Abstract
Neurilemmoma (Schwannoma) is a benign nerve sheath tumor that’s composed entirely of welldifferentiated Schwann cells. Intraosseous neurilemmomas are rare and they represent less than 1% of all benign primary bone tumors. We report here on an additional case of intraosseous neurilemmoma that was located in the mandible of a 77-year-old woman. CT revealed an expansile, well-defined lesion on the right side of the mandibular body with thinning of the cortex. The lesion was surgically removed and it was found to be a 2×1.7 cm-sized, bright yellowish, hard mass with hemorrhage and cyst formation. Histologically, the mass was a moderately cellular neoplasm and it showed distinct nuclear palisading, numerous Verocay bodies and tumor cells that were positively immunohistostained for S-100 protein. Two months after the operation, the patient has remained in a good condition with no signs or symptoms of tumor recurrence.
