change sun protection behaviour among individuals in these age groups. In the first part of this review, we describe the 'SunPass' programme, which was initiated in Germany in 2010 as the first nationwide educational intervention for sun safety designed to teach kindergarten children and their caregivers how to protect themselves from overexposure to the sun. Implemented in 55 kindergartens, this programme has been shown to be effective at improving sun protection behaviour (P < 0.001) and hat use (P = 0.029) among kindergarten children, as well as at improving shade practices and increasing demand for protective clothing (P < 0.001). Up to 40 000 children, 50 000 parents/grandparents and 2500 kindergarten caregivers took part in the SunPass programme in Germany from 2019 to June 2021. The programme has also been adapted and implemented in several other European countries and could be readily adapted for use elsewhere. In the second part of this review, we discuss the specific challenges faced by adolescents and consider how these issues may impact their sun protection behaviour. Adolescents have difficulties suppressing responses to reward-related cues and projecting themselves into the future. They also place a lot of importance on social acceptance and cosmetic appearance, and their higher risk of depression, addiction and impulsivity make them vulnerable to tanning addiction. These specificities need to be acknowledged by dermatologists, so they can adapt their therapeutic relationship and develop effective sun protection interventions for this generation.

Abstract
Aim: Assess the knowledge and behavior of Lebanese parents when it comes to melanoma and its prevention in children. Methods: A survey, to be completed by parents, was sent through children from three schools. Results: During sun exposure only 23.5% of 1012 respondents were always covering enough areas of their children's skin and 74.1% did not always apply sunscreen to their children. Parents of private school children were three times more likely to apply sunscreen to their children when exposed to sun, four times more likely to reapply sunscreen every 2–3 h and 21 times more likely to use a higher sun protection factor. Conclusion: Sun protection in children is insufficient and sunburns are frequent, illustrating the need for melanoma awareness campaigns.

Abstract
BACKGROUND The first histology-independent marketing authorisation in Europe was granted in 2019. This was the first time that a cancer treatment was approved based on a common biomarker rather than the location in the body at which the tumour originated. This research aims to explore the implications for National Institute for Health and Care Excellence appraisals. METHODS Targeted reviews were undertaken to determine the type of evidence that is likely to be available at the point of marketing authorisation and the analyses required to support National Institute for Health and Care Excellence appraisals. Several challenges were identified concerning the design and conduct of trials for histology-independent products, the greater levels of heterogeneity within the licensed population and the use of surrogate end points. We identified approaches to address these challenges by reviewing key statistical literature that focuses on the design and analysis of histology-independent trials and by undertaking a systematic review to evaluate the use of response end points as surrogate outcomes for survival end points. We developed a decision framework to help to inform approval and research policies for histology-independent products. The framework explored the uncertainties and risks associated with different approval policies, including the role of further data collection, pricing schemes and stratified decision-making. RESULTS We found that the potential for heterogeneity in treatment effects, across tumour types or other characteristics, is likely to be a central issue for National Institute for Health and Care Excellence appraisals. Bayesian hierarchical methods may serve as a useful vehicle to assess the level of heterogeneity across tumours and to estimate the pooled treatment effects for each tumour, which can inform whether or not the assumption of homogeneity is reasonable. Our review suggests that response end points may not be reliable surrogates for survival end points. However, a surrogate-based modelling approach, which captures all relevant uncertainty, may be preferable to the use of immature survival data. Several additional sources of heterogeneity were identified as presenting potential challenges to National Institute for Health and Care Excellence appraisal, including the cost of testing, baseline risk, quality of life and routine management costs. We concluded that a range of alternative approaches will be required to address different sources of heterogeneity to support National Institute for Health and Care Excellence appraisals. An exemplar case study was developed to illustrate the nature of the assessments that may be required. CONCLUSIONS Adequately designed and analysed basket studies that assess the homogeneity of outcomes and allow borrowing of information across baskets, where appropriate, are recommended. Where there is evidence of heterogeneity in treatment effects and estimates of cost-effectiveness, consideration should be given to optimised recommendations. Routine presentation of the scale of the consequences of heterogeneity and decision uncertainty may provide an important additional approach to the assessments specified in the current National Institute for Health and Care Excellence methods guide. FURTHER RESEARCH Further exploration of Bayesian hierarchical methods could help to inform decision-makers on whether or not there is sufficient evidence of homogeneity to support pooled analyses. Further research is also required to determine the appropriate basis for apportioning genomic testing costs where there are multiple targets and to address the challenges of uncontrolled Phase II studies, including the role and use of surrogate end points.

Abstract
Pediatric melanoma is a rare form of the tumor whose epidemiology is widely increasing thanks to the improvement of dermoscopic and anatomopathologic diagnostic techniques. Although it is a tumor of considerable interest in adults, little has been described about the pediatric field. The objective of our study was then to identify the possible risk factors for the development of melanoma in the pediatric population. We performed a retrospective study conducted in the Melanoma and Skin Cancer Unit and Unit of Dermatology (Livorno, Italy). We analyzed a population of 38 children under 21 years with a diagnosis of melanoma. This population was compared with a control population of 114 children followed up in our dermatologic clinic. From our combined univariate-multivariate statistics analysis, the number of nevi [regression coefficient (RC) of 1.04 and odds ratio (OR) of 2.8 confidence interval (Cl, 1.2-6.6)], and family history of melanoma [RC of 1.99 and OR of 7.3 (Cl, 2.3-22.7)] emerged as possible risk factors for the development of melanoma. The identification of these elements would allow the physician to carry out a more targeted preliminary assessment of the patient, potentially decisive in cases of diagnostic doubt of the lesion. Our study also lays the foundations for identifying those children who, despite not having received a diagnosis of melanoma on histologic examination, should be considered as patients susceptible to a focused follow-up, because of the presence of the risk factors that emerged from our research.

Abstract
Melanoma is rare in pediatric patients and even more so in those with darker Fitzpatrick skin types. Although risk factors for conventional melanoma are similar in both adult and pediatric cases, the presentation of melanoma in pediatric patients is often distinct from adults. Here, we describe a case of amelanotic ulcerated nodular melanoma with regional lymph node metastases treated with nivolumab in a patient with Fitzpatrick skin type VI.

Abstract
BACKGROUND A polygenic inheritance involving high, medium and low penetrance genes has been suggested for melanoma susceptibility in adults, but genetic information is scarce for paediatric patients. OBJECTIVE We aim to analyse the major high and intermediate melanoma risk genes, CDKN2A, CDK4, POT1, MITF and MC1R, in a large multicentre cohort of Italian children and adolescents in order to explore the genetic context of paediatric melanoma and to reveal potential differences in heritability between children and adolescents. METHODS One-hundred-twenty-three patients (<21 years) from nine Italian centres were analysed for the CDKN2A, CDK4, POT1, MITF, and MC1R melanoma predisposing genes. The rate of gene variants was compared between sporadic, familial and multiple melanoma patients and between children and adolescents, and their association with clinico-pathological characteristics was evaluated. RESULTS Most patients carried MC1R variants (67%), while CDKN2A pathogenic variants were found in 9% of the cases, the MITF E318K in 2% of patients and none carried CDK4 or the POT1 S270N pathogenic variant. Sporadic melanoma patients significantly differed from familial and multiple cases for the young age at diagnosis, infrequent red hair colour, low number of nevi, low frequency of CDKN2A pathogenic variants and of the MC1R R160W variant. Melanoma in children (≤12 years) had more frequently spitzoid histotype, were located on the head/neck and upper limbs and had higher Breslow thickness. The MC1R V92M variant was more common in children than in adolescents. CDKN2A common polymorphisms and MC1R variants were associated with a high number of nevi. CONCLUSION Our results confirm the scarce involvement of the major high-risk susceptibility genes in paediatric melanoma and suggest the implication of MC1R gene variants especially in the children population.

Abstract
BACKGROUND/OBJECTIVE Relative to adults, rates of melanoma are lower in children. Due to its rarity, it is difficult to assess the incidence, trends, and outcomes of this malignancy. Much of our understanding comes from single institution or regional cancer registries which may not be large enough to detect subtleties in the burden of pediatric melanoma. METHODS Data from the 2004 to 2016 National Cancer Database were analyzed; this database captures approximately 70% of all cancer diagnoses in the United States. RESULTS Our analysis consisted of 1903 cases. A majority were White (89.8%), the mean age was 12.4 years, and the ratio of females: males was 1.2:1.0. The most common anatomic location was the trunk (31.1%). Between 2004 and 2016, a decreasing trend in the number of new melanoma cases was observed. Comparing histologic subtype by age, there was an increased percentage of nodular and epithelioid and spindle cell tumors in the pre-teen children and a greater percentage of superficial spreading tumors in teenagers. Overall, a majority of cases were stage 0 or I (56.9%), with relatively few stage IV cases (2.0%). A 5-year all-cause survival of greater than 90% was observed for stage I-III tumors, with stage IV tumors having a 5-year all-cause survival of 34.4%. CONCLUSION Comparable to previous studies, pediatric melanoma occurred most often in Whites, females, and adolescents. However, we detected a decreasing trend in new cases, noted differences between histologic subtype and age, and observed a 5-year all-cause survival rate of greater than 90% for stage I-III tumors.

Abstract
The dermoscopic features of longitudinally aligned pigmentation on the hyponychium were previously described in pediatric patients with longitudinal melanonychia. We report four cases of biopsy-proven acral melanocytic nevi on the hyponychium with a longitudinal brush pigmentation (LBP) pattern in dermoscopy. This LBP pattern on the hyponychium may be a counterpart of the fibrillar pattern of acral melanocytic nevi. Therefore, the LBP pattern in dermoscopy may provide a useful clue for distinguishing benign melanocytic nevi from melanoma in pediatric patients.

Abstract
Age plays a dynamic role in incidence, presentation, and extent of disease for cutaneous melanoma. Even within the spectrum of juvenile melanoma, there exists a range of spitzoid and nonspitzoid melanocytic and melanoma lesions. Spitzoid melanomas, a more favorable disease in juvenile patients, are malignant lesions and require treatment as such. Lymph node metastases in melanoma occur at lower rates in older patients compared with younger counterparts, yet the rate of metastases is still high. Age appears to play an important role in the development and progression of melanoma, and understanding the differences across age populations is important when counseling patients.

Abstract
BACKGROUND Malignant melanoma (MM) arises predominantly after adolescence and is uncommon in children. Congenital MM in newborns is even rarer with a dearth of published literature; as a consequence, there is no uniform standard for the pathogenesis and treatment for neonatal malignant melanoma. Herein we report a case of giant congenital nodular MM in a newborn, including its clinical, imaging, pathological and molecular pathological features. This case is the largest giant congenital primary nodular malignant melanoma in utero in neonates currently reported in China. CASE PRESENTATION A female neonatal patient was found to have a 2.97 cm× 1.82 cm×1.50 cm mass with a clear boundary at the right acromion in color Doppler ultrasound examination at 24 weeks of gestation. The mass increased to 3.0 cm×5.0 cm×9.0 cm at birth, and local ulceration was seen. MRI demonstrated that the mass was located on the right shoulder and underarm in a lobulated appearance, and surrounded the right scapula which was deformed. Clinical stage:IV(AJCC 8th Edition (2017)). α-Fetoprofein (AFP) by hematological examination: 1210ng/ml, NSE: 21.28ng/ml, LDH: 842U/L. The patient underwent surgical resection of the tumor, and was pathologically diagnosed as neonatal congenital malignant melanoma; immunohistochemistry (IHC): S-100 (+), HMB45 (+), Melan A (+), and Tyrosinase (+). Molecular pathological examination for BRAF V600E showed no mutations (Quantitative Real-time PCR, qPCR); And so were NRAS, C-kit (exons 9,11,13,14,17,18), and TERT (promoter locus, C228T and C250T) (Sanger sequencing). Non-surgical therapies were not carried out after the surgical resection of the tumor. After 6 months of follow-up, the child developed normally, and color Doppler ultrasound showed no obvious tumor growth or abnormality in the original tumor site. CONCLUSIONS It is extremely rare to see giant congenital primary nodular MM in utero in neonates. The pathogenesis, treatment and prognosis of congenital MM need further research. The diagnosis mainly depends on histopathology and immunohistochemistry, and it needs to be differentiated from malignant lymphoma and primitive neuroectodermal tumor. The current treatment strategy for MM relies on the surgical excision of the mass. Research directed at molecular detection for genetic mutations would contribute to targeted therapy and better prognosis.

Abstract
Melanoma is the most common skin cancer in children, often presenting in an atypical fashion. The incidence of melanoma in children has been declining. The mainstay of therapy is surgical resection. Sentinel lymph node biopsy often is indicated to guide therapy and determine prognosis. Completion lymph node dissection is recommended in selective cases after positive sentinel lymph node biopsy. Those with advanced disease receive adjuvant systemic treatment. Because children are excluded from melanoma clinical trials, management is based on pediatric retrospective data and adult clinical trials. This review focuses on epidemiology, presentation, surgical management, adjuvant therapy, and outcomes of pediatric melanoma.

Abstract
Background: Malignant melanoma is the most serious type of skin cancer, and its incidence rate increases with age. Malignant melanoma in infants has been rarely reported in the literature. Herein, we report a case of malignant transformation of a nodular lesion found in the penis of a patient with a giant congenital nevus. Case presentation: A 1-month-old male patient was admitted due to the presence of a giant congenital nevus involving the lower abdomen, bilateral inguinal areas, genitals, and left thigh and knee. Six months later, nodules measuring 1 cm in diameter protruding from the genital area were noted, and a part of the nodule was removed via elliptical excision with the patient under general anesthesia. Gross examination showed an edematous lesion similar to a neurofibroma and with unclear boundaries. Biopsy revealed a malignant melanoma, with a Breslow thickness of at least 3 mm, and absence of lymphovascular invasion; the biopsy confirmed incomplete excision. The patient was scheduled for radical resection, but reconstruction was not performed following surgical resection due to the guardian's refusal. Hence, the patient only received an adjuvant medical treatment and eventually died. Conclusion: We reported a rare case of an infant with a malignant melanoma in the penis. Congenital malignant melanoma rarely occurs in infants; however, due to its fatal consequences, follow-up should be performed to assess for malignant changes.

OBJECTIVES to analyze the survival in juvenile melanoma. METHODS retrospective study conducted by hospital record review and cancer records of patients aged 0 to 19 years, with histologically proven melanoma and treated between 1997 and 2017 at the Erasto Gaertner Hospital in Curitiba-PR. RESULTS the sample comprised 24 patients, female (62.5%), mean 14.14 ± 4.72 years old, with head and neck melanoma (37.5%), chest (25%) and extremities. (20.8%). Signs and symptoms at diagnosis were increased lesion size (25%), bleeding (20.8%) and pruritus (16.6%). There was a Breslow II and IV index and Clark IV level, with a statistical tendency between Breslow IV and death (p = 0.127), and significance between Clark V and death (p = 0.067). Nine (37.5%) patients had metastases, six (25%) with distant metastases died (p = 0.001), five were girls (20.8%). Surgery was the standard treatment and chemotherapy the most used adjuvant (37.5%). The average time between diagnosis and death was 1.3 ± 1.2 years and survival were 3.7 ± 3.2 years. CONCLUSION there was a delay in diagnosis, high morbidity and mortality and average survival less than five years.

Abstract
The epidemiological trends of malignant melanoma have been well described in the literature. However, there remains a paucity of population-based studies assessing melanoma epidemiology in our younger patients (20 years of age or less). Other studies indicate that melanoma incidence has risen in pediatric populations over the last several decades and that these tumors may display different clinical characteristics from those arising in adult populations. We conducted a retrospective, population-based analysis of all incident cases of melanoma occurring in young patients aged ≤20 years in Alberta from 1992 to 2011. Information, including patient age, sex, anatomical location, date of diagnosis, histological subtype (if available), level of invasion, and date of death (if applicable), was obtained from the Alberta Cancer Registry. All cases occurring during a 10-year period from 1993 to 2011 have been reviewed. A total of 71 cases were diagnosed during this time (63% female and 37% male). Age range was 0-20 years (mean of 17.5 years). Truncal melanomas made up 36% of cases, while 28% occurred on the lower limbs, 17% on the upper limbs, and 18% in the head and neck region. Average Breslow thickness was 1.97 mm; 67% of tumors were less than 1 mm thick. Unfortunately, 8 of 71 patients died from their disease. Overall, the incidence of melanoma in patients aged ≤20 years appeared to decrease in Alberta in the past 20 years; however, there has been an increase in the thickness of melanoma at diagnosis, which needs to be addressed.

Abstract
Malignancies of the vulva in the pediatric population are exceptionally rare, which makes it difficult to gain any insight into their clinicopathologic profile. In this review, we summarize all published cases of a vulva malignancy in pediatric patients (≤21 years) reported in the English language literature for the 50-year period between 1970 and 2020. We estimate that less than 100 malignancies have been reported in total, approximately 50% of which were rhabdomyosarcomas. Invasive squamous cell carcinomas, yolk sac tumors, Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) and melanomas each represented approximately 10% of reported cases. For rhabdomyosarcoma, the alveolar and embryonal subtypes were reported with equal frequency, with both representing 70% of cases combined. The average patient age was 9.8 years. 48% and 35% were Intergroup Rhabdomyosarcoma Study clinical groupings I and III respectively. Managements were generally multimodal, and overall outcomes for the group were favorable. For invasive squamous cell carcinoma, the patients were all in their teenage years, with an average age at diagnosis of 15.2 years. A small subset of cases were associated with human papillomavirus and immunosuppression, and it is possible that immunosuppression has a role in vulvar squamous carcinogenesis in this population. One case was associated with lichen sclerosus. The patients with yolk sac tumors ranged in age from less than 1 year to 20 years (mean 12) and 67% of cases were stage I at presentation. An insufficient number of cases have been reported to define their prognosis, although some cases were notably aggressive. The few reported cases of melanoma are distinctive only because they were all associated with lichen sclerosus, suggestive of some role for the latter in their pathogenesis. The average age of patients reported with ES/PNET was 15 years (range 3.3 to 20). At least half of the reported cases were advanced stage at presentation, and patient outcomes were notably poor: 62.5% were dead of disease at follow-up. Pediatric vulvar malignancies are rare and are mostly comprised of 5 entities. Their accurate pathologic classification is necessary to facilitate optimal management.

Abstract
BACKGROUND/PURPOSE Melanoma is the most common skin cancer in children and often presents in an atypical fashion when compared to adults. The purpose of this review is to present an update on the epidemiology, surgical and medical management and prevention strategies in pediatric melanoma. METHODS A comprehensive review of the current literature on the epidemiology, surgical and medical management and prevention of adult and pediatric melanoma was performed by the authors and the results of this review are summarized in the manuscript. RESULTS Most recently, the incidence of melanoma in children has been declining, possibly owing to increased awareness and sun exposure prevention. The mainstay of therapy is surgical resection, often with sentinel lymph node biopsy. A positive sentinel node has prognostic value; however, completion node dissection is no longer recommended in the absence of clinically or radiographically positive nodes. Those with advanced disease also receive adjuvant systemic therapy using increasingly targeted immunologic therapies. CONCLUSIONS Sentinel lymph node positive patients no longer require completion lymph node dissection and instead may be followed by ultrasound. However, it is important to note that children have been excluded from most melanoma clinical trials to date, and therefore, recommendations for management are based on existing pediatric retrospective data and extrapolation from adult studies.

RESULTS A total of 4,561 pediatric melanomas of the skin were identified. There were 854 (18.7%) cases of melanoma of the head and neck (MHN) and 3,707 (81.3%) cases of melanoma of the body (MOB). The hazard ratio for MHN versus MOB was 1.6 (95% confidence interval: 1.3-2.1) after accounting for sex, race, and age. Of MHN sites, the hazard ratio for melanoma of the scalp and neck was 2.2 (1.1-4.7). The 2- and 5-year Kaplan-Meier overall survival for MHN were 94.6% and 90.7%, respectively, compared with 96.6% and 94.7%, respectively, for MOB (P < .01). CONCLUSIONS Survival outcomes of pediatric melanoma are notably related to anatomic site. Children with melanoma of the scalp and neck have the worst survival of all sites. Additionally, children who are older/white/male are at greater risk for worse survival outcomes. LEVEL OF EVIDENCE 3 Laryngoscope, 131:E635-E641, 2021.

Abstract
Importance Melanoma is one of the most common cancers worldwide, typically diagnosed in older adults. There is an increasing incidence in the younger population (age ≤40 years) in America. In addition, approximately 1 in 5 cases of melanoma affect the head and neck. However, there are limited data on the incidence of head and neck melanoma in the pediatric, adolescent, and young adult population in North America (United States and Canada). Objective To assess 20-year demographic and incidence changes associated with head and neck melanoma in the pediatric, adolescent, and young adult population in North America. Design, Setting, and Participants A descriptive analysis of retrospective data on head and neck melanoma from the North American Association of Central Cancer Registries' Cancer in North America public use data set from 1995 to 2014 was conducted. The data set currently includes 93% of the United States and 64% of the Canadian populations. Eligible data were from 12 462 pediatric, adolescent, and young adult patients (aged 0-39 years) with a confirmed diagnosis of melanoma (International Classification of Diseases-Oncology 3 histologic types 8720-8790) in primary head and neck sites: skin of lip, not otherwise specified (C44.0); eyelid (C44.1); external ear (C44.2); skin of other/unspecified parts of face (C44.3); and skin of scalp and neck (C44.4). The study was conducted from January 26 to July 21, 2019. Main Outcomes and Measures Log-linear regression was used to estimate annual percentage change in age-adjusted incidence rates (AAIRs) of head and neck melanoma. Results Of the 12 462 patients with head and neck melanoma included in the study, 6810 were male (54.6%). The AAIR was 0.51 per 100 000 persons (95% CI, 0.50-0.52 per 100 000 persons). In North America, the incidence of head and neck melanoma increased by 51.1% from 1995 to 2014. The rate was higher in the United States (AAIR, 0.52; 95% CI, 0.51-0.53 per 100 000 person-years) than Canada (AAIR, 0.43; 95% CI, 0.40-0.45 per 100 000 persons). In the United States, the incidence increased 4.68% yearly from 1995 to 2000 and 1.15% yearly from 2000 to 2014. In Canada, the incidence increased 2.18% yearly from 1995 to 2014. Male sex (AAIR, 0.55; 95% CI, 0.54-0.57 per 100 000 persons), older age (AAIR, 0.79; 95% CI, 0.79-0.80 per 100 000 persons), and non-Hispanic white race/ethnicity (AAIR, 0.79; 95% CI, 0.77-0.80 per 100 000 persons) were associated with an increased incidence of head and neck melanoma. Conclusions and Relevance The incidence of pediatric, adolescent, and young adult head and neck melanoma in North America appears to have increased by 51.1% in the past 2 decades, with males aged 15 to 39 years the main cohort associated with the increase.

Abstract
In Chinese medicine, herbal medicine is commonly used to treat individuals suffering from many types of diseases. We thus expected that some herbal medicines would contain promising compounds for cancer chemotherapy. Indeed, we found that Sanguisorba officinalis extracts strongly inhibit the growth of B16F10 melanoma cells, and we identified ellagic acid (EA) as the responsible ingredient. B16F10 cells treated with EA exhibited strong G1 arrest accompanied by accumulation of p53, followed by inactivation of AKT. Addition of a PTEN inhibitor, but not a p53 inhibitor, abrogated the EA-induced AKT inactivation and G1 arrest. The PTEN inhibitor also diminished EA-induced p53 accumulation. Furthermore, EA apparently increased the protein phosphatase activity of PTEN, as demonstrated by the reduced phosphorylation level of FAK, a protein substrate of PTEN. Furthermore, an in vitro PTEN phosphatase assay on PIP3 showed the direct modulation of PTEN activity by EA. These results suggest that EA functions as an allosteric modulator of PTEN, enhancing its protein phosphatase activity while inhibiting its lipid phosphatase activity. It is notable that a combination of EA and cisplatin, a widely used chemotherapy agent, dramatically enhanced cell death in B16F10 cells, suggesting a promising strategy in chemotherapy.

Abstract
Melanoma accounts for 7% of all cancers in adolescents ages 15-19 years but is an unexpected malignancy in younger children. The prevalence of malignant melanoma is very rare in children ages 1-4 years, but certain non-modifiable risk factors such as xeroderma pigmentosum, congenital melanocytic nevus syndrome and other inherited traits increase the risk for its development in these young children. Recent genomic studies have identified characteristics of pediatric melanoma that differ from conventional melanoma seen in adults. In this review the authors inform on the types of melanoma seen in children and adolescents, discuss similarities and differences in melanoma between children and adults, and discuss the role of imaging in the care of these children.

Abstract
Children and adolescents may be vulnerable to increased ultraviolet radiation exposure and greater risk for subsequent sun-related pathologies. This study examined the demographic, geographic, and phenotypic factors influencing sun exposure and protective behaviors among children and adolescents living in the United States. A cross-sectional survey on perceived sun exposure and protective behaviors was administered at three sports medicine clinics in California, Colorado, and Hawaii. Responses were measured with a 5-item frequency scale: Never, Rarely (25% of the time or less), Sometimes (50% of the time), Often (75% of the time or more), and Always. Sun protective behavior was examined using univariate and multivariate analyses. In total, 860 surveys were collected (52% female, 48% male; mean age 12.7 years). Females reported significantly greater frequency of using sunscreen (p = 0.001), staying in the shade or using an umbrella while in the sun (p = 0.004), and tanning (p < 0.001). Age was inversely associated with sunscreen use frequency (p < 0.001); the percentage of participants who reported always wearing sunscreen decreased as age increased. Participants in Hawaii reported using sunscreen less frequently than those in California and Colorado (p < 0.001). These results identify high-risk populations such as males, older adolescents, and Hawaii's youth who may not be practicing frequent sun protective behaviors. While it is important for youth to stay active, they must also be reminded to adopt protective behaviors while outdoors to prevent unnecessary sun damage and lower the risk of sun exposure complications.

Abstract
Paediatric melanoma is rare and challenging to diagnose. The three subtypes are Spitzoid melanoma, melanoma arising in a congenital melanocytic nevus, and conventional (also known as adult-type) melanoma. Spitzoid melanomas have characteristic histopathological and genomic aberrations. Despite frequent involvement of the sentinel lymph nodes, most cases have an uneventful clinical course. Among congenital nevi, the risk of melanoma varies by projected size in adulthood, with the greatest risk in large or giant nevi. The clinical course is generally aggressive and accounts for most melanoma-related deaths in childhood. In conventional melanoma, superficial spreading and nodular melanoma account for most cases, with risk factors and presentation largely similar to adult disease. In this Review, we discuss advances in histological diagnosis using adjunctive molecular assays, and summarise the genetic basis of paediatric melanoma.

Abstract
INTRODUCTION Malignant melanoma is increasing in frequency worldwide; however, this disease is rare in children. As large-scale studies on paediatric melanoma are lacking, management is currently often based upon the understanding of the disease process in adults. The aim of this study was to characterise cases of paediatric melanoma diagnosed in the Republic of Ireland over a 21-year period. METHODS This was a retrospective, multicentre study using national data provided by the National Cancer Registry of Ireland and individual practitioners. RESULTS Twenty-four cases of melanoma treated in 11 different centres were included in the study. The median patient age at diagnosis was 15 years. The majority of cases arose on the limbs. The median Breslow thickness in patients of the pre-pubertal age group was 8.25 mm, while in children more than 13 years, it was 1.65 mm. Eight patients had disease recurrence and five patients died. CONCLUSION The diagnosis of melanoma remains rare in children. This study contributes to our current understanding of malignant melanoma in paediatric patients; however, further investigation of the disease characteristics in this group is necessary to achieve optimal management of these cases and therefore improve outcomes.

Abstract
OBJECTIVES To characterize clinical differences among nonwhite/multiethnic vs white children, adolescents, and young adults with melanoma or atypical melanocytic neoplasms, including atypical Spitz tumors. PATIENTS AND METHODS A cohort of 55 patients (< 25 years of age) prospectively followed from 1995 to 2018 in the Stanford Pigmented Lesion and Melanoma Program was analyzed for differences in clinical presentation, including skin phototype, race/ethnicity, age, sex, tumor/melanoma characteristics, and outcome. RESULTS Seventeen patients (9 males and 8 females) were classified as nonwhite (predominantly skin phototype IV) and of Hispanic, Asian, or Black/African American ethnicity, and 38 patients (21 males and 17 females) were classified as white (predominantly phototypes I/II). Ages ranged from 6 months to 24 years, and median follow-up was 36 months (range 1-180 months). Melanomas were diagnosed in 87% of whites in our cohort, compared to 65% of nonwhites, with the remainder representing mainly atypical Spitz tumors. Lesions were usually brought to the attention of a health care provider by the patient or family (P < 0.05). Compared with whites, nonwhites were more likely to present at a younger mean age (10.9 years vs 15.4 years, P < 0.05) and with pink/clinically amelanotic tumors (59% vs 24%, P = 0.02). CONCLUSIONS This long-term prospective institutional study showed clinically relevant differences between nonwhite vs white children, adolescents, and young adults diagnosed with melanoma and atypical melanocytic neoplasms. Nonwhite patients presented at a younger age and had more clinically amelanotic melanocytic tumors. Increased recognition of clinical factors and risk of these tumors in nonwhites could result in earlier diagnosis.

Abstract
BACKGROUND Epidemiological knowledge and predictors of melanoma among children and adolescents in multiethnic populations are limited. PROCEDURE Using data from the Texas Cancer Registry (TCR) and the Surveillance, Epidemiology, and End Results (SEER) 13 database, we identified incident melanoma cases diagnosed at 0-20 years old during 1995-2013 in Texas and the United States, respectively. Using negative binomial regression, associations between demographic factors and melanoma incidence rates (IR) were evaluated by calculating incidence rate ratios (IRR) and 95% confidence intervals (CI). Annual percent change in IRs was assessed with joinpoint regression. RESULTS Overall, the melanoma IR was 4.16 (TCR, n = 634) and 4.84 (SEER, n = 1260) per million. Females, adolescents, non-Hispanic (NH) whites, and Hispanics had higher IRs compared with other groups (P < 0.05). In adjusted analyses, Hispanics had a higher incidence of melanoma than NH non-whites (Texas IRR = 2.17; 95% CI, 1.30-3.61; SEER IRR = 2.88; 95% CI, 1.97-4.21). In Texas, NH whites with melanoma were more likely to live in low poverty areas, whereas the opposite trend was observed in Hispanics. Melanoma IRs increased throughout 1995-2004 followed by an average annual decrease of 7.6% (95% CI, -12.6%, -2.2%) in Texas and 6.0% (95% CI, -8.5%, -3.4%) in SEER during 2005-2013 (P < 0.05). However, these decreasing trends were not observed among Hispanics or those <10 years old. CONCLUSION Although the overall melanoma IR in children and adolescents appears to be decreasing, this trend is not evident among Hispanics and young children, implicating the need for further research investigating the etiologies and risk factors in these groups.

Abstract
Objective To examine the diagnostic value of the sentinel lymph node biopsy in pediatric through young adult head and neck melanocytic tumors of unknown malignant potential. Study Design Retrospective case series. Setting Single academic institution. Subjects and Methods Demographics, histology, and outcomes were examined in 14 patients aged 4 to 24 years with head and neck melanocytic tumors of unknown malignant potential. Information on age at diagnosis, primary lesion characteristics, and sentinel lymph node biopsy were compared. Results Of 14 patients meeting criteria for head and neck melanocytic tumors of unknown malignant potential, 8 patients underwent sentinel lymph node biopsy (57%). Of those, 4 biopsies (50%) had positive sentinel nodes. All patients undergoing sentinel lymph node biopsy had primary lesions greater than 1 mm depth or mitotic rate of at least 1 mitosis per mm2. No patients had recurrence of their primary lesion at time of follow-up. Conclusion Our data show a high rate of node-positive sentinel lymph node biopsy for pediatric and young adult head and neck patients with melanocytic tumors of unknown malignant potential, supporting the value of sentinel lymph node biopsy in this population.

Abstract
BACKGROUND Germline variants in the melanocortin 1 receptor gene (MC1R) might increase the risk of childhood and adolescent melanoma, but a clear conclusion is challenging because of the low number of studies and cases. We assessed the association of MC1R variants with childhood and adolescent melanoma in a large study comparing the prevalence of MC1R variants in child or adolescent patients with melanoma to that in adult patients with melanoma and in healthy adult controls. METHODS In this retrospective pooled analysis, we used the M-SKIP Project, the Italian Melanoma Intergroup, and other European groups (with participants from Australia, Canada, France, Greece, Italy, the Netherlands, Serbia, Spain, Sweden, Turkey, and the USA) to assemble an international multicentre cohort. We gathered phenotypic and genetic data from children or adolescents diagnosed with sporadic single-primary cutaneous melanoma at age 20 years or younger, adult patients with sporadic single-primary cutaneous melanoma diagnosed at age 35 years or older, and healthy adult individuals as controls. We calculated odds ratios (ORs) for childhood and adolescent melanoma associated with MC1R variants by multivariable logistic regression. Subgroup analysis was done for children aged 18 or younger and 14 years or younger. FINDINGS We analysed data from 233 young patients, 932 adult patients, and 932 healthy adult controls. Children and adolescents had higher odds of carrying MC1R r variants than did adult patients (OR 1·54, 95% CI 1·02-2·33), including when analysis was restricted to patients aged 18 years or younger (1·80, 1·06-3·07). All investigated variants, except Arg160Trp, tended, to varying degrees, to have higher frequencies in young patients than in adult patients, with significantly higher frequencies found for Val60Leu (OR 1·60, 95% CI 1·05-2·44; p=0·04) and Asp294His (2·15, 1·05-4·40; p=0·04). Compared with those of healthy controls, young patients with melanoma had significantly higher frequencies of any MC1R variants. INTERPRETATION Our pooled analysis of MC1R genetic data of young patients with melanoma showed that MC1R r variants were more prevalent in childhood and adolescent melanoma than in adult melanoma, especially in patients aged 18 years or younger. Our findings support the role of MC1R in childhood and adolescent melanoma susceptibility, with a potential clinical relevance for developing early melanoma detection and preventive strategies.

Abstract
Although melanoma is a rare diagnosis in the pediatric population, advances in the management of adults with melanoma offer the prospect of promising therapeutic options for children. At this time, medical management is not considered curative but may reduce the risk of recurrence or prolong survival. Surgical management remains the mainstay of treatment. Medical therapy of pediatric melanoma is not thought to have a role for in situ, early-stage, or localized disease, but adjuvant therapy may have a role in improving the prognosis of patients with positive sentinel lymph node biopsy (SLNB), spread beyond the regional lymph node basin, metastatic disease, or recurrent disease. Medical treatment options include immunotherapies, particularly checkpoint inhibitors, and targeted therapies, which have provided improved toxicity profiles compared with traditional chemotherapy regimens in the setting of advanced disease. There is a growing body of pediatric-specific data relevant to the use of adjuvant therapies for advanced melanoma in children.

Abstract
BACKGROUND Melanoma is a rare diagnosis in the pediatric population. Differences in incidence, presentation, and survival distinguish pediatric melanoma from adult melanoma. In order to improve our understanding of pediatric melanoma, our case series investigates differences in incidence, age of onset, and anatomic site between male and female pediatric melanoma patients in Colorado between 1988 and 2015. METHODS All data were gathered from the Colorado Central Cancer Registry. A request for de-identified data on pediatric melanoma patients between 1988 and 2015 was made by the University of Colorado Department of Dermatology. Chi-square tests were used to compare the differences reported in melanoma between sex, age-groups, and site of lesion. RESULTS A total of 256 cases of melanoma were reported in Colorado in patients < 20 years of age between 1988 and 2015. Overall incidence of pediatric melanoma in Colorado increased from 1988 to 1999 but declined from 2001 to 2011. There was a significant predominance of female cases in the 10-14 age-group (P = 0.0477) and 15-19 age-group (P = 0.0472). Both groups had increased incidence of melanoma with increasing age. The mean age of onset for both sexes was 16 years old. Boys were more likely to have melanoma of the scalp and neck (P = 0.0523) and less likely to have melanoma of the leg (P = 0.0049). CONCLUSION Among the pediatric population, girls 10-14 and 15-19 years old are at a significantly increased risk of melanoma compared to boys in these age-groups. Our study found sex-specific differences in anatomic site consistent with prior literature. Further investigations should aim to identify causes for these sex-specific differences in order to better guide public health initiatives.

Abstract
BACKGROUND/OBJECTIVES Although pediatric and young adult skin cancer is uncommon, recent epidemiologic studies have shown pediatric melanoma to be on the rise in the United States. Using a population-based cancer registry, this study examined skin cancer burden and survival disparities in children and young adults. METHODS Linked data from the Florida Cancer Data System and U.S. Census were analyzed to elucidate skin cancer burden distribution and survival disparities in 1543 Florida children (0-9 years), adolescents (10-19 years), and young adults (20-24 years). These disparities were assessed according to sociodemographic groups such as sex, race, ethnicity, and neighborhood level socioeconomic status. A multivariable Cox regression model adjusted for sociodemographic, clinical, and tumor characteristics was used to predict survival. RESULTS Boys had a slightly greater burden of skin cancer among children (50.9%), whereas girls had the greatest burden for adolescents (54.5%) and young adults (60%). Survival differed between white, black, and other races; 1-year survival was 91.5% for whites and 77.9% for blacks. Average 3- and 5-year survival was comparable for blacks and whites. "Other" race had a 1- and 3-year survival of 96.2%. CONCLUSION Because skin cancer is on the rise, it is important to elucidate the burden and determinants associated with survival outcomes to identify high-risk pediatric and young adult populations. Understanding these factors in the Florida pediatric population may provide a base for future endeavors to create culturally competent cancer prevention programs through screening, health promotion, and literacy.

Abstract
BACKGROUND Vemurafenib, a selective inhibitor of BRAF kinase, is approved for the treatment of adult stage IIIc/IV BRAF V600 mutation-positive melanoma. We conducted a phase I, open-label, dose-escalation study in pediatric patients aged 12-17 years with this tumor type (NCT01519323). PROCEDURE Patients received vemurafenib orally until disease progression. Dose escalation was conducted using a 3 + 3 design. Patients were monitored for dose-limiting toxicities (DLTs) during the first 28 days of treatment to determine the maximum tolerated dose (MTD). Safety/tolerability, tumor response, and pharmacokinetics were evaluated. RESULTS Six patients were enrolled (720 mg twice daily [BID], n = 3; 960 mg BID [n = 3]). The study was terminated prematurely due to low enrollment. No DLTs were observed; thus, the MTD could not be determined. All patients experienced at least one adverse event (AE); the most common were diarrhea, headache, photosensitivity, rash, nausea, and fatigue. Three patients experienced serious AEs, one patient developed secondary cutaneous malignancies, and five patients died following disease progression. Mean steady-state plasma concentrations of vemurafenib following 720 mg and 960 mg BID dosing were similar or higher, respectively, than in adults. There were no objective responses. Median progression-free survival and overall survival were 4.4 months (95% confidence interval [CI] = 2.7-5.2) and 8.1 months (95% CI = 5.1-12.0), respectively. CONCLUSIONS A recommended and effective dose of vemurafenib for patients aged 12-17 years with metastatic or unresectable melanoma was not identified. Extremely low enrollment in this trial highlights the importance of considering the inclusion of adolescents with adult cancers in adult trials.

Abstract
The pediatric melanoma population is not well described, and current guidelines for their management are not well defined. Our study aims to identify this population, treatment modalities, and outcomes using a national population-based database. We reviewed the Surveillance, Epidemiology, and End Results database (2004–2008). Patients ≤21 years old with melanoma were included and grouped into ≤12 years of age, 13 to 18 years, and 19 to 21 years. Clinical characteristics were analyzed across the groups. A total of 1255 patients were included: 52.7 per cent were 19 to 21 years of age, 36.3 per cent were 13 to 18 years of age, and 11.0 per cent were ≤12 years of age. The 19- to 21-year-olds had the highest proportion of stage I (50.5%) versus ≤12 years of age (31.9%); the ≤12-year-olds had the highest proportion of stage IV (3.6%) versus 19 to 21 years of age (0.9%), P < 0.001. The 19- to 21-year-olds had the highest proportion receiving wide local excisions only (34.8%) versus ≤12 years of age (26.4%); the ≤12-year-olds had the highest proportion of patients without any surgeries (16.0%) versus 13 to 18 years of age (9.4%), P = 0.169. On adjusted analysis, the 19- to 21-year-olds had worse survival compared with ≤12 years of age (hazard ratio: 5.26, P = 0.017, 95% confidence interval 1.34–20.65). Disparities were found in the ≤12-year-old melanoma population, as they had later stage melanomas, less invasive surgery, and lower survival. Clearer prognostic factors are needed to better elucidate their management.

Abstract
Clinical trial enrollments in adolescents and young adults (AYA) with cancer have historically been lower than those in pediatric and older adult populations. We sought to examine therapeutic trial enrollment rates at our cancer center. We performed a retrospective evaluation of AYA patients treated before and after the first checkpoint inhibitor trial opened at our cancer center in 2007. We examined gender, stage at presentation and insurance status in terms of trial enrollment. We compared the trial participation rate of AYA patients with that of older adults. In this adult facility, 12.7% (1,831) of total patients were between age 15 and 39. Overall therapeutic clinical trial rate was 17.6% which increased to 19.8% since 2007. Both nodal disease or metastatic disease at presentation was associated with increasing odds of trial enrollment (OR = 5.36 and P < 0.001 for nodal disease and OR = 7.96 and P < 0.001 for metastatic disease). There was a nonstatistically significant trend toward improved 3-year overall survival in the AYA patients with advanced presentation that enrolled on clinical trials compared with those not enrolled on trials since 2007. AYA clinical trial enrollment at a comprehensive care center melanoma program was higher than reported in the literature overall for AYA patients. This 1,831 patient cohort may provide a foundation for more detailed investigation toward quantifying the effects of clinical trial enrollment in terms of age-specific benefits and toxicities for AYA patients with malignancies that have their peak incidence in older adults.
