Wide Excision and Anterolateral Thigh Perforator Flap Reconstruction for Dermatofibrosarcoma Protuberans of the Face

Dermatofibrosarcoma protuberans is a rare cutaneous malignant tumor associated with a high cure rate but with a high incidence of local recurrence. Because of its tentacle-like subcutaneous infiltrating pattern that extends far beyond the clinically visible skin lesion, a wide resection margin is recommended. Hence, its localization to the head-and-neck regions, although rare, represents a real challenge for both the oncologic surgeon and the reconstructive surgeon, who aim to achieve a radical resection of the tumor with the best possible aesthetic outcome. A case of a 21-year-old Mediterranean man who presented with a 7-month history of a slowly growing subcutaneous lesion of the left preauricular region is reported. A diagnosis of dermatofibrosarcoma protuberans CD34+ was confirmed through surgical biopsy, and the patient subsequently underwent a wide en bloc local surgical resection, followed by anterolateral thigh perforator free flap reconstruction. Healing was uneventful. Initially, there was some facial nerve neurapraxia; however, this completely subsided within 3 months after the surgery. At the 13-month follow-up, the patient was completely well and free from the disease.
