A Case of Desmoplastic Spitz Nevus

Abstract

Desmoplastic Spitz nevus is a rare histological variant of Spitz nevus characterized by diffuse fibrosis without junctional activity, nesting, or pigmentation. Nevus cells are predomintantly spindle- shaped and compressed by a desmoplastic stroma. It presents typically as a firm, dome-shaped, flesh-colored papule or nodule, measuring up to 1cm in the greatest diameter, is most often located on extremities. We report a case of desmoplastic Spitz nevus occurring on the left side of the buttock in a 33-year-old women.
