Distal flap necrosis induced by excessive tissue tension. a) Giant congenital pigmented nevus on the right lower leg of a two-year old boy. b) Tissue expanders inserted on the lateral and medial sides of the upper thigh, filled to capacity. c) Lateral leg two days after resurfacing with rotation-advancement flap from expanded lateral thigh tissue. d) Medial leg two days after resurfacing with direct-advancement flap from expanded medial thigh tissue demonstrating distal flap necrosis. e) Necrotic tissue of distal flap debrided to promote healing by secondary intention. f) Medial leg two months after flap advancement, with healing of distal aspect of flap by secondary intention.
