Giant plaque-like dermatofibromas presenting over an atypical site

Abstract

Dermatofibroma, a benign fibrohistiocytic tumor, rarely presents as atypical lesions over sites other than its usual distribution which often poses a challenge in making a clinical diagnosis. Giant dermatofibroma is one such variant, presenting with pedunculated lesions larger than 5 cm in size. A subtype of giant dermatofibroma, plaque-like dermatofibroma, manifests clinically with indurated plaques, with eight such documented cases in the past.We are reporting one such presentation over a site that has not been documented in the existing literature to date.
