Résumé
Malignant melanoma is a rare neoplasm in the pediatric age group. One of the main risks factors is represented by the presence of a high number of melanocytic nevi. Sun exposure in pediatric age represents a predictor of melanocytic nevi number in the adult age and there is a direct correlation between the presence of melanocytic moles in early childhood and the development of many nevi in adults, suggesting that a high number of nevi in childhood should be considered as a predictor of melanoma development during adult life. The predominance of dermoscopic types of melanocytic nevi varies according to the individual's age and depends on endogenous or exogenous signaling, suggesting different pathways of nevogenesis. We evaluated the total amount of melanocytic nevi of pediatric patients and their prevalent dermoscopic pattern. We investigated the reasons for dermatological examination, pointing out the role of older parents' populations in the decision to refer to a dermatological consultant. We performed a prospective observational study on 295 pediatric outpatients consecutively enrolled from July 2018 to July 2019. Descriptive and inferential statistical analyses were performed using logistic and linear regression. 49% of children were characterized by less than 10 nevi, 45% of children by a number of nevi between 10 and 30, whilst 17 patients (5%) had a number of nevi between 30 and 50. The most prevalent dermoscopic pattern was the globular one. An older parenting age was correlated with an autonomous reason for referral and a later first visit. Our data agreed with previous suggestions demonstrating a strong influence of latitude, sun exposure and ethnic background in the development of the number of nevi. To our knowledge, this is the first study, which evaluated the reasons for dermatological examination and the role of older parents' populations in the decision to refer to a dermatological consultant.
