Abstract

Atypical Spitz`s nevus is a rare spitzoid melanocytic proliferations with an uncertain malignant potential. Atypical Spitz`s nevus have overlapping features of both Spitz nevi and spitzoid melanoma, and consequently, generate controversies with diagnosis and management. Herein, we report a case of atypical Spitz`s nevus developing on the lower right leg of a 46-year-old man. Histologically, the lesion shows numerous uniform nests of spindle cells and epithelioid cells in the dermis. The lesion had a high Ki-index, prominent cellular density, but not enough to consider a diagnosis of melanoma. The nevus was removed by total excisions. No recurrences or metastases were detected during the follow-up period of 6 months.
