Abstract
Malignant melanoma, a rare skin cancer in children, primarily affects individuals over 10 years old. Giant congenital nevi, found in about 1% of newborns, increases the risk. However, the development of melanoma from a pre-existing giant congenital nevus diagnosed during the neonatal period is exceptionally rare. We present a case of congenital melanoma in a newborn, where nodules grew on an existing nevus on the baby's back. Literature on managing such cases was reviewed. This case highlights the importance of considering malignant transformation in congenital nevi and the challenges in their management. Due to limited reported cases over 80 years, conclusive findings on survival and treatment options are difficult to provide. Clinicians should report outcomes to develop a management algorithm for neonatal melanoma. Further studies are needed to enhance understanding of causes and treatment for patients with congenital giant hairy nevi and associated melanoma.

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
INTRODUCTION Neonatal and infantile malignant melanoma is rare. It may be difficult to diagnose and often carries a poor prognosis. MATERIAL AND METHODS We decided to review the data on congenital, neonatal and infantile malignant melanomas in order to understand their presentation (clinical, histological, molecular), diagnosis, management and outcomes. We performed a literature search of all cases of early-onset melanoma published in PubMed from its inception to March 2019 using the following keywords: "malignant melanoma" OR "melanoma" OR "pigmented nevus" OR "malignant pigmented" AND "infantile" OR "congenital" OR "children" OR "childhood" OR "infancy" OR "neonatal". Congenital melanoma associated with maternal-foetal transmission was not included in the study. RESULTS Sixty-five articles were selected and 85 cases were included in the study. Most patients were male (sex ratio: 1.6). The average age at diagnosis was 5.5 months (minimum-maximum: 0-24 months). The main site reported for congenital melanoma was the head-and-neck area and for neonatal and infantile melanoma the trunk. Half of all patients had a metastatic disease at the time of diagnosis. In metastatic cases, the prognosis was poor with the exception of patients undergoing complete excision of the tumour and metastases. The main treatment for cutaneous melanomas and operable metastasis was surgery, and secondarily, chemotherapy/immunotherapy. CONCLUSION Neonatal and infantile malignant melanoma are rarely reported and not well-documented. It is necessary to collect additional cases to improve our knowledge of this rare disease.

Abstract
Congenital and infantile malignant melanomas are rare and typically carry poor prognosis. The purpose of this article was to review the data on congenital and infantile malignant melanomas of the scalp in order to understand its presentation, diagnosis, management, and outcomes of congenital melanoma of scalp. We searched PubMed, CINAHL and Cochrane databases. Ten cases of congenital and 3 cases of infantile malignant melanoma of scalp were identified. The diagnosis was confirmed by biopsy and histological analysis for confirmation. The prognosis depends on the origin of disease (congenital melanocytic nevus, transplacental metastasis, or de-novo), tumor thickness, the presence of ulceration and/or necrosis, and anatomic site (scalp lesions having poor prognosis). The most commonly used treatment of the reported cases of congenital and infantile melanoma was surgical excision of the primary lesion. Further modes of treatment may be extrapolated from the treatment of childhood and adult melanomas. Congenital and infantile malignant melanomas are rare. Surgery is the mainstay of treatment. Prognosis of the condition remains poor.

Abstract
Congenital malignant melanoma (CMM) is a rare condition that is defined as malignant melanoma recognized at birth. CMM may develop in utero in one of three ways: (1) transmission by metastasis through the placenta from a mother with melanoma; (2) primary melanoma arising within a giant congenital melanocytic naevus (GCMN); (3) primary de novo cutaneous CMM arising in utero. CMM can be confused clinically and histologically with benign proliferative melanocytic lesions such as giant congenital nevi. We describe the case of a patient presenting a GCMN with proliferative nodules, clinically and dermoscopically resembling a CMM, demonstrating the importance of caution in making a diagnosis of MM and highlighting the possibility that benign lesions as GCMN can mimic a malignant melanoma in this age group.

Abstract
INTRODUCTION Congenital naevi (CN) vary greatly in size, macroscopic appearance and histology. There is a practical need to subdivide CN according to size, since size differences have a direct bearing on cosmetic and resultant psychological problems, and on therapeutic options, and probably on the chance of malignant transformation. In this review, we summarise the literature on size subgroupings of CN, with special focus on giant congenital naevi and their risk of malignant transformation. MATERIALS AND METHODS A Medline literature search from 1966 to October 2002 was performed. Only English-language studies focusing on CN in association with melanoma were included. The final strategy consisted of textwords and medical subject heading (MeSH) terms on small, medium, large and giant congenital naevi combined with the textwords classification, histology and melanoma. Additional manual cross-referencing was performed. We excluded articles that dealt only with aspects of treatments. RESULTS A wide variety of criteria for size subgrouping of CN has been put forward in the literature and precludes a direct comparison of reported data (Table 1). We identified 35 such articles in the world literature in which no less than seven different definitions of minimum size of a giant CN were employed. Histologically, it is difficult or even impossible to conclude that a naevus is congenital or acquired, especially in case of a small lesion, since the differences are not absolute (Table 2). Giant CN have an increased risk for malignant transformation, but the reported incidence rates have differed widely from one to 31% (Table 3). Reported melanoma incidence rates have derived from retro- and prospective studies, reviews and case reports, and compared with each other using different definitions. On top of this, patients in different age groups were reported, who were registered in different referral centers. CONCLUSION To allow comparison of study results from different centers, it is essential that the size subclassification of CN is based on standard and generally accepted criteria. We recommend defining GCN as a CN covering one percent body surface area in face and neck and two percent elsewhere on the body. Based on a review of the world literature, we recommend prophylactic excision of all CN, in close communication with patient and family and individualising treatment accordingly.

Abstract
Congenital malignant melanoma (MM) is an uncommon condition that is defined as MM recognized at birth. Its incidence is difficult to determine because of the small number of reported cases and because of problems associated with diagnosis. Generally, Spitz naevus and melanoma have many clinical and histopathological similarities, so it is difficult to differentiate between the two. We describe a rare case of congenital MM in which differential diagnosis from Spitz naevus was problematic. In addition, we review the literature and comment on the prognostic differences among the three types of congenital and infantile MM.

Abstract
Our series was comprised of 11 children age 10 years or younger (6 were younger than age 5) with primary cutaneous melanoma. All of the melanomas occurred de novo and all metastasized; one child died. In no instance was melanoma a clinical consideration, and in none did the histopathologist who first "signed out" the case make a diagnosis of melanoma. Despite the inability of clinicians and pathologists to diagnose correctly, with repeatability, melanomas that develop in children yet to be pubescent, those neoplasms, nonetheless, are melanomas and, therefore, criteria employed currently for diagnosis of melanoma, especially clinically, must be refined in order that they be applicable equally to melanomas in pre- and postpubescents. The vaunted ABCDs (Asymmetry, Border irregular, Color variability, Diameter >6.0mm) surely do not work for melanomas that appear in children who are prepubescent. Additionally, melanomas that occur in these children have distinctly different architectural and cytopathological features from those that arise in postpubescents, often being confused as they are by conventional microscopy with a Spitz's nevus. As a rule, melanomas in prepubescent children grow much more rapidly then those in adults but, like them, have the capability to disseminate widely and cause death.

Abstract
Congenital and infantile types of melanoma are uncommon conditions for which there are limited epidemiologic data. The number of reported cases is small with several ascribed etiologies. We review the literature and report the first documented case, to our knowledge, of pigment-synthesizing melanoma in an infant. Reported cases of congenital and infantile melanoma were identified and categorized on the basis of disease origin. Dermatopathologic specimens from an infant given a diagnosis of pigment-synthesizing melanoma are described. Disease arising from medium and large/giant congenital nevi was most common, whereas reports of de novo and transplacental disease were infrequent. Death of approximately 40% of patients was noted within 18 months of diagnosis. Male infants accounted for approximately 74% of cases. The most commonly affected anatomic sites were the head and neck. The prognosis for congenital and infantile melanoma is poor. The high incidence of head-and-neck involvement and male predominance for disease suggest dispositions for both anatomic disease localization and sex.

Abstract
There is general agreement that congenital giant pigmented nevi (CGPN) are precursors to malignant melanoma; however, the magnitude of the risk of malignant transformation is the subject of wide controversy. The goal of this study was to present the authors' experience with CGPN and more specifically their experience with the risk of malignancy. To identify the general features of CGPN a detailed retrospective chart review was performed at The Hospital for Sick Children in Toronto (1979 to 1994, n=84). There were 39 boys and 45 girls. The average size at presentation was 5.24% of the body surface area, and 36.9% of the nevus were located on the head and neck. An important finding was the high percentage of associated extra cutaneous disorders in patients with CGPN (23%) including a case of leptomeningeal melanocytosis. Tissue expansion was the most commonly used treatment modality. One case of malignant melanoma arising from CGPN was identified. To ensure that all cases of malignant melanoma were identified in this cohort, a questionnaire was sent to all plastic surgeons in Ontario (n=118), and data from the Ontario Cancer Registry were reviewed using the diagnostic codes for malignant melanoma and for pigmented nevus. One case of malignant melanoma was identified in all records. Thus CGPN poses a significant management challenge to the plastic surgeon and the risk of malignancy is low.

Abstract
BACKGROUND Malignant melanoma in childhood is rare. As a result, the biology and natural history of melanoma in this age group is still poorly understood. Although the majority of Spitz nevi are benign regardless of atypical features, a particular problem is the continued confusion of Spitz nevi with atypical features with melanoma and the lack of specific criteria for their distinction. The latter discrimination is perhaps not so difficult when Spitz nevi are minimally atypical; however, the greater the atypia, the more challenging is this discrimination. METHODS All cases of malignant melanoma referred to Children's Hospital (Boston, MA) and to one of the authors were examined during the period of 1959-1995. Criteria for inclusion in the study included: (1) age up to 15 years; (2) availability of microscopic slides; and (3) availability of demographic data. RESULTS There were 11 males and 12 females, ranging in age from 2 to 15 years (mean age, 9.4 years). Histopathologically, the 23 tumors were categorized into four subgroups: (1) small cell melanoma (5); (2) adult-like melanoma (6); (3) Spitz-like melanoma (3), and (4) atypical Spitz tumors (9). The small cell melanomas were notable for localization to the scalp, significant thickness, and fatal outcome. The adult-like melanomas resembled typical tumors occurring in adults. The one fatal Spitz-like melanoma was located on the neck of a 14-year-old male. Two tumors in this group metastasized to regional lymph nodes, but were not associated with further aggressive disease on follow-up despite treatment with surgical excision only. The atypical Spitz tumors were characterized by significant thickness and abnormal features including prominent cellularity and mitotic activity. CONCLUSIONS Anatomic site and cell type may be important prognostic factors in addition to tumor thickness for childhood melanoma, but these tumors require further study. In addition, the biologic potential of atypical Spitz tumors has not been characterized sufficiently.

Abstract
We describe a neonate with a highly atypical melanocytic proliferation that arose in a medium-sized congenital nevus, in association with multiple cutaneous satellite lesions and placental deposits. The patient's pathologic findings and benign clinical course to date raise the problem of diagnosis of congenital melanoma and the importance of clinical follow-up to determine the biologic behavior of severely atypical, histologically malignant proliferations in congenital melanocytic nevi.

Abstract
Six cases of malignant melanoma in children 14 years of age and younger are reported. The six cases were diagnosed among 850,000 consecutive skin biopsy specimens and consultation slides examined within a 32-year period. This series included an infant born with neurocutaneous melanosis, a child with malignant melanoma developing in a large congenital nevus at the age of 13 years, a superficial spreading malignant melanoma, Clark Level III, in a child with many dysplastic nevi, and three cases with primary nodular malignant melanoma, two of which showed histologic features of Spitz nevus. A review of the literature indicates that malignant melanoma in childhood is rare, and no large series have been investigated. It is not known whether the genetic and the environmental factors incriminated in the development of malignant melanoma in adults play a role in childhood melanomas. Data on the incidence of childhood melanoma in the population, the clinical and the histologic variations, and the prognosis are not adequate. A multiinstitutional study is needed to gather a large enough series to provide this information.

Abstract
Melanocytic nevi are common in children and adolescents, and the preponderance of these lesions are benign. Congenital melanocytic nevi, dysplastic nevi, and large numbers of common acquired nevi, however, may indicate an increased risk of malignant melanoma. With the exception, possibly, of giant congenital nevi, melanoma associated with these lesions generally occurs in adulthood. Nonetheless, some patients can be identified as being at increased risk for the development of melanoma during childhood. The poor prognosis associated with advanced melanoma and the curability of early lesions underscore the importance of prompt recognition of melanoma when it does occur in children. Furthermore, physicians who care for children are in a key position to decrease risk of melanoma throughout the lifespan by encouraging avoidance of excessive sun exposure during childhood.

Abstract
Twenty-three cases of congenital malignant melanoma have previously been reported. Here the authors report the first case of a congenital malignant melanoma arising in the eye. A newborn girl had a large pigmented ocular tumor, hepatomegaly, and multiple pigmented skin and choroidal lesions. The histopathologic diagnosis was of a malignant melanoma with hepatic metastases. The skin and choroidal lesions were considered to be congenital melanocytic nevi. The most plausible pathogenetic link between these two conditions was that the malignancy had arisen as a second-hit mutation within a choroidal congenital melanocytic nevus. Despite widespread metastases the baby, treated by surgery and chemotherapy, survives in good health, aged 2 years, 10 months.

Abstract
Four cases of malignant melanoma in children younger than 17 years of age are presented. Several preexisting conditions increase the risk of development of melanoma during childhood. These include giant congenital melanocytic nevi, the familial dysplastic nevus syndrome, and xeroderma pigmentosum. The role of small congenital lesions and sporadic dysplastic nevi in the development of melanoma in children is less clear. The signs and symptoms associated with melanoma in children are similar to those in adults, as are the histopathologic features, biologic behavior, and treatment of this tumor. The inadequacy of available therapy for metastatic melanoma underscores the necessity for the early diagnosis and prompt surgical treatment of melanomas in children.

Abstract
Histologic detection of micrometastatic melanoma in the placenta led to the clinical diagnosis in the mother. Metastases were present in the intervillous space and in villous stroma. The infant has survived and has no evidence of disease at one year of age. The mother died of metastatic disease 6 months post-partum. Literature review shows that only 25% of infants with placental metastatic melanoma succumb to the disease. In a review series of 16 cases, there are some maternal clinical factors which seem to have some bearing on the likelihood of fetal metastasis and death from disease. Features that are associated with an unfavorable fetal/infant prognosis are: maternal age less than 30 years, primiparity, leg primary site, disease onset greater than 3 years prior to pregnancy, node-1 metastatic status prior to pregnancy, M4 status in third trimester, birth at greater than 36 weeks' gestation, male sex. Extent of penetration of metastases into the villi does not have prognostic significance.

Abstract
This is the first case of congenital metastatic malignant melanoma to be reported in a premature infant whose mother did not have the disease. The possible relation of host immunity and multicentric origin to this rare occurrence is discussed. Exchange transfusion, using maternal blood, may improve survival in such cases.
