Abstract
Dermatofibrosarcoma protuberans (DFSP) is an invasive soft tissue tumor with asymmetric pattern of growth and propensity for recurrences, thus warranting systematic treatment planning at onset. We conducted a retrospective analysis of 25 patients with DFSP that received either wide excision, modified wide excision (with horizontal processing), Mohs micrographic surgery (MMS), or combination surgery. Follow-up ranged from 15–133 months, with a median of 68 months. Fourteen patients were treated with wide excision, 4 with modified wide excision, 6 with MMS followed by modified wide excision, and 1 with MMS. No recurrences were reported. Patients with lesions arising from “cosmetically sensitive” areas (head and neck) most often underwent MMS or modified wide excision. Our study supports that all 4 surgical treatment methods were successful in achieving recurrence-free survival, but emphasis on presurgical planning and patient selection for each surgical approach is key to allow for the least complicated repair while maximizing tissue preservation.
