Ancient schwannoma of the nasal septum associated with sphenoid sinus mucocele.
Schwannoma is a benign tumor arising from the sheath of myelinated nerve fibers and may occur in any part of the body. Ancient schwannoma, a variant of schwannomas, in the head and neck region is uncommon, and its occurrence in the nasal cavity and paranasal sinuses is extremely rare with only one case reported to date. Herein, we describe a rare case of sinonasal ancient schwannoma. The tumor arose from the nasal septum and extended to the sphenoid sinus. It was successfully treated by endoscopic sinus surgery, and the patient showed no evidence of recurrence 24 months postoperatively.
