A schwannoma is one of the most common neoplasms in the central and peripheral nervous systems, but schwannomas of the sciatic nerve are rare. Treatment is a surgical excision and the overall prognosis is good. But functional loss occurs when a neurectomy is performed with inevitable cause. We report one case of a successful sural nerve graft after resection of a schwannoma in a sciatic nerve and we present a brief review of the literature.
