Oncocytic Schneiderian papilloma (OSP) is a rare neoplasm of the nose and paranasal sinuses, and is often mistaken histologically for papillary adenocarcinoma or even rhinosporidiosis. Recently, we experienced a case of oncocytic Schneiderian papilloma of the left maxillary sinus developed in 53-year-old female patient. She complained of unilateral nasal obstruction, bloody rhinorrhea and frontal headache. The tumor mass was resected surgically through intranasal endoscopic and Caldwell-Luc's approach. We report its clinical manifestations and histologic characteristics.
