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 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/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.

Abstract
PURPOSE OF REVIEW To inform pediatric providers of the clinical characteristics, underlying genetic drivers, and therapeutic options for skin cancer arising in childhood and adolescence. RECENT FINDINGS The incidence of melanoma in pediatric patients has been declining in the past decades. Pediatric-specific diagnostic criteria should be utilized when assessing lesions concerning for melanoma to better account for the different presentations seen in pediatric disease compared with adults, such as an increased prevalence of amelanotic melanoma or frequent mimic of benign pediatric lesions. Pediatric melanoma often presents with a higher histopathologic stage and a higher Breslow depth as compared with adult melanoma. Pediatric nonmelanoma skin cancer including basal cell carcinoma and squamous cell carcinoma are associated with genetic conditions and immunosuppression, both iatrogenic and inherited. SUMMARY Melanoma in pediatric patients often presents differently from conventional adult melanoma, including Spitz melanoma and melanoma associated with congenital melanocytic nevi. Pediatric patients with nonmelanoma skin cancers should be evaluated for predisposing risk factors. More research on therapeutic options for pediatric skin cancer is vital to understanding the tolerance and response of our pediatric patients to therapies that are more frequently utilized in adult disease.

Abstract
Aim: Malignant melanoma is the most frequent skin cancer in children and adolescents. It comprises 1–3% of all malignancies. In this study, we aimed to evaluate the clinical aspects, histopathologic features, and treatment outcomes of our patients with malignant melanoma. Material and Methods: Patients aged <15 years who were treated between 2003 and 2018 for malignant melanoma were retrospectively analyzed. Results: Seventeen patients (10 females, 7 males), with a median age of 7 years (range, 7 months-13 years) were evaluated. Five patients had congenital melanocytic nevi. All had cutaneous melanoma except one with mucosal (conjunctival) melanoma. The most frequent primary tumor site was the lower extremities (35%). Sentinel lymphoscintigraphy, sentinel node biopsy, and PET/CT were performed as the staging procedures at initial diagnosis. Localized disease was present in eight patients; nine had regional lymph node metastasis. The only treatment was surgery in localized disease; surgery and adjuvant interferon treatment was given in patients with regional lymph node metastasis. Three developed distant metastasis (bone, lung, brain) at a median of 9 months. A three-year-old patient received a BRAF inhibitor (vemurafenib), and a 13-year-old patient received a check point inhibitor (ipilimumab); both died of progressive disease. The median follow-up for all patients was 25 months. The 5-year overall survival was 76.6%. Conclusion: Although malignant melanoma is rare in children, prognosis is good if diagnosed early. Physicians should be aware of skin lesions and full-layer biopsy should be obtained in suspicious skin lesions. Patients with congenital melanocytic nevi should also be followed up cautiously.

Abstract
Despite advances in the treatment of many pediatric solid tumors, children with aggressive and high-risk disease continue to have a dismal prognosis. For those presenting with metastatic or recurrent disease, multiple rounds of intensified chemotherapy and radiation are the typical course of action, but more often than not, this fails to control the progression of the disease. Thus, new therapeutics are desperately needed to improve the outcomes for these children. Recent advances in our understanding of both the immune system's biology and its interaction with tumors have led to the development of novel immunotherapeutics as alternative treatment options for these aggressive malignancies. Immunotherapeutic approaches have shown promising results for pediatric solid tumors in early clinical trials, but challenges remain concerning safety and anti-tumor efficacy. In this review, we aim to discuss and summarize the main classes of immunotherapeutics used to treat pediatric solid tumors.

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
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 The diagnosis and management of pediatric melanomas is challenging given the presence of both melanomas and histologically aggressive Spitz tumors of undetermined biological significance (S-UBS) in this age group. Study objectives were to examine: factors leading to diagnostic delays, therapy side effects and patient outcomes in these diagnostic groups. METHODS A retrospective case review was performed using The University of Michigan's pediatric oncology database over a 13-year timespan. Patients referred to our clinic for consideration of interferon therapy due to a diagnosis of a stage III melanoma or aggressive appearing S-UBS with significant lymph node involvement were included. RESULTS We found two major causes of diagnosis delay: patients with amelanotic lesions misdiagnosed as having a wart and cases reviewed by non-expert pathologists upfront. The side effects from interferon therapy requiring dose adjustments included neutropenia, thrombocytopenia and mood disturbances. There was wide variability in surveillance scan utilization, therefore leading to variability in patient radiation exposure. Unlike melanoma patients, none of the S-UBS patients experienced disease progression or death. CONCLUSIONS This study highlights the challenges with the initial clinical diagnosis and pathological sub-categorization of the pediatric S-UBS/melanoma spectrum of skin lesions and emphasizes the role of expert pathology review upfront. Further, education at the primary care level could improve accurate and timely diagnoses. Earlier diagnosis could spare patients from more extensive interventions, metastatic spread or adverse outcomes in this patient population. This study is limited due to its retrospective, single-institution perspective.

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
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
Malignant melanoma can affect patients of any age. It has been well documented that the overall incidence of melanoma has increased in the past several decades, and this increase extends to the pediatric population (both preadolescent and, to a greater extent, adolescent children). Melanoma in adolescents, commonly defined as patients 11 to 19 years of age, behaves similarly to melanoma in adults; however, there are a number of distinct differences in the presentation and prognosis of melanoma in the preadolescent population. Though our treatment options for melanoma are increasing with the advent of novel drugs and clinical trials, the rarity of pediatric melanomas often excludes this population from clinical studies. The treatment options for the pediatric patient are predominantly based on adult clinical trials. Awareness of the differences in clinical presentation, as well as management of melanoma in younger patients compared with their adult counterparts, is crucial to guarantee prompt and appropriate care.

Abstract
BACKGROUND Pegylated interferon α-2b (IFN α-2b) improves disease-free survival in adults with resected stage III melanoma. We conducted a study to determine the feasibility and safety of incorporating pegylated IFN α-2b as adjuvant therapy in the treatment of children and adolescents with high-risk melanoma. Pharmacokinetic studies of IFN α-2b and neuropsychological and quality of life (OL) assessments were performed. PATIENT AND METHODS Eligible patients with resected American Joint Committee on Cancer Stage IIC, IIIA, and IIIB cutaneous melanoma received nonpegylated IFN α-2b 20 million units/m(2) /day intravenously 5 days per week for 4 weeks (induction) followed by pegylated IFN α-2b 1 μg/kg/dose weekly subcutaneously (SQ) for 48 weeks (maintenance). RESULTS Twenty-three patients (15 females, median age 10 years) were enrolled. All patients completed induction therapy; five patients did not complete maintenance therapy either because of recurrent disease (n = 2) or toxicity (n = 3). The most common grade 3 and 4 toxicities of pegylated IFN α-2b were neutropenia (35%) and elevated liver transaminases (17%). The median nonpegylated IFN α-2b AUC0-∞ (5,026 pcg⋅hr/ml) was similar to adults. The median pegylated IFN α-2b exposure (48,480 pcg⋅hr/ml) was greater than the cumulative weekly exposure for nonpegylated IFN α-2b administered SQ three times per week (TIW). Validated measures demonstrated an improvement in QOL scores and no decline in psychological functioning over the course of therapy. CONCLUSIONS Pegylated IFN α-2b 1 μg/kg/dose SQ weekly as maintenance therapy in children and adolescents with high-risk melanoma is feasible with tolerable toxicity and appears to yield higher exposures than nonpegylated IFN α-2b administered SQ TIW.

Abstract
BACKGROUND Studies suggest that the biology of pediatric and adolescent melanoma differs from that of adult disease. We report the largest series to date examining the natural history of pediatric and adolescent melanoma. We aim to elucidate the natural history of pediatric and adolescent melanoma and to examine the appropriateness of diagnostic and therapeutic modalities developed for adults and that are currently being used in children. METHODS A retrospective cohort study was conducted of patients with an index diagnosis of cutaneous non-metastatic melanoma from 1998 to 2011 using the National Cancer Data Base (NCDB; n = 420,416). Three age-based cohorts were analyzed: 1-10 years (pediatric), 11-20 years (adolescent), and ≥21 years (adult). Multivariate analyses were used to identify factors associated with overall survival (OS). RESULTS Pediatric melanoma patients have longer OS than their adolescent (hazard ratio [HR] 0.50, 95 % CI 0.25-0.98) and adult counterparts (HR 0.11, 95 % CI 0.06-0.21). Adolescents have longer OS than adults. No difference was found in OS in pediatric patients who are node-positive versus node-negative. In pediatric patients, sentinel lymph node biopsy and completion lymph node dissection are not associated with increased OS. In adolescents, nodal positivity is a significant negative prognostic indicator (HR 4.82, 95 % CI 3.38-6.87). CONCLUSIONS Age-based differences in melanoma outcomes warrant different considerations for diagnostic and therapeutic approaches in each group in order to maximize quality of life while minimizing complications and costs. Prospective, multicenter studies should evaluate the role of diagnostic procedures for pediatric patients.

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.

Abstract
The past decade has seen several anticancer immunotherapeutic strategies transition from "promising preclinical models" to treatments with proven clinical activity or benefit. In 2013, the journal Science selected the field of Cancer Immunotherapy as the overall number-1 breakthrough for the year in all of scientific research. In the setting of cancer immunotherapy for adult malignancies, many of these immunotherapy strategies have relied on the cancer patient's endogenous antitumor T-cell response. Although much promising research in pediatric oncology is similarly focused on T-cell reactivity, several pediatric malignancies themselves, or the chemo-radiotherapy used to achieve initial responses, can be associated with profound immune suppression, particularly of the T-cell system. A separate component of the immune system, also able to mediate antitumor effects and less suppressed by conventional cancer treatment, is the NK-cell system. In recent years, several distinct immunotherapeutic approaches that rely on the activity of NK cells have moved from preclinical development into clinical testing, and some have shown clear antitumor benefit. This review provides an overview of NK cell-based immunotherapy efforts that are directed toward childhood malignancies, with an emphasis on protocols that are already in clinical testing.

Abstract
PURPOSE OF REVIEW To inform pediatricians of the challenges of detection of melanoma in children and adolescents as well as to instruct on proper biopsy technique of suspicious lesions. RECENT FINDINGS The incidence of melanoma in children and adolescents is on the rise with an average increase of 2% per year. Rates of change are higher in adolescent girls and locations with low UV-B exposure. Standard Amelanotic, Bleeding, Bump, Color uniformity, De novo, any Diameter (ABCD) detection criteria fail to detect most childhood melanomas. Tumor thickness and sentinel lymph node status are the most important prognostic factors. Artificial tanning use is prevalent among adolescent girls and likely contributes to the growing incidence of melanoma in this group. SUMMARY Childhood melanoma is often amelanotic and may also appear as raised or ulcerated lesions commonly mistaken for warts or other benign skin conditions. Excision and full-thickness punch biopsies are indicated for suspicious lesions, whereas shaves and small punch biopsies are to be avoided. Pediatric patients more frequently have positive sentinel lymph nodes and increased tumor thickness, yet similar survival compared with adults.

Abstract
OBJECTIVE To describe a series of cutaneous melanoma in children collected by the Italian Rare Tumors in Pediatric Age project. STUDY DESIGN From 2000 to 2012, 54 patients younger than 18 years of age were prospectively registered and treated at 12 Italian pediatric centers on the basis of the same diagnostic/therapeutic recommendations and with the same forms to record clinical data. RESULTS Considering the estimated annual incidence in Italy, the registered cases accounted for 30% of those expected in children and 10% of adolescents. Clinically, 47% of the tumors were amelanotic and 81% were raised, 39% of cases had tumor thickness >2 mm, and 36% had lymph node involvement. For the whole series, 5-year event-free survival and overall survival rates were 75.2% and 84.6%, respectively. Patient survival correlated with tumor stage and ulceration. No relapses were recorded for T1-2 (thickness <2 mm), N0, and stage 0-I-II cases. CONCLUSION We suggest that the variables influencing survival in children with melanoma are the same as for adults, the clinical approach used in adults is feasible in children, and pediatric cases are more likely to have advanced disease at diagnosis but similar survival. New effective drugs are needed for advanced disease, and biological studies and international cooperative schemes are warranted.

Abstract
The rising incidence of melanoma in children has brought increased attention to the clinical and pathologic diagnosis of pigmented lesions in the pediatric age group. Although melanoma in infancy and early childhood is often associated with large congenital nevi, in older children and teenagers it is most often sporadic, occurring in patients with a low skin phototype and substantial sun exposure. The rarity of this potentially fatal disorder demands astute clinical attention and a high index of suspicion for atypical lesions in pediatric patients. The challenges include the difficult decision of whether to biopsy and an often equivocal pathologic diagnosis. These diagnostically challenging and equivocal lesions lead to a degree of uncertainty regarding additional workup, prognosis, potential therapy, and follow-up plans. Consultation with a specialty dermatopathologist can be very helpful, and advanced molecular diagnostic techniques may be used in selected circumstances. Although still controversial, good evidence exists to justify a role for sentinel lymph node biopsy. Patients with atypical melanocytic proliferations have a high rate of positive sentinel lymph nodes; however, their outcomes are clearly better than in similarly staged adults with conventional melanoma. With the multiple variables involved and the relative lack of prospectively derived evidence, clinical decision-making is challenging and patients and families may experience considerable stress. This article provides data and weighs the pros and cons of a rationale for decision-making in pediatric and young adult patients with diagnostically challenging melanocytic lesions.

Abstract
Skin melanoma is an extremely rare disease at pediatric age and its incidence increases with age. Links with predisposition syndrome exists (giant congenital naevus, xeroderma pigmentosum). Diagnosis is often difficult and distinction between benign or malignant lesion is sometime impossible (Spitzoid naevus, melanocytic neoplasms) leading to the diagnosis of "melanocytic tumor of uncertain malignant potential" (MELTUMP). Atypical features (amelanotic or raised lesions, atypical histotype) are frequent leading to delay in treatment. Diagnosis and treatment require expertise for pathologists and dermatologists pediatricians. Invasive melanomas are of poor prognosis despite recent progress in adult treatment. Early and rigorous treatment of suspect skin lesions is necessary.

Abstract
Mucosal malignant melanoma is a rare but aggressive neoplasm with high rates of recurrence and death. It is known that two-thirds of mucosal melanoma cases arise in the nasal cavity and paranasal sinuses in adults. However, there have been few studies until now on children with mucosal malignant melanoma and the related treatment. We report on a 10-year-old girl with mucosal malignant melanoma presented as a nasal polyp, which was removed via endoscopic sinus surgery and adjuvant chemotherapy without recurrence.

Abstract
PURPOSE The purpose of this study was to describe the use of lymphoscintigraphy and sentinel lymph-node biopsy (SLNB) for the management of children with melanoma and sarcomas. We report the experience of two children's hospitals that utilize this technique to identify sentinel lymph nodes for lymph-node biopsy and dissection. METHODS We identified 56 patients (median age 10.8 years) who underwent 58 lymphoscintigraphy procedures. There were 33 patients with melanoma and melanocytic lesions, and 23 with sarcomas. RESULTS Of 58 lymphoscintigraphy procedures, sentinel lymph nodes were identified in 52 (90% success rate). Using the combination of intraoperative blue dye injection and lymphoscintigraphy, the success rate was 95% (55/58). Metastatic disease was found in 14 sentinel lymph nodes (13 patients with melanoma and melanocytic lesions, and 1 patient with rhabdomyosarcoma). CONCLUSION We have found that lymphoscintigraphy with SLNB is an effective method to identify patients who may benefit from more extensive lymph-node dissection and to identify those patients who are unlikely to benefit from further lymph-node exploration.

Abstract
Melanoma is rare in children and young adults. The incidence is rising yearly in this population. The clinical features of the disease in the pediatric population have been well documented through single-institution experiences and population-based analyses. Still, our understanding of the etiologic factors in the majority of children remains unclear, and diagnosis of melanoma remains challenging in certain cases. Because of its rarity, the staging, management and treatment of melanoma in this population is adopted from adult guidelines. In this review, we provide information on the epidemiology, clinical presentation, staging, prognosis and management of melanoma in children and young adults.

Abstract
The diagnosis and treatment of children and adolescents with cancer has a tremendous and lasting effect on the patients, their families, and other individuals in their social network. It carries a host of psychological and behavioral ramifications, from questions of mortality to changes in levels of functioning in multiple domains. In this review the authors address the psychosocial and treatment-related issues that arise in children with cancer, with attention to the adjustment to cancer at different developmental stages, mood and anxiety issues, treatment-related psychiatric sequelae, and the challenges faced by childhood cancer survivors.

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
Sentinel lymph node (SLN) biopsy has become integral in the staging of patients with melanoma, and entails detailed histologic examination with immunohistochemistry. Reverse transcriptase-polymerase chain reaction (RT-PCR) for tyrosinase transcripts has been used to increase sensitivity but requires a dedicated piece of tissue that does not undergo histologic examination. We developed a nested RT-PCR assay for tyrosinase applicable on paraffin-embedded tissue and applied this to a series of SLNs from pediatric patients with melanoma. Thirty-six SLNs from 4 females and 4 males were included in the study. Eight lymph nodes with reactive changes were included as controls. SLNs were examined histologically and immunohistochemically for S100, tyrosinase, and MART1. Seven patients had between 1 and 4 morphologically-positive SLNs and one patient had negative SLNs (HISTO+; 12/36, 33%). Three lymph nodes were excluded from molecular analysis owing to inadequate RNA, and 29 of the remaining 33 nodes were positive (MOL+; 88%). All patients had at least 1 SLN positive by RT-PCR. Twelve were HISTO+/MOL+; 17 were HISTO-/MOL+; and 4 were HISTO-/MOL-. All control lymph nodes were negative for tyrosinase transcripts. The application of RT-PCR for tyrosinase to paraffin-embedded tissue significantly increased the number of positive SLNs and upstaged one patient from negative to positive. The prognostic implications of such findings require further investigation, especially in the pediatric age group. Nonetheless, this technique provides a useful tool to determine the clinical significance of RT-PCR positivity in melanoma SLNs.

Abstract
The diagnosis and treatment of children and adolescents with cancer has a tremendous and lasting effect on the patients, their families, and other individuals in their social network. It carries a host of psychological and behavioral ramifications, from questions of mortality to changes in levels of functioning in multiple domains. In this review the authors address the psychosocial and treatment-related issues that arise in children with cancer, with attention to the adjustment to cancer at different developmental stages, mood and anxiety issues, treatment-related psychiatric sequelae, and the challenges faced by childhood cancer survivors.

Abstract
IMPORTANCE OF THE FIELD Although most children with cancer are cured, there remain significant limitations of standard treatment, most notably chemotherapy resistance and non-specific toxicities. Novel immune-based therapies that target pediatric malignancies offer attractive adjuncts and/or alternatives to commonly employed cytotoxic regimens of chemotherapy or radiotherapy. Elucidation of the principles of tumor biology and the development of novel laboratory technologies over the last decade have led to substantial progress in bringing immunotherapies to the bedside. AREAS COVERED IN THIS REVIEW Current immunotherapeutic clinical trials in pediatric oncology and the science behind their development are reviewed. WHAT THE READER WILL GAIN Most of the immune-based therapies studied to date have been well tolerated, and some have shown promise in the setting of refractory or high-risk malignancies, demonstrating that immunotherapy has the potential to overcome resistance to conventional chemotherapy. TAKE HOME MESSAGE Some immune-based therapies, such as ch14.18 and MTP-PE, have already been proven effective in phase III randomized trials. Further studies are needed to optimize and integrate other therapies into standard regimens, and to test them in randomized trials for patients with childhood cancer.

Abstract
Pediatric melanoma is rare but increasing in incidence. Because early diagnosis and treatment improves prognosis, clinicians need to include it as a possible diagnosis when evaluating a pigmented lesion in a pediatric patient. Some risk factors for melanoma include xeroderma pigmentosum, giant congenital melanocytic nevi, dysplastic nevus syndrome, atypical nevi, many acquired melanocytic nevi, family history of melanoma, and immunosuppression. Definitive treatment is with surgical excision. Adjuvant therapies such as chemotherapy, immunotherapy, and radiation therapy can be used in advanced cases.

Abstract
Malignant melanoma is rare in pediatrics, and therapies for patients with disseminated disease have not been well studied. This report describes our experience with the use of high-dose interleukin 2 (aldesleukin, IL-2) in a 2-year-old child with metastatic melanoma and describes our approach for the administration of this agent to young patients.

Abstract
The family practitioner, pediatrician, and dermatologist all have potential roles in the primary prevention, diagnosis, and treatment of localized thin melanomas. Surgical and medical oncologists are often involved when controversy arises over the nature of the skin lesion or whether sentinel lymph node (SLN) biopsies and adjuvant therapy are to be contemplated. This overview of melanoma will deal with the primary and nodal pathology, surgery, and medical therapy of melanoma in pediatric, adolescent, and young adult patients--and will raise areas of controversy that are only recently being addressed in databases of cases from this age group.

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.

Abstract
BACKGROUND Melanoma occurring during childhood and adolescence is rare. Although a few limited studies suggest that the prognosis of childhood melanomas is similar to those in adults, and is dependent on the initial stage of the tumor, there is controversy with respect to the biologic behavior of childhood melanomas. Spitzoid melanoma is a subtype of melanoma with distinct clinical and histopathologic features. The prognosis of spitzoid melanoma in children, despite metastasis, has been suggested to be better than that observed in adults; however, this assertion remains controversial. Whereas a number of spitzoid melanomas with regional lymph node metastasis with no further progression have been reported, cases leading to widespread metastasis and fatal outcomes are also well documented. METHODS A retrospective review of the literature was conducted between 1949 and 2006. A total of 82 cases of spitzoid melanoma with regional and/or widespread metastasis that occurred in children, 17 years of age and under, were selected for the analysis. RESULTS The 5-year survival rate in children diagnosed with metastatic spitzoid melanomas between 0 and 10 years of age was 88% compared with 49% in those between 11 and 17 years of age. CONCLUSIONS The findings support the notion that younger age (< or =10) may be associated with longer survival in children with metastatic spitzoid melanomas.

Abstract
Purpose This study examines the demographics, presentation, and outcomes of children and teenagers with melanoma using a US hospital-based oncology database. Patients and Methods Data from the National Cancer Data Base from 1985 through 2003 were examined for demographics, presentation, and survival of patients aged 1 to 19 years, as well as a comparison group of patients aged 20 to 24 years. Two-sided linear and Pearson χ2 tests were calculated to examine associations. Proportions were compared using two-sided z tests. Five-year overall observed survival was evaluated using the Kaplan-Meier method and the log-rank test. Cox proportional hazards regression was used to estimate risk of mortality. Results Of 3,158 patients aged 1 to 19 years, 96.3% had cutaneous melanoma, 3.0% had ocular melanoma, and 0.7% had an unknown primary tumor. Cutaneous melanoma in patients aged 1 to 19 years was more common in girls (55.5%) and patients older than 10 years (90.5%). The demographics and presentation of cutaneous melanoma were age related; younger children were significantly more likely to be nonwhite and male and more likely to present with a head and neck primary tumors and with regional or distant metastases (linear χ2, P < .001 for sex, race, and extent of disease). Poorer survival was associated with higher stage and younger age. In contrast to patients aged 20 to 24 years, survival was not related to thickness in patients aged 1 to 19 years with localized invasive melanoma. Conclusion Melanoma in children and teenagers differs from melanoma in young adults in demographics, presentation, and survival. Further investigation is warranted to elucidate possible biologic correlates of the unique aspects of melanoma in children and teenagers.

Abstract
OBJECTIVES The objectives of this study were to review our experience with pediatric melanoma of the head and neck and discuss proper diagnostic protocols and suggest a possible treatment algorithm. STUDY DESIGN The authors conducted a retrospective chart review of patients under the age of 18 who underwent treatment for melanoma of the head and neck at a tertiary care university hospital. RESULTS Six patients were identified in the last 25 years at our institution. Four patients had melanomas in the auricle, one in the cheek, and one in the forehead. All occurrences identified presented in the past 7 years. All were treated with wide local excision. Three patients received sentinel lymph node biopsy, one received a neck dissection after identification of positive sentinel nodes, and two patients received postoperative interferon therapy. No surgical complications were reported. At the time of this submission, no patients were found to have recurrence of the disease. CONCLUSIONS Pediatric melanoma of the head and neck may be managed effectively using current techniques used in treating adult patients. The use of sentinel lymph node biopsy is recommended when the depth of invasion cannot be determined from original biopsy, the original pathologic diagnosis is ambiguous, or depth of invasion from biopsy is sufficient to warrant its use. In addition, the use of adjuvant interferon alpha-2b is recommended in patients at high risk for recurrence.

Abstract
BACKGROUND Melanoma comprises less than 3% of all cancers seen in children. Sentinel lymph node biopsy (SLNBX) is an important predictor of outcome in adult melanoma and has not been widely used in pediatrics. Furthermore, adjuvant interferon has only been rarely used in childhood high-risk disease. OBJECTIVE To review our experience with high-risk melanoma, the feasibility of SLNBX and the tolerance of high-dose interferon (HDI) therapy. METHODS We retrospectively reviewed the medical records of patients with the diagnosis of cutaneous melanoma at our center over a 10-year period. RESULTS Eleven patients were identified (median age of 12 y). Six of 10 patients who underwent SLNBX had disease in the lymph nodes and no complications from this procedure were observed. After complete lymph node dissection in these 6 patients, 1 developed wound infection and 2 had chronic lymph edema. Five patients were treated with adjuvant HDI of whom 2 patients required dose modification due to myelosuppression and liver toxicity. After a median follow-up of 26 months, 10 out of 11 patients are in remission. CONCLUSIONS SLNBX is feasible and safe in pediatric melanoma and offers the potential to identify patients at high risk for disease progression who could benefit from HDI.
