Wounds after recision in recurrence of dermatofibrosarcoma protuberan in the left shoulder and chest repaired with anteromedial thigh perforator flap instead of anterolateral thigh perforator flap: a case report / 中华烧伤杂志

ABSTRACT

On October 23, 2017, a 52-year-old male patient with 3 recurrences of dermatofibrosarcoma protuberans in the left shoulder and chest was admitted to the Department of Burns and Plastic Surgery of Dali Bai Autonomous Prefecture People′s Hospital. Dermatofibrosarcoma protuberans on the skin were completely resected, leaving wound defect of 10 cm×10 cm. The wound was planned to be repaired by the transplantation of right anterolateral thigh perforator free flap. However, the anterolateral thigh perforator branch was absent during flap removal, and only one small perforating branch was found. Moreover, it was difficult to separate. Therefore, this flap cutting was given up. The anteromedial thigh perforator was explored through the same incision, and a thicker perforator was found, which was supplied by an independent iatrogenic artery. The length and diameter of the vascular pedicle matched with the blood vessels in the receiving site. An anteromedial thigh perforator flap (10 cm×10 cm) was cut to repair the defect. The postoperative 9-month follow-up revealed that the color, texture, and thickness of the flap were good, the two-point discrimination distance was 30 mm, and the linear scar remained at the donor site of right thigh.
