Benign plexiform schwannoma of the superficial peroneal nerve: A case study

Abstract

Plexiform schwannomas are rare benign tumors originating from Schwann cells on the basal lamina in both the peripheral nervous system and the central nervous system. Less common is their presence in the foot and ankle, but when they are found, they usually present on the plantar foot. Although these tumors do not typically metastasize, they can cause serious local complications affecting neural structures, vascular structures, and nearby osseous structures. This case study describes a rare case of plexiform schwannoma of the ankle originating from the superficial peroneal nerve in a 54-year-old woman. Radiographic analysis and persistent symptomatology led to surgical excision and pathologic confirmation of the lesion. Meticulous removal of the tumor alleviated the symptoms without causing any distal neural deficits, highlighting the importance of treatment with careful surgical resection.
