Recurrent dermatofibrosarcoma protuberans with pigmentation and myoid differentiation

Abstract EN

Dermatofibrosarcomas protuberans (DFSP) are rare low-grade tumours with various subtypes and usually occur among middle-aged adults.

However, myoid differentiation is very rare.

We report a 44-year-old woman who presented to the Lok Nayak Jai Prakash Hospital, New Delhi, India, in 2017 with a recurrent pigmented DFSP presenting as an arm swelling.

Upon histological and immunohistochemical analysis, myoid differentiation was confirmed.

A literature review of the clinical and histopathological features of this rare entity is presented
