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.

Rhinosporidiosis is a chronic, granulomatous, mucocutaneous infection caused by Rhinosporidium seeberi . The infection is non-contagious and sporadic in humans. The site most commonly affected is the mucous membrane of the nose and nasopharynx, followed by the oropharynx, trachea, bronchi, ear, eye, and genitourinary tract. It can also spread to other areas through blood and lymph. Here, we report a case of rhinosporidiosis affecting the palate in a 60-year-old female patient.

Rhinosporidiosis is a chronic granulomatous infectious disease caused by Rhinosporidium seeberi, which is endemic to South India, Sri Lanka, and parts of Africa. It is primarily an infection of the nose. Although involvement of other parts of body has occasionally been reported, it rarely presents as a disseminated disease. We describe a case of nasal rhinosporidiosis in Korea and discuss its clinical manifestations and management.
