Intraosseous schwannoma of mandible: A case report
Keywords:
Mandible, nerve sheath tumors, neurilemmoma, neurinoma, schwannomaAbstract
Schwannomais a benign tumor derived from Schwann cell which is the myelinated nerve sheath. This tumor usually occurs in the head and neck region but intraosseous schwannoma in this region is extremely rare, i.e. less than 1% of the benign tumors of jaws. This article reports a case of unusual intraosseous schwannoma in the mandible. A 22-year-old male patient revealed facial swelling at the right side of the chin with occasional sharp shooting pain and numbness on pressing. The radiographic examination showed a well-defined round shaped unilocular heterogeneous radiolucency with sclerotic border and buccal bone expansion at the right side of the mandible. Histological finding demonstrated spindle-shaped cells arranged in Antoni A and B patterns. The tumor was totally enucleated under general anesthesia. The patient was followed up for 6 months after surgery and showed no recurrence.
