Schwannoma of the lower lip mucosa: An unexpected finding

Abstract

Of all neurogenic tumors, about half are seen in the region of head and neck. Schwannomas are benign tumors of Schwann cells nerve sheath and are quite uncommon in the oral cavity, rarely occurring in the lip area. A MEDLINE search of the literature in English from 1969 to 2013 revealed only 20 documented cases of schwannomas of the lip. In the current study, authors reported a case of an intraoral schwannoma located in the lower lip. The diagnosis was established based on clinical and histopathological findings of the schwanoma which was treated by complete surgical excision. Although rare, schwannoma should be considered in the differential diagnosis of any nodule or mass in the oral mucosa.
