Balloon cell nevus in children: Report of three cases of the scalp and review

다국어 초록 (Multilingual Abstract)

Balloon cell nevus (BCN) is a histopathological variant of cutaneous acquired melanocytic nevi characterized by junctional and/or dermal nests of large cells with a clear and foamy cytoplasm which has rarely been described in children. Three cases of BCN firstly reported on the scalp in two pediatric patients are presented along with a literature review. Dermoscopy is particularly indicated in those pigmented lesions showing a yellowish hue, in ruling out in real time those disorders that may clinically be similar such as xanthogranuloma and sebaceous nevus, and to suggest the diagnosis of BCN. The final diagnosis, however, is established by histopathological examination.
