Surgical Treatment of Macrodystrophia Lipomatosa Involving Superficial Peroneal Nerve in the Foot and Ankle

Abstract

Macrodystrophia lipomatosa is a congenital disease characterized by gradual proliferation in the mesenchymal cell, such as fibroadipose tissue. Pathologically, fatty tissue is deposited in the nerve sheath, periosteum, bone marrow, and subcutaneous tissue, contributing to the macrodactyly of the foot. To date, there has not been any report on macrodystrophia lipomatosa of the superficial peroneal nerve in the Korean orthopedic literature. Conservative approach, such as decompression or debulking surgery, is recommended due to neurogenic dysfunction. However, we report a 43-year-old male with macrodystrophia lipomatosa involving the superficial peroneal nerve of the right foot and ankle, who underwent a second toe ray amputation as well as soft tissue and nerve resection.
