A Case of Neurilemmoma Originating in the Hypoglossal Nerve Restricted to the Submandibular Region

Abstract

Neurilemmoma of the hypoglossal nerve is rare. We report a case of neurilemmoma that originated in the hypoglossal nerve.

A 59-year-old female was admitted to our hospital because of a submandibular swelling, and the clinical diagnosis was salivary gland tumor of the submandibular region. The tumor was removed together with the submandibular gland. Paralysis of the tongue was observed postoperatively. Histopathological analysis of the tumor revealed a neurilemmoma.

Although this case was rare, neurilemmoma should be considered in the differential diagnosis of a submandibular mass.
