Schwannoma is an endodermal tumor originating from schwann's cell of myelinated nerves. There are few cases of schwannoma in the oral region, especially in the jaw. We have experienced a case of central schwannoma of the mandible. The patient, a 53-year-old woman, was pointed out a radiolucent area in the right lower part of the jaw by a dentist, and she visited our hospital. Based on the clinical diagnosis of radicular cyst, the lesion was enucleated under local anesthesia November 4, 1986. Histopathologically, the section demonstrated a dense proliferation of slender cells with spindle-shaped nuclei in a whorl or palisading arrangement. It was diagnosed as schwannoma, Antoni type A. It is reported that schwannoma infrequently recurs and the patient has a favorable postoperative course without any recurrence for a year.
