Abstract
Schwannoma is rare in the oral cavity, although this tumor can occur in virtually in any part of the human body. We, herein, report two cases of Schwannoma which originated in the tongue. The first case was a 33-year-old male who visited our hospital with the chief complaint of a mass and pain on the right side of his tongue. A firm submucosal tumor with a smooth surface was found on the right side of his tongue. The tumor was removed with a YAG LASER under general anesthesia in February 1993. The tumor measured 20×15×15mm in size. A histological examination showed the tumor cells to have a palisading cellular arrangement of Antoni type A cells which were positive for S-100 protein. This tumor was thus diagnosed to be a Schwannoma in the tongue. The second case was a 47-year-old female who presented with a mass on the left side of her tongue. The tumor was removed under local anesthesia in June 1996. The tumor measured 22×17×13mm in size. It was also histologically diagnosed to be a Schwannoma in the tongue. After surgery no evidence of tumor recurrence has been seen for 5 years in the first case and for 20 months in the second case.
