Case Report: A Rare Case of Dermatofibrosarcoma Protuberans
Abstract: Dermatofibrosarcoma protuberans (DFSP) DFSP is a low grade cutaneous malignancy first described in 1890 by Taylor. Darierwas credited with establishing DFSP as a clinicopathologic entity in 1924 and HOFFMAN established the term in 1925.Clinical diagnosis requires a high index of suspicion because the lesion often has a fairly innocuous gross appearance. After biopsy or excision, expert pathological assessment with focused immunohistochemistry testing is essential to differentiate DFSP with other superficial …
