PARTICULARITIES OF MELANOCYTIC NEVUSES OF CHILDREN

Vinnitsa National Medical University named after M.I. Pirogov, Vinnytsia,
Ukraine

Objective. Determination of clinical and morphological features of the recurrent course of melanocytic skin lesions in children.
Methods. The study is based on the data analysis of 468 histological protocols of removing nevi taken from the archives of «Vinnytsia Regional Pathological Bureau of the Vinnytsia Regional Council» (Ukraine) during the whole period of the study (from 2018 to 2020).
Results. In general, the terms between the primary surgical removal / «self-removal» of the pigmented formation before the recurrence of melanocytic nevi made up 3-6 months. Melanocytic nevi recurrences in children occurred in different areas of the skin, but most often on the trunk (44.44%) and scalp and neck (27.78%). A typical dermatoscopic sign of pigmented nevi recurrences was the presence of scar tissue on the periphery of the lesion. The confines of a recurrent pigmented tumor on dermatoscopy were not clearly symmetrical.
Conclusion. The existing difference in the morphological structure of different types of melanocytic nevi explains the low frequency of clinical and histological diagnoses in recurrent pathology in childhood; the possibility of atypical cells presence of melanocytic origin in the scar area necessitates differential diagnosis in case of the skin melanoma recurrence, especially in cases of histological verification absence of the primary melanocytic lesion.
