Intra osseous schwannoma of inferior alveolar nerve with multilocular radiolucency crossing the midline: A case report

Abstract

Schwanomma is a soft tissue tumor derived from Schwann cells of the peripheral nerves system. Schwannoma of the oral and maxillofacial regions primarily appears in soft tissue with tongue being the common site. Schwannoma arising within the bone are rare and commonly involve the mandible compared to maxilla. In this article, we report a case of rare intra-osseous schwanomma crossing the midline, which presented as a multilocular lesion on radiograph, which is again very rarely seen. Chief complaint of the patient was swelling and pain. Panoramic Radiograph showed a solitary oval shaped radiolucency with corticated borders and scalloping. Biopsy report revealed connective tissue component comprising of hyalinized stroma and tumor cells with large number of siderophages and histiocytes suggesting intra osseous schwannoma. Surgical resection performed and histopathologically examined confirming intra osseous schwannoma of ancient type. The post-operative course of the patient was uneventful for 2 years.
