BACKGROUND: Neurofibromatosis type 1 (NF-1) is a locally invasive tumor that can grow extensively with diffuse infiltration into surrounding tissue. Resecting a large neurofibroma can result in an extensive defect that is difficult to reconstruct and can cause both aesthetic and functional deformities. METHODS: From 2000 to 2010, 5 patients with NF-1 underwent radical resection and immediate reconstruction with 6 free flaps at our institution. All patients presented with recurrent tumor, and involved head and neck region in 4 and foot in 1 patient. Ages ranged from 18 to 75 years. The follow-up ranged from 1 to 94 months. RESULTS: Defect sizes ranged from 84 to 252 cm. A single free flap was used in 4 cases and 2 free flaps were used in 1 case. All the flaps survived. Complications included loss of skin graft, necrosis of the distal tip of a flap, and wound dehiscence. All complications were successfully managed with minor surgical procedures. CONCLUSION: Immediate reconstruction using a free flap after resecting a large neurofibroma is a safe and reliable method that facilitates radical resection of the tumors that are difficult to resect and that may result in an extensive defect.
