Central schwannoma of mandible

چکیده
Intraoral schwannomas are uncommon and intraosseous ones are even rarer. The intrabony lesions account for less than 1% of the central neoplasms.According to the literature, there have been reports of 44 cases of intrabony neurilemmomas that occurred in either of the jaws. In theis case report. we report a case of central schwannoma of the mandible in a 23-year-old female, who presented with a swelling involving the right body of the mandible. Radiographs revealed a well defined, unilocular radiolucency with bicortical expansion. Histopathology and immunohistochemistry confirmed the diagnosis of schwannoma arising from right inferior alveolar nerve. The lesion was treated by segmental resection and reconstructed with autogenous iliac bone graft.
