Giant Congenital Melanocytic Nevus (GCMN) causes a significant cosmetic defect associated with possible psychosocial problems in these patients, and mainly threatens these patients from the point of view of the possibility of the risk of malignant transformation. Currently, there is no well-defined strategy for how to approach these patients. The treatment strategy is different for each patient and it is important to consider it individually. In this case report, we present a girl in early adolescence with a giant congenital melanocytic nevus on the dorsum of the leg extending to the distal lower leg, in which we chose to apply an expander with later surgical removal of this lesion followed by the application of MatriDerm® (MedSkin Solution Dr. Suwelack AG, Billerbeck, Germany) in combination with an autologous skin graft. Factors important when considering a treatment strategy include the possibility of the presence of high-risk phenotypic features associated with malignant transformation, among which the size is greater than 20 cm in diameter, the localization of the lesion, the presence of multiple lesions, irregular morphology and, last but not least, the histological result. Other important facts when deciding on further treatment include considering the possibility of psychosocial impact and cosmetic deformity in these patients.
