A 26-year-old man presented with a 1-month history of nasal obstruction and left-sided epistaxis. The patient had no prior history of nasal trauma or sinusitis. Nasal saline, steroid sprays, and oral antihistamines did not relieve his obstructive symptoms. On endoscopic examination, the patient was found to have a fibrous-appearing mass filling the left nasal vault.
