Keystone-design perforator island flaps for the management of complicated epidermoid cysts on the back

Abstract Complicated epidermoid cysts (ECs) occur commonly on the back, but few reports have described their management. We present our experience in managing patients with ECs on the back using a keystone-design perforator island flap (KDPIF) reconstruction, thereby focusing on reduction and redist...
