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
Cancer during pregnancy has been associated with (pathologically) small for gestational age offspring, especially after exposure to chemotherapy in utero. These infants are most likely growth restricted, but sonographic results are often lacking. In view of the paucity of data on underlying pathophysiological mechanisms, the objective was to summarize all studies investigating placental pathology related to cancer(treatment). A systematic search in PubMed/Medline, Embase (OVID) and SCOPUS was conducted to retrieve all studies about placental pathology in cancer during pregnancy or after cancer treatment, published until August 2020. The literature search yielded 5784 unique publications, of which 111 were eligible for inclusion. Among them, three groups of placental pathology were distinguished. First, various histopathologic changes including maternal vascular malperfusion have been reported in pregnancies complicated by cancer and after cancer treatment exposure, which were not specific to type of cancer(treatment). Second, cancer(treatment) has been associated with placental cellular pathology including increased oxidative damage and apoptosis, impaired angiogenesis and genotoxicity. Finally, involvement of the placenta by cancer cells has been described, involving both the intervillous space and rarely villous invasion, with such fetuses are at risk of having metastases. In conclusion, growth restriction is often observed in pregnancies complicated by cancer and its cause can be multifactorial. Placental histopathologic changes, cellular pathology and genotoxicity caused by the cancer(treatment) may each play a role.

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
We describe a rare case of transplacental-transmitted maternal melanoma to the placenta and foetus during the second pregnancy of a 28-year-old woman. She was aware of a greyish-brown nodular lesion on the right gluteus during her first pregnancy. On histological examination, this lesion resulted to be an amelanocitic melanoma. Breast metastases occurred during her second pregnancy, 18 months after the surgical excision; an emergency Caesarean section performed for the recrudement of her clinical conditions confirmed widespread metastases to the liver, spleen and peritoneum. The patient died 2 weeks after delivery. The newborn, at 3 months of age, presented metastases secondary to maternal melanoma, which were resistant to chemotherapy. The disease regressed spontaneously and the child is now 24 months, alive in complete remission.

Abstract
The purpose of this paper was to update and analyse all the reported cases of placental metastasis. These tumours are rare and seem to complicate aggressive or disseminated malignant melanomas, leukaemias, breast cancers and lung cancers. Maternal prognosis is poor. The risk factors of cancer in the newborn are unknown. In a pregnant woman with a history of malignancy, a systematic histological examination of the placenta for evidence of metastasis is required. Close observation and follow-up of the infant has to be recommended, especially in case of placental involvement. To estimate the incidence of placental metastases and to improve knowledge of their natural history, the creation of registries of malignancies associated with pregnancy is required.

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
Metastasis of maternal malignant tumor to the products of conception is a rare event. Melanoma is the most common maternal malignant tumor to metastasize to the placenta and the fetus. We report the case of a 28-year-old woman with melanoma during pregnancy. At parturition, histologic evaluation of the placenta revealed metastatic melanoma, and multiple organ metastasis developed. The infant was free of disease. Metastasis to products of conception portends a poor prognosis for the mother. To our knowledge, this report is the first of a patient with melanoma metastasis to the placenta to survive more than 7 months after parturition. As caretakers of patients with melanoma, dermatologists are in a position to coordinate and direct the care and follow-up treatment of affected patients.

Abstract
Cancer in pregnancy is not rare, and the possibility of transmission of malignancy from mother to child, while infrequent, represents a clinical challenge for the primary pediatric hematologist-oncologist. The authors summarize all reported cases of vertically transmitted cancer and review other reported cases of person-to-person transfer of malignancy. As these cases represent a unique physiologic model of tumor transplantation, the biology of cancer transmission is discussed and provisional guidelines are given for the screening of infants born to women with cancer.

Abstract
PURPOSE Although metastases to the fetus via the placenta are rare, melanoma is the most common culprit. When it occurs, maternally derived melanoma metastasis in the infant is almost invariably fatal. PATIENTS AND METHODS This article reviews current guidelines for placental evaluation in pregnant women with metastatic melanoma and presents surveillance recommendations for their infants. Comprehensive literature reviews were performed on melanoma in pregnancy and melanoma metastasis to the placenta and fetus. The use of interferon alfa in the pediatric population was also reviewed. A comprehensive search of the MEDLINE database (1966 to 2002) was performed. Articles were reviewed and additional references were obtained from the bibliographies. Translation of non-English articles was performed, and authors of previous publications were contacted. RESULTS Eighty-seven patients with placental or fetal metastasis were identified. Twenty-seven occurrences were attributed to melanoma (31%). The fetus was affected in six of 27 melanoma patients (22%), with five of six infants dying of disease. The use of high-dose interferon alfa adjuvant therapy in pediatric patients has not been reported. CONCLUSION The placentas of women with known or suspected metastatic melanoma should be carefully examined grossly and histologically by pathologists. With placental involvement, fetal risk of melanoma metastasis is approximately 22%. Neonates delivered with concomitant placental involvement should be considered a high-risk population. The risk-benefit ratio of adjuvant treatment for a potentially affected infant should be carefully weighed.

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
AbstractAcute leukemia has a high concordance rate in young identical twins and in infants this is known, from molecular analysis, to reflect an in utero origin in one twin followed by prenatal metastasis to the other twin via intraplacental anastomoses. The situation in older twins with leukemia has been less clear. We describe a pair of identical twins who were diagnosed with a T-cell malignancy at 9 and 11 years of age, one with T-cell non-Hodgkin's lymphoma and the other with T-cell acute lymphoblastic leukemia. Leukemic cells from the twins shared the same TCRβ gene rearrangement with an identical 11 bp N region. The most plausible interpretation of this result is that these malignancies were initiated in one twin fetus in utero, in a single T-lineage cell that had stable bi-allelic TCRβ rearrangements. Progeny of this cell then spread to the other twin before birth via shared placental vasculature. This was then followed by a 9- and 11-year preleukemic latent period before clinical disease manifestation as leukemia or lymphoma. This result has considerable implications for the etiology and natural history of pediatric leukemia.

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
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
Six patients with prepubertal malignant melanoma are presented. Three were metastatic. One was congenital in a giant pigmented nevus. A second was found at 6 mo of age to have metastatic lesions. All were treated aggressively and had a favorable outcome. Aggressive treatment, once malignant melanoma is diagnosed, is recommended. Prognosis does not differ markedly from similar lesions in adults.
