Rare Schwannoma Nerve Tumor in a Lesser Toe: A Case Report

J Am Podiatr Med Assoc. 2019 Jul;109(4):322-326. doi: 10.7547/18-054.

Abstract

A schwannoma is a solitary benign tumor composed of Schwann cells occurring anywhere in the peripheral nervous system. The diagnosis of a schwannoma is often difficult to make by clinical presentation and advanced imaging modalities. We present a case report of a 61-year-old Hispanic woman with a left-foot, third-digit, soft-tissue mass. The diagnosis of a schwannoma of the proper digital nerve was made postsurgically by means of histopathologic and immunohistochemistry parameters. This is a rare location for a schwannoma, and neurogenic tumor should be included in the differential diagnosis of soft-tissue mass, as there have been prior case reports.
