Complex reconstruction after wide excision of juvenile aponeurotic fibromatoses of upper one-third of leg

Juvenile musculoaponeurotic fibromatoses are benign tumors which arise from musculoaponeurotic stromal cells. They rarely occur in lower extremity and more rarely in children. They are locally invasive tumors with a high incidence of recurrence after surgery. Hence, wide local excision is the treatment of choice for such tumors. However, complex reconstruction is often required to cover the resulting soft tissue defect. This report presents a 12-year-old boy with a juvenile musculoaponeurotic fibromatosis in the anteromedial aspect of the upper third of a left leg. Following wide local excision, two local flaps, medial gastrocnemius and a distally based peroneal artery perforator flap, were used to reconstruct the soft tissue defect. Reconstruction has provided an acceptable functional and cosmetic result.
