Antrochoanal polyp mimicking juvenile nasoangiofibroma.

ABSTRACT

Antrochoanal polyp is a benign lesion, usually arising from the maxillary sinus extending posteriorly into the nasopharynx. Typically it presents as a unilateral nasal obstruction with mucopus rhinorrhea, sleep disturbance, postnasal drip, and mouth breathers. Epistaxis is an extremely rare complaint. Unilateral nasal mass presenting in a teenage boy will increase the suspicion of juvenile nasoangiofibroma. We report a teenage with extensive unilateral nasal mass with such presentation, which later turned out to be antrochoanal polyp.
