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.
口腔内神经鞘瘤并不常见，骨内神经鞘瘤则更为罕见。骨内病变占中枢性肿瘤的比例不到1%。根据文献报道，已有44例发生于颌骨的骨内神经鞘瘤病例。在本病例报告中，我们报道了一例23岁女性下颌骨中枢性神经鞘瘤，患者表现为右下颌骨体部肿胀。X线片显示边界清晰的单房性透射区，伴有双层皮质膨胀。组织病理学和免疫组织化学检查确诊为源自右下牙槽神经的神经鞘瘤。该病变通过节段性切除治疗，并采用自体髂骨移植进行重建。
