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
Acral lentiginous melanoma of the foot is a relatively rare but often very aggressive variant of melanoma. More commonly identified in patients with darker skin, diagnosis of the lesions is often delayed because the area is not routinely examined by patients or primary care physicians. In addition, these lesions often mimic other entities, including vascular lesions and infections. Greater awareness of this entity and performing appropriate biopsies will result in more timely diagnoses and improved survival.

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
Melanocytic lesions of uncertain malignant potential (MUMP) is a term which is useful in identifying melanocytic tumours where the distinction between benign and malignant is a histological problem. Sentinel node biopsy is recognised to provide unmatched prognostic information in melanoma patients, but has recently been advocated for diagnostic purposes in MUMP. We present the case of a seven-year-old girl who presented with a six-month history of a changing pigmented lesion on her left upper arm. Excision biopsy not only showed a melanocytic lesion with some spitzoid features but also marked atypia making it appropriate to use the term MUMP. Sentinel node biopsy was undertaken. This case demonstrates that sentinel node biopsy can be performed safely in children. Given the low morbidity of the procedure we advocate that this technique should be considered in this difficult diagnostic situation to further the management of these patients.

Abstract
BACKGROUND/PURPOSE Childhood melanoma is rare but increasing in incidence. Its management relies on early diagnosis. The purpose of this study is to discuss surgical indications of nevi and diagnosis of melanoma in a pediatric surgical unit. METHODS Data relative to the patients who underwent removal of nevi in our pediatric surgical unit from 1999 to 2005 were reviewed to identify indications, histology, and melanoma occurrence. RESULTS The most frequent indication was atypical nevus. Compound nevus was the most common finding, followed by congenital and Spitz nevi. Melanoma was diagnosed in 3 excised nevi, and in 1 case it occurred as a metastatic disease. CONCLUSIONS Our data showed a pattern of indications for surgery similar to that described in the literature, with a high detection rate of melanoma, nonetheless showing that some rare conditions may delay diagnosis.

Abstract
Childhood melanoma is a rare but potentially fatal disease that is important to include in the differential diagnosis of any pigmented lesion in a child. The best prognosis is achieved with early diagnosis and definitive surgical excision. Adjuvant chemotherapy and immunotherapy are options for those with more advanced tumors. Melanoma in children must be treated as aggressively as in adults because childhood melanoma may be equally devastating.

Abstract
BACKGROUND Sentinel lymph node (SLN) status is the strongest predictor of survival in adult melanoma. However, the prognostic value of SLN status in children and adolescents with melanoma is unknown. METHODS Records of 327 patients aged 12 to 86 years undergoing SLN biopsy for melanoma or other melanocytic lesions were reviewed. A literature search identified additional patients younger than 21 years undergoing SLN biopsy for the same indications and these patients were combined with our series for meta-analysis. RESULTS Sentinel lymph node metastases were found in 8 (40%) of 20 patients aged 12 to 20 years compared with 55 (18%) of 307 adults (P < .05). Median follow-up was 35 and 17 months for the groups, respectively. Sentinel lymph node-positive pediatric patients did not recur, whereas 14 (25%) adults recurred within this period. Of the 55 adults, 5 (9.1%) have died of disease. Of the combined SLN-positive children and adolescents from the literature (total n = 25), only a single (4%) child recurred at 6 months. The difference in survival for adult and pediatric patients was significant. CONCLUSION Pediatric patients have a higher incidence of SLN metastases than adults yet have a lower incidence of recurrence. Sentinel lymph node status does not predict early recurrence in pediatric patients with melanoma or atypical Spitz nevi.
