Peripheral nerve sheath tumor of the medial plantar nerve without tarsal tunnel syndrome: a case report.

Abstract

Peripheral nerve sheath tumors are relatively uncommon soft tissue tumors, and the incidence of peripheral nerve sheath tumors localized to the plantar surface of the foot, without symptoms of tarsal tunnel syndrome, is even more rare. In this report, we present the rare case of a patient with a peripheral nerve sheath tumor originating from the medial plantar nerve in the plantar vault. The tumor was enucleated and fully excised under microscopic inspection using fine-tipped instrumentation, without en bloc resection of the associated nerve trunk. Surgeons should consider peripheral nerve sheath tumor as a cause of plantar foot pain, despite the rarity of this disorder. 4.
