Neurilemmoma (Schwannoma) may be in all parts of the body, but it is rare in theregions of the jaw and oral cavity. In this report we presented a case of neurilemmoma located in the tongue with its electronmicroscopic and histochemical studies, and reviewed cases of neurilemmoma in the region of the tongue as reported in the Japanese literature. The patient, a 17-year-old female, appeared at our dental clinic with the chief complaint of tongue pain. She first noted the painless swelling of the tongue with no other symptoms in May 1986 But she noted the tongue pain after about one year and was introduced to our dental clinicin April, 1988. The familial and past history was unremarkable. On physical examination, there was an elastic soft and movable hemispherical mass the size of the tip of the thumb. The clinical diagnosis was a benign tumor of the tongue. The lesion was totally excised under general anesthesia in May 1988. The removed hemispherical mass measuring 30×20×20mm was encapsulated by thin film. The tumor was diagnosed histopathologically as a neurilemmoma of Antoni. A type partially with Antoni B type. In addition, an immunohistochemical study using the antibody of s-100 protein was carried out. There was no evidence of recurrence 10 months after the operation.
