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
BACKGROUND Melanomas in the first 2 decades of life are uncommon and poorly understood. OBJECTIVE To assess clinicopathologic features and survival of children (≤11 years) and adolescents (12-19 years) diagnosed with melanoma. METHODS A pooled cohort of 514 patients was analyzed (397 Dutch, 117 Australian; 62 children, 452 adolescents). Pathology reports were reevaluated to determine melanoma subtypes. Multivariable Cox models were generated for recurrence-free survival (RFS) and overall survival (OS). RESULTS Melanoma subtypes were conventional melanoma (superficial spreading, nodular, desmoplastic, and acral lentiginous), spitzoid melanoma, and melanoma associated with a congenital nevus in 428, 78, and 8 patients, respectively. Ten-year RFS was 91.5% (95% confidence interval [CI], 82.4%-100%) in children and 86.4% (95% CI, 82.7%-90.3%) in adolescents (P = .32). Ten-year OS was 100% in children and 92.7% (95% CI, 89.8%-95.8%) in adolescents (P = .09). On multivariable analysis possible only for the adolescent cohort due to the small number of children, ulceration status, and anatomic site were associated with RFS and OS, whereas age, sex, mitotic index, sentinel node status and melanoma subtype were not. Breslow thickness >4 mm was associated with worse RFS. LIMITATIONS Retrospective study. CONCLUSIONS Survival rates for children and adolescents with melanomas were high. Ulceration, head or neck location and Breslow thickness >4 mm predicted worse survival in adolescents.

Abstract
BACKGROUND People of African, Asian, Hispanic or Latino, Pacific Islander, and Native Indian descent are considered people of color by the Skin of Color Society (SOCS). OBJECTIVES In this study, we assess incidence, risk factors, clinical characteristics, histopathology, treatment, and survival for skin malignancies in people of color as defined by the SOCS, by systematically reviewing the literature. METHODS An electronic literature search of the PubMed, EMBASE, and MEDLINE databases was performed. Articles published from 1 January 1990 through 12 December 2020 were included in the search. RESULTS We identified 2666 publications potentially meeting the study criteria. Titles and abstracts of these studies were reviewed and 2353 were excluded. The full text of 313 articles were evaluated and 251 were included in this review. CONCLUSION Differences in incidence, patterns, treatment, and survival exist among people of color for cutaneous malignancies. Further research and initiatives are needed to account for and mitigate these differences.

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
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
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
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
The clinicopathologic features of pediatric melanoma are distinct from those of the adult counterpart. For example, most childhood melanomas exhibit a uniquely favorable biologic behavior, save for those arising in large/giant congenital nevi. Recent studies suggest that the characteristically favorable biologic behavior of childhood melanoma may be related to extreme telomere shortening and dysfunction in the cancer cells. Herein, we review the genomic profiles that have been defined for the different subtypes of pediatric melanoma and particularly emphasize the potential prognostic value of telomerase reverse transcriptase alterations for these tumors.

Abstract
Paediatric melanoma, although rare, is the most common skin cancer in children. Our current knowledge on paediatric melanoma incidence trends is expanding, as several studies have addressed this issue with conflicting results. Known risk factors for paediatric melanoma include family history of melanoma, a previous history of malignancy, large congenital nevi, numerous melanocytic nevi, sunburns, increased UV exposure and a sun-sensitive phenotype. In younger children, melanoma more often presents with atypical features, such as a changing, amelanotic or uniformly coloured, often bleeding lesion, not fulfilling in most cases the conventional ABCDE criteria. The major differential diagnoses are melanocytic nevi, proliferative nodules in congenital nevi and atypical Spitz tumours. Moreover, in the younger age group non-Caucasian children are over-represented, tumours tend to be thicker and lymph nodes are often involved. Despite the frequent diagnosis at an advanced stage, the overall survival is fair in paediatric melanoma. Specific guidelines for management of melanoma in children do not exist, and most often the disease is treated similarly to melanoma in adults.

Abstract
BACKGROUND Skin cancer screening interventions often relay on the involvement of general practitioners (GPs). Many interventions up to now have been directed to training approaches focusing on the clinical features of skin malignancies to increase GPs skill in skin cancer recognition. METHODS Based on the available current knowledge about skin cancer epidemiology and risk factors, we built up a 5-point checklist to help GPs in triaging patients to be referred to a dermatologist. RESULTS Five-point check-list: 1) visible sun damaged skin on exposed areas (red and brown to black macules and crusts on visible skin); 2) more than 20 nevi on the arms; 3) one or more ABCD positive lesions (flat, large and asymmetric macules); 4) one or more EFG positive lesions (elevated, firm and growing skin lesions); 5) a pigmented lesion larger than 1.5 cm in diameter. CONCLUSIONS Our aim was to provide a short list of practical rules, easy to adopt into a routine practice, in order to achieve a more effective triage of patients requiring a dermatology consultation for skin cancer examination. The novelty of the proposed method relies on the approach. The proposed method does not require the GP to diagnose skin cancer. The aim is to involve GPs in the selection of patients to be referred to the specialist, in order to reduce the waiting time while avoiding the risk to leave cancers untreated.

Abstract
Melanoma is uncommon in the pediatric age range, but is increasing in frequency and often presents with atypical features compared to the classic ABCDE criteria common to adult melanoma cases. Moreover, many melanocytic neoplasms in childhood pose diagnostic challenges to the pathologist, and sometimes cannot be unequivocally classified as benign nevi or melanoma. This chapter addresses the evaluation and management of pediatric patients with melanoma and atypical melanocytic neoplasms, including the roles of and unresolved questions surrounding sentinel lymph node biopsy, completion lymphadenectomy, adjuvant therapy, and treatment of advanced disease.

Atypical Spitz tumors in patients younger than 18 years. J Am Acad Dermatol 2014; 72:37-46.

Abstract
BACKGROUND Diagnosis and proper management of atypical Spitz tumors in pediatric age are still controversial. OBJECTIVE We sought to investigate the clinicopathological and molecular features of atypical Spitz tumors in patients aged 18 years or younger. METHODS We performed a retrospective clinicopathological and fluorescence in situ hybridization study on 50 pediatric atypical Spitz tumors. RESULTS Parameters that were significantly correlated with a diagnosis of atypical Spitz tumors over Spitz nevus included asymmetry, level IV/V, lack of maturation, solid growth, nuclear pleomorphism, high nuclear-cytoplasmic ratio, atypical and deep mitoses, and more than 6 mitoses/mm(2). In the atypical Spitz tumors group, a significantly higher mitotic rate was observed in prepuberal age (P = .04). The 4-probe fluorescence in situ hybridization melanoma assay did not discriminate atypical Spitz tumors from Spitz nevi. Heterozygous 9p21 loss was found in 3 of 37 cases and homozygous 9p21 loss in 2 of 37 cases. Only 1 child experienced a fatal outcome, showing genetic abnormalities by melanoma fluorescence in situ hybridization probe and a heterozygous 9p21 deletion. LIMITATIONS The limited number of adverse outcomes did not allow the prognostic analysis of single morphologic features. CONCLUSION Pediatric atypical Spitz tumors are associated with minimal lethal potential. Atypical Spitz tumors require complete excision and careful follow-up while our data do not support any clinical benefit for the sentinel lymph node biopsy procedure and completion lymphadenectomy.

Abstract
BACKGROUND This study compares the natural history and treatment outcomes of cutaneous melanoma in teenagers and young adults to determine if exclusion of teenagers from investigative trials is justified. PATIENTS AND METHODS This is a chart review of patients between the ages of 13 and 40 years treated at The University of Texas MD Anderson Cancer Center for melanoma. Data related to the natural history and treatment outcomes were collected. Statistical tools were used to compare characteristics between teenagers and young adults. Cox proportional hazard models were utilized to examine the association between age group and overall survival. RESULTS Of the 476 patients, 109 were teenagers and 367 were young adults. Both groups had comparable disease stage, pathology, and rates of metastasis. Initial disease stage and pathology significantly influenced survival. Sixty-six of 452 patients with skin melanoma developed metastasis. Teenagers survived better than young adults from diagnosis of the skin primary and after development of systemic metastasis. Teenagers tolerated and benefited from interleukin-2-based systemic therapy and targeted therapies as well as the young adults. CONCLUSIONS Because of the similarities in natural history and treatment outcomes between teenage and young adult patients, it is recommended that teenage patients be officially enrolled on adult melanoma therapeutic trials.

Abstract
BACKGROUND The management of pediatric melanoma (PM) has largely been extrapolated from adult data. However, the behavior of PM appears to differ from its adult counterparts. Therefore, an international PM registry was created and analyzed. METHODS Twelve institutions contributed deidentified clinicopathologic and outcome data for patients diagnosed with PM from 1953 through 2008. RESULTS Overall survival (OS) data were reported for 365 patients with invasive PM who had adequate follow-up data. The mean age of the patients was 16 years (range 1 year-21 years). The 10-year OS rate, 80.6%, tended to vary by patient age: 100% for those aged birth to 10 years, 69.7% for those aged > 10 years to 15 years, and 79.5% for those aged > 15 years to 20 years (P = .147). Patients with melanomas measuring ≤ 1 mm had a favorable prognosis (10-year OS rate of 97%), whereas survival was lower but similar for patients with melanomas measuring > 1 mm to 2 mm, > 2 mm to 4 mm, and > 4 mm (70%, 78%, and 80%, respectively; P = .0077). Ulceration and lymph node metastasis were found to be correlated with worse survival (P = .022 and P = .017, respectively). The 10-year OS rate was 94.1% for patients with American Joint Committee on Cancer stage I disease, 79.6% for those with stage II disease, and 77.1% for patients with stage III disease (P < .001). CONCLUSIONS Tumor thickness, ulceration, lymph node status, and stage were found to be significant predictors of survival in patients with PM, similar to adult melanoma. There is a trend toward increased survival in children aged ≤ 10 years versus adolescents aged > 10 years. Further analyses are needed to probe for potential biological and behavioral differences in pediatric versus adult melanoma.

Abstract
BACKGROUND Melanoma incidence and mortality rates have increased over the past 30 years in the Caucasian population. In Brazil, data on non-capital cities are scarce, making epidemiological stu dies necessary. OBJECTIVES To evaluate the incidence of and classify cutaneous melanomas in Blumenau from 1980 to 2009. METHOD Data from 1002 histopathological examinations of individuals from Blumenau were collected, considering sex, age, primary site of involvement, histological type, level of invasion (Clark's level) and tumor thickness (Breslow's depth). The gross and adjusted coefficients of annual incidences were calculated based on the number of melanoma cases and the population estimated by the Brazilian Institute of Geography and Statistics (IBGE) between 1980 and 2009. RESULTS The incidence rates of melanoma reached 22.4 cases per 100,000 inhabitants/year; 31.5 in women and 30.4 in men at the adjusted rate. The incidence rates standardized by decade, age and sex were 141 male and 103 female cases per 100,000/inhabitants aged 65 to 69 years. Superficial spreading melanoma occurred in 53% of the cases, followed by nodular melanoma (37%), and the primary site of involvement was the trunk (47%). 62.5% of the cases were diagnosed early, with Breslow < 1 mm. CONCLUSION The incidence of malignant melanoma has increased fivefold from 1980 to 2009 and early diagnosis has increased 151% as a result of primary prevention.

Abstract
OBJECTIVE The aim of this study was to determine the influence of age on outcome in pediatric melanoma patients and to identify factors associated with positive lymph node status in this population. METHODS A retrospective review of a prospective pediatric melanoma database, using sentinel lymph node biopsy (SLNB), from 1992 to 2006, identified 109 patients with the primary diagnosis of melanoma. Patient age was dichotomized as prepubescent (<10 years of age) and adolescent (≥10-18 years of age). Factors investigated included patient race, sex, and lymph node status and tumor thickness, Spitzoid or Non-Spitzoid histology, radial growth phase, and vascular invasion. The Fisher's exact test was used to compare patient groups. Time-to-event analysis was performed using the Kaplan-Meier method. RESULTS There were 25 prepubescent and 84 adolescent patients. Prepubescent patients were more often non-White, had greater tumor thickness, more spitzoid tumors and more vascular invasion. Ten-year overall survival (OS) was 89% and 10-year event-free survival (EFS) was 73%. Among 57 patients who had an SLNB, prepubertal patients had a higher percentage of sentinel lymph node positivity. The odds having a positive SLNB decreased by 13% each year with increasing age. Patients with a tumor thickness ≥2.01 mm had higher odds of having a positive lymph node compared with those patients with a tumor thickness ≤1.0. CONCLUSIONS This is the largest known study of prepubertal melanoma patients. Although OS and EFS did not differ by age groups, younger ages showed increased risk of lymph node metastasis and thicker tumors. This suggests that the younger pediatric patients may have a disease that differs biologically from that of the older pediatric patients.

Abstract
CONTEXT Cutaneous melanoma in childhood (CMC) is rare; therefore, its prognostic factors and biologic behavior, and the effectiveness of adjuvant techniques for CMC remain mostly unknown. OBJECTIVE To review the most useful, evidence-based practice criteria for establishing the diagnosis of CMC, for which universally accepted criteria are lacking, in order to facilitate the interpretation and comparison of the results from different institutions, and to perform systematic reviews and meta-analysis. DATA SOURCES A comprehensive review of the most relevant previous single-institution series reported in the literature since 1990, including our cumulative experience of 137 cases of primary cutaneous and mucosal melanoma in patients younger than 18 years. Special characteristics of melanoma in children are discussed, regarding clinical settings and risk factors, helpful histologic features, and immunohistochemical patterns for diagnosis and prognosis. CONCLUSIONS Careful analysis of histologic features as well as the additional information provided by immunohistochemistry should allow for a correct diagnosis in most cases of melanoma in children. Although it seems that pediatric patients with melanoma have higher survival probability than adults, still a number of children will develop metastasis and die of their disease, particularly when melanoma is diagnosed after puberty. Until further studies more accurately determine the prognosis, a prudent approach to CMC diagnosis and therapy seems to follow the same principles as those established for adult melanoma.

Abstract
BACKGROUND Cutaneous melanoma in childhood is rare; therefore, its prognostic factors and biologic behavior and the effectiveness of adjuvant diagnostic techniques in this group remain mostly unknown. METHODS The authors conducted a retrospective, observational study on the prognostic significance of clinical and pathologic findings from 137 cutaneous and mucosal melanomas in patients aged <18 years that were reviewed by the pathology department of a large cancer center during the period from 1992 to 2006. RESULTS Univariate analysis indicated that there was a significantly greater risk of metastases for patients who had previous nonmelanocytic malignancies, nodular histologic type, fusiform or spitzoid cytology, high Breslow thickness, vertical growth phase, high dermal mitotic activity, ulceration, and vascular invasion. Adjacent nevus and radial growth phase were associated with a better prognosis. Twelve patients (10.3%) died during follow-up. Decreased overall survival was related significantly to age >10 years, previous nonmelanocytic malignancy, high Breslow thickness, high Clark level, and the presence of metastases at diagnosis. All patients who died were aged ≥ 11 years, and 8 of those patients had metastases at diagnosis. In multivariate analysis, higher Breslow thickness predicted an increased risk of metastases, whereas age >10 years and the presence of metastases at diagnosis were associated with decreased survival. CONCLUSIONS Similar to adults, the detection of metastases at diagnosis in children with melanoma was 1 of the main factors that influenced overall survival. Melanomas that were detected in children aged <11 years appeared to have a less aggressive behavior than those detected in adults.

Abstract
Pediatric melanoma is difficult to study because of its rarity, possible biological differences in preadolescents compared with adolescents, and challenges of differentiating true melanoma from atypical spitzoid neoplasms. Indeterminant lesions are sometimes designated as melanocytic tumors of uncertain malignant potential (MelTUMPs). We performed a retrospective, single-institution review of melanomas, MelTUMPs and Spitz nevi with atypical features (SNAFs) in patients at 21 years of age and younger from 1995 to 2008. We identified 13 patients with melanoma, seven with MelTUMPs, and five with SNAFs. The median age for melanoma patients was 17 years, 10 for MelTUMPs, and six for SNAFs. Of the 13 melanoma patients, only four were younger than 15 years, while six were adolescents, and three were young adults. Nine melanoma patients (69%) were female. The most common histologic subtype was superficial spreading. The median depth for melanomas was 1.2 mm, and 3.4 mm for MelTUMPs. Microscopic regional nodal involvement detected on elective or sentinel lymph node (SLN) dissection was present in 2/10 (20%) of primary melanomas and 2/6 (33%) of Mel-TUMPs. Complete lymphadenectomy was performed on four melanoma patients, with three positive cases. Patient outcome through March 31, 2009 revealed no in-transit or visceral metastasis in patients with MelTUMPs or SNAFs. One SLN-positive patient (8%) with melanoma developed recurrent lymph node and liver metastasis and died 15 months after primary diagnosis. Our data highlight the rarity, female predominance, and significant rate of SLN positivity of pediatric melanoma. The high rate of MelTUMPs with regional nodal disease reinforces the need for close follow-up.

Abstract
Background Malignant mela-noma is a rare neoplasm in the pediatric population, but its incidence has risen in recent years. Methods The literature was reviewed to define the current clinical and pathologic features of pediatric melanoma, highlighting the similarities and differences between adult and pediatric melanoma. Results Distinctive features of this disease, including frequency and type of genetic abnormalities, predisposing conditions, clinical presentation, stage at diagnosis, prognostic features, and frequency of sentinel lymph node positivity are emphasized. Treatment strategies, extrapolated from adult mela-noma trials, are also discussed. Conclusions Despite the differences between pediatric and adult melanoma, survival rates are similar and are improving in both populations. Further studies will help delineate the pathogenesis of both adult and pediatric melanoma, with the goal of contributing to early detection and improved survival.
