Combined sliding flap using a single perforator enables simple closure of the donor site: a case report.

We report the case of a 39-year-old man with a dermatofibrosarcoma protuberans (DFSP) on the right shoulder. A wide surgical excision of the tumour was performed, creating a 12-cm-wide defect. An anterolateral thigh flap created from two semicircular skin paddles was harvested and the two skin paddles were slid towards each other to cover the circular defect. The sliding technique is a useful design that preserves the suprafascial plexus and enables a single perforator to supply two split-skin paddles. Using this design, the donor site can be closed primarily without requiring a skin graft. This technique can be applied to other free flaps to reconstruct wide defects after the resection of cancers.
