Abstract

Schwannomas are benign neurogenic tumors arising from the peripheral nerve sheath and rare in the nasal cavity and paranasal sinus. About 4% of schwannomas in the head and neck area arise in the sinonasal cavity. As unilateral nasal masses in the nasal cavity and paranasal sinus, schwannomas are likely to be mistaken for more common lesions such as nasal polyps or mucoceles. We recently experienced a case of schwannoma on the ethmoid sinus in a 33-year-old male which was surgically removed. Herein, we report this unusual case of schwannoma on the ethmoid sinus with a brief review of literature.

Key Words: Schwannoma, Ethmoid sinus
