Plexiform Hypoglossal Schwannoma of the Tongue and the Submandibular Region

Abstract

Hypoglossal schwannomas usually develop in the intracranial portion of the brain. Incidence of hypoglossal schwannomas of the submandibular region is extremely rare. A 27-year-old patient presented to us with hypoglossal schwannoma of the tongue and the submandibular region. The tumor was excised intraorally combined with submandibular approach. Histopathologic examination revealed a plexiform schwannoma (a rare variant).
