A Case of Acral Lentiginous Nevus / 대한피부과학회지

ABSTRACT

Acral lentiginous nevus(ALN) is a new disease entity recently proposed by Clemente et al in 1995. The main histopathological features of ALN are characterized by elongation of the rete ridges, lentiginous proliferation of melanocytes at the dermo-epidermal junction, the presence of melanocytes within the upper epidermis, poor or absent lateral circumscription of the intraepithelial melanocytes and, in the dermis, fibroplasia, vascular neogenesis, and lymphoid infiltration, which enable clinicians to distinguish these nevi from ordinary nevi and melanoma. We, herein, report a case of ALN of plantar skin with unique histopathological characteristics.
