Recurrent Dermatofibrosarcoma Protuberans - An Institutional Case Series over a Span of 7 Years

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, superficial sarcoma of fibroblastic origin, tends to recur locally. This study demonstrates the incidence, distribution and recurrence rate of DFSP. Methods: Over a span of 7 years, from January 2012 to December 2018, 11 cases of Dermatofibrosarcoma protuberans were reportedin Tertiary hospital, Chennai. Out of which 8 cases were recurrent tumors and 3 cases were primary tumors. Results: 8 out of11 patients presented with RecurrentDFSP. One patient had history of five times recurrence over a duration of 20years. One patient presented with the lesion since childhood. Among them 5 cases were male and 3 cases were female. 7 patients underwent wide local excision and 1 patient underwent excision biopsy. Post excision reconstruction included direct closure in 4 cases, split skin graft in 1 case and local or free flap in 2cases. Of the 8 patients, one received post operativeradiotherapy. Conclusion: Wide local excision with adequate circumferential and deep resected margins can effectively control the recurrence rate.
