Background: Providing soft-tissue coverage after wide excision of dermatofibrosarcoma protuberans (DFSP) is always challenging; according to the literature, a skin graft is often chosen as the first option. However, possible suboptimal functional and cosmetic results have been noted.
Aims and objectives: We present our 10-year experience using pedicled or free flaps for reconstruction after a wide excision of DFSP to provide adequate soft-tissue augmentation and enhanced esthetic results.
Materials and methods: This was a retrospective study comprising 14 DFSP patients who were treated between February 2003 and December 2013. All patients underwent a wide excision with a 3-cm safe margin with immediate reconstruction, and a negative deep margin confirmed with a frozen section. The reconstruction method included nine pedicled perforator flaps and five free perforator flaps. All patients received adjuvant radiotherapy after surgery.
Results: The peak incidence that occurred in this serieswas the highest in patients younger than 30 years. None of the 14 patients exhibited recurrence, and themean follow-up time was 30months. Half of the patients exhibited DFSP distributed over the trunk; the patients in the series were predominantly male. A total of 13 flaps were successful except for one pedicled flap that failed from venous congestion;we used it in a salvage procedure by using full-thickness skin graft for coverage.
Conclusion: A wide excision with a 3-cm margin of safety with immediate reconstruction is a reliable method for DFSP resection. Initiating adjuvant radiotherapy might reduce the chance of local recurrence. To minimize the complications of skin graft, pedicled, or free flaps provide superior
functional outcome, soft-tissue augmentation, and esthetic results. |
