Abstract
Eruptive melanocytic nevi (EMN) is a phenomenon characterized by the sudden onset of nevi. Our objective was to compile all published reports of EMN to identify possible precipitating factors and to evaluate the clinical appearance and course. We conducted a systematic bibliographic search and selected 93 articles, representing 179 patients with EMN. The suspected causes were skin and other diseases (50%); immunosuppressive agents, chemotherapy or melanotan (41%); and miscellaneous, including idiopathic (9%). The clinical manifestations could largely be divided into two categories: EMN associated with skin diseases were frequently few in number (fewer than ten nevi), large, and localized to the site of previous skin disease, whereas those due to other causes presented most often with multiple small widespread nevi. In general, EMN seem to persist unchanged after their appearance, but development over several years or fading has also been reported. Overall, 16% of the cases had at least one histologically confirmed dysplastic nevus. Five cases of associated melanoma were reported. We conclude that the clinical appearance of EMN may differ according to the suggested triggering factor. Based on the clinical distinction, we propose a new subclassification of EMN: (1) widespread eruptive nevi (WEN), with numerous small nevi, triggered by, for example, drugs and internal diseases, and (2) Köbner-like eruptive nevi, often with big and few nevi, associated with skin diseases and most often localized at the site of previous skin disease/trauma. The nature of the data precluded assessment of risk of malignant transformation.

Abstract
There are at least two pathways driving cutaneous melanoma; one is linked to an inherent melanoma susceptibility to nevi development and the second to environmental cumulative ultraviolet light exposure. In this study, we examined the relation between nevus density, accrued sun damage and the site of primary melanoma excision. In a series of 888 consecutive cutaneous melanoma patients, melanomas appearing in skin areas with a high relative nevus density were most prominent in men, with an elevated nevus count, at sites without solar elastosis, but with an epidemiological history of previous sunburn. The present study associates melanoma development to sites with high nevus density. Our study supports more careful surveillance of body areas with increased nevus density in patients with high total body number of nevi, especially when they report a history of sunburns at these sites.

Abstract
Pediatric organ transplant recipients (POTRs) are at risk of developing malignancies due to a combination of immunosuppression, impaired DNA damage repair, and infection with oncogenic viruses. The most commonly developed malignancies in this population are skin cancers, which include nonmelanoma skin cancer, melanoma, Kaposi's sarcoma, and anogenital carcinoma. The literature shows that skin cancers account for 13% to 55% of all cancers that occur after transplantation. Given the increasing number and life expectancy of POTRs, prevention and management of skin cancer in these patients is essential, but there is a substantial knowledge gap in our understanding of the differences in skin cancer development, prevention, and management between POTRs and adult organ transplant recipients (AOTRs), for whom more data are available. Substantial differences have been observed in the patterns of malignancy development between POTRs and AOTRs, and data specific to pediatric populations are needed. The objective of this review is to provide updated information on posttransplantation skin cancer development in POTRs, including epidemiologic research on transplant patients and disease development, medication management, surveillance, and education efforts.

Abstract
This systematic review provides information on malignant melanoma as second malignant neoplasm (SMN) after childhood cancer and evaluates its risk factors. Study reports describing incidences of SMN and malignant melanoma as SMN in a population of childhood cancer survivors (CCS) were included. Of 151,575 CCS, 4,010 (2.6%) children developed an SMN, 212 of which were melanoma (5.3% or 0.14% of all CCS). The following risk factors for malignant melanoma as SMN were identified: radiotherapy, or the combination alkylating agents and anti-mitotic drugs. Melanomas are most frequently observed after Hodgkin disease, hereditary retinoblastoma, soft tissue sarcoma, and gonadal tumors.

Abstract
A 22-year-old white man without a personal or family history of atypical nevi had received chemotherapy for pre-B-cell acute lymphocytic leukemia at age 17 that included L-asparaginase, prednisone, methotrexate, mercaptopurine, daunorubicin, and cytoxan. Two to three months after completing maintenance chemotherapy, the patient reports he developed many moles, which remained stable for approximately 2 years. Upon examination, two dark, atypical appearing plaques with irregular borders and numerous pink papules of varying shapes and sizes were noted on his chest, back, and abdomen. Histology of specimens of both types of lesions revealed three moderately atypical compound dysplastic melanocytic nevi and three in situ melanomas. The lesions with only features of dysplastic nevi exhibited dermal fibrosis, cytologic atypia, junctional shoulders, lentiginous spread, and focal pigmentation. The lesions with in situ melanomas in addition demonstrated pagetoid spread, extension down adnexal structures, and more severe cytologic atypia. Malignant melanoma has been associated with chronic immunosuppression, and benign nevi have been reported to erupt after chemotherapy. We report an occurrence of multiple eruptive dysplastic nevi and in situ melanomas appearing shortly after completion of chemotherapy.

Abstract
The induction of multiple melanocytic nevi in children after chemotherapy has been documented in the literature. This situation apparently has more to do with the state of immunosuppression that is produced than with any specific agent used. We present the case of a 12-year-old girl who presented with multiple plantar melanocytic nevi after multidrug chemotherapy for acute lymphocytic leukemia. None of the lesions showed any alarming clinical signs. Although the degeneration of post-chemotherapy melanocytic nevi to melanoma has not been documented in any of the cases described, the presence of a high number of melanocytic nevi is an accepted risk factor for melanoma; thus, close clinical follow-up of these patients seems advisable.

Abstract
Excess melanocytic nevi have been reported in several groups of immunosuppressed patients, including organ transplant recipients. We report the case of a 16-year-old transplant recipient whose post-transplant melanocytic nevi decreased in size and color after graft rejection and interruption of immunosuppressive therapy. This case may represent a visual example of an effective immunosurveillance system against melanocytic nevi.

Abstract
The sudden eruption of atypical and benign melanocytic nevi has been associated with a number of disease states and primary skin conditions. Most case reports and series of patients have linked eruptive nevi with blistering skin disease or immunosuppression. Subsets of patients in the immunosuppressed category have remarkably increased numbers of nevi on the palms and soles. We describe a case of multiple eruptive nevi of the palms and soles in association with immunosuppression, and the potential underlying mechanisms promoting such nevogenesis are explored. Although both the absolute number of nevi and presence of dysplastic nevi have been correlated with an increased relative risk of melanoma, actual risk of melanoma in patients with eruptive nevi is unknown.

Abstract
BACKGROUND Organ transplant recipients taking immunosuppressants are at increased risk of skin cancer. Although several studies have been devoted to adult transplant patients, few data are available on the long-term skin malignancies following pediatric organ transplantation. OBJECTIVE The objective of this study was to present the current state of knowledge on skin malignancies in patients who received their graft during childhood. METHODS This study reviews data from the literature and includes our personal experience. RESULTS Skin cancer is the most frequent malignancy following pediatric renal transplantation and the second most common after pediatric nonrenal transplantation. Skin cancers mainly include squamous and basal cell carcinomas. The occurrence of skin cancer in transplanted children is an extremely rare event during childhood. By contrast, skin carcinomas develop in early adulthood at an average age of 27 years. Other reported skin malignancies include anogenital carcinomas and melanoma. Cutaneous forms of Kaposi's sarcoma are exceptional in children. CONCLUSION The increased risk of skin cancer following pediatric transplantation justifies prevention and adequate education of children and their parents concerning sun avoidance and protection.

Abstract
Eruptive nevi have been reported after renal allograft transplantation, particularly in children and adolescents, and immunosuppression has been suggested to favor both benign and malignant melanocyte proliferation. In this study, we describe the dermoscopic features of eruptive melanocytic nevi in 10 children, adolescents, and young adults with renal allografts in whom multiple melanocytic nevi developed during a short period after transplantation. Dermoscopy of the eruptive pigmented lesions revealed a peripheral rim of brown globules. This rim of peripheral globules was present in 80% of the patients with eruptive nevi and in most of the lesions of the same patient. The other standard dermoscopic criteria for melanocytic nevi were normal. In our study, we confirm previous reports concerning the development of eruptive nevi in children and adolescents receiving immunosuppressive therapies. In particular, we showed by dermoscopy the presence of a characteristic symmetrical rim of peripheral brown globules. This finding is consistent with the hypothesis that a symmetrical peripheral rim of globules may indicate rapid enlargement of melanocytic lesions. Moreover, we have identified a new group of patients characterized by this dermoscopic feature. These patients are children, adolescents, and young adults with renal allografts receiving immunosuppressive therapy and it is plausible that this dermoscopic characteristic may be found in eruptive nevi developed in association with immunosuppression from any cause.

Abstract
In several studies from northern Europe, north America and Australia, melanocytic nevi are correlated with pigmentary traits and with intense sun exposure in a way similar to malignant melanoma. However, it is unclear if these data can be extrapolated to populations in other geographic locations and with different prevalent phenotypes. Our study was conducted among schoolchildren aged 13-14 years in 16 Italian cities. The parents of 3,127 children of a total of 3,160 (99%) consented to our study. A structured questionnaire was used to collect information about sun exposure and lifetime history of sunburns. Children were also examined by trained dermatologists to assess pigmentary traits and to make a count of melanocytic nevi. The median nevus density was higher among boys than girls. Areas that are usually chronically exposed to the sun exhibited a higher density of nevi compared to intermittently and rarely exposed areas. A higher density of nevi was found in children with lighter skin, blond hair and blue eyes. Red-haired children had a remarkably lower nevus density compared to the other color categories. The density of nevi increased with an increased number of reported episodes of sunburns. The results concerning nevi >/=6 mm in diameter paralleled those obtained for the total nevus density. However, at variance with total nevus density, a significant relation was also observed between larger nevi and freckling. Our study confirms that, in Italian schoolchildren, there is a relation between pigmentary traits, history of sunburns and the density of melanocytic nevi. Melanocytic nevi and malignant melanoma share a similar risk factor profile.

Abstract
BACKGROUND Skin diseases are frequent in organ transplant recipients, but studies concerning children are sparse. OBJECTIVE We assessed skin diseases in children who had received organ transplants. METHODS A total of 145 children referred to our dermatologic consultation were studied. RESULTS Steroid-induced striae distensae and acne occurred only in adolescents; severe cyclosporine-related side effects were more frequent in younger children. The most common findings were warts (53.8%), tinea versicolor (14.5%), herpes simplex/zoster (9.6%), molluscum contagiosum (6.9%), and impetigo contagiosum and folliculitis (6.2%). Other notable disorders included a diffuse hyperpigmentation with a "dirty" appearance of the skin, pyogenic granulomas, melanocytic nevi proliferation, and skin tags. Two of 20 further adult patients who received transplants during childhood had squamous cell carcinomas. CONCLUSION Children who have received organ transplants frequently present side effects of immunosuppressive drugs and infectious diseases. Most disorders are related to the age of the patients rather than to the length of immunosuppression, whereas others are favored by the reinforcement of immunosuppression. Skin cancers were not encountered, but the risk of carcinomas in early adulthood should be considered.
