Choanal polyp originating from the inferior turbinate presenting as nasal polyposis.

Although choanal polyps frequently arise from the maxillary sinus, a choanal polyp originating from the inferior turbinate is a rare entity. A 14-year-old girl who had a history of bilateral nasal obstruction with snoring, mouth breathing and nasal discharge for 10 years was presented. On endoscopic examination, a polypoid mass completely obliterated the right nasal cavity. The left choana was also totally occluded by the polypoid mass. Endoscopic polypectomy was performed and it was observed that the polyp originated from the right inferior turbinate. Choanal polyps arising from the inferior turbinate should be kept in mind in the differential diagnosis of unilateral nasal polypoid masses.
