Postradiation Dermatofibrosarcoma Protuberans: Case Report and Literature Review.

ABSTRACT

Radiotherapy has long been known to induce soft tissue sarcomas. However, there are only six cases of post-radiation dermatofibrosarcoma protuberans (DFSP) reported in the literature, and no case in Asians has been reported so far. Herein, we report a case of DFSP, confirmed by immunohistochemistry, which developed on the old scar at the irradiated right chest wall of an Asian woman. We performed a radical surgical excision of the lesion and covered the defect with latissimus dorsi island myocutaneous flap followed the surgical treatment. 12 months postoperatively, the patient leads a good result without signs of recurrence.
