Abstract


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.


Keywords: Dermatofibrosarcoma Protuberans; Melanocytes; Pigmentation; Cell Differentiation; Case Report; India.
