Abstract

Skin neoplasms can result in large skin defects after surgical removal. Skin grafting has been used commonly to repair large defects, but it is associated with esthetic and functional problems. Herein, we report three cases with application of the keystone island flap in large skin defects of the trunk and extremities. A 53-year old male with recurred dermatofibrosarcoma protuberans on his thigh was repaired by the keystone island flap after Mohs micrographic surgery, and a 52-year old male with malignant melanoma on his back was successfully reconstructed by the keystone island flap after wide excision. Lastly, a 59-year old male diagnosed with dermatofibrosarcoma protuberans on the inguinal area was closed by the keystone island flap with commendable cosmetic outcome. Due to the ease of performance, excellent cosmetic and functional results, we recommend the keystone island flap for the reconstruction of large skin defects on the trunk and extremities.
