Congenital Melanocytic Nevus and Fibroepithelioma of Pinkus: A Rare Type of Collision Tumor

Abstract

Congenital melanocytic nevus is a benign pigmented lesion of the skin usually present at birth. Here we report a case of a 61-year-old male who presented with a pigmented lesion on the trunk, which on biopsy showed features of both congenital melanocytic nevus and fibroepithelioma of Pinkus. We reviewed the literature for this combination and found only one case reported so far. Hence, it seems that it is very unusual to see fibroepithelioma of Pinkus in conjunction with a melanocytic lesion.
