title: Endoscopic removal of giant intranasal schwannoma.
abstract: Schwannoma is a benign neoplasm originating from schwann cells of the peripheral nerve sheath. Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are very rare in the literature. We present a case of nasal schwannoma originating from the right nasal cavity. A 59-year-old man presented with complaints of progressive right nasal obstruction and headache. Endoscopic examinations revealed a mass that filled the right middle meatus. At first glance, it was not like polyp tissue. Endoscopic sinus surgery was performed under general anesthesia, and the mass was completely removed.
