[Ossification of nasal septal polyps: a case report].

This paper reported a case of a large septal polyp with central calcification. Nasal endoscopy revealed an irregular lobular mass, yellow and smooth, extending from posterior septum to nasopharynx. CT scan revealed a large nasal and nasopharyngeal mass, closely related to the septum, with ossification in the center. This mass was excised by endoscopic surgery and proved to be typical ossification of nasal polyps.
