Plaque-Like Dermatofibroma: Case Report of a Rare Entity

Sara Moradi et al. Dermatopathology (Basel). .

Abstract

A case of a well-demarcated plaque measuring 11 cm without satellites of several years' duration is presented. It showed typical histologic findings of dermatofibroma, prompting a diagnosis of plaque-like dermatofibroma. The relationship to multiple clustered dermatofibromas and plaque-like myofibroblastic tumor is discussed.

Keywords: giant dermatofibroma; histopathology; multiple clustered dermatofibromas; plaque-like dermatofibroma; plaque-like myofibroblastic tumor.
