Schwannoma, alternatively designated as neurinoma or neurilemmoma, is a benign tumor of the neural sheath origin. It typically appears as a well-circumscribed solitary mass. Although the most frequently affected site is the central nervous system of the head and neck region, this tumor is uncommon in the oral cavity. Here we report six cases of Schwannoma of the oral cavity. Patients were referred to our hospital with intraoral swelling or nodules from 1989 to 1999. There were five females and one male, and the age range was 15 to 59 years with the mean of 27.7. Masses were found in the tongue in four cases and in the lip in two cases. All the tumors were surgically enucleated under local anesthesia. Histopathologic examination revealed that four tumors displayed Antoni A pattern and one of the other remaining cases displayed Antoni B pattern. The remaining one was found as a mixed type of Antoni A and B. No signs of recurrence have been observed during the postoperative follow-up.
