Abstract
A case of extremely rare neurinoma of the lingual nerve is reported. The patient was a 54-year-old man whose chief complaint was a painless mass in the left mandibular region. The preoperative diagnosis was a left mandibular gland tumor and the patient was thus operated on. The operative findings revealed neurinoma of the lingual nerve, and both the left submandibular gland and the tumor were thus removed completely. The findings of a histopathological examination indicated Antoni A and B neurinoma.
