The true choanal polyp-a case report

Whether one could distinguish if a large polyp occupying the nasal pharynx derives from the mucosa of the posterior superior wall of the antrum, ethmoids, or the choanae is a matter not clearly understood. Existing literature is somehow confusing on this subject. One definite fact is that these polyps, whatever the site of their origin, are rare. From the histologic point of view, the general opinion among pathologists is that choanal polyps do not differ histologically from the simple mucous polyps of the nose. The case we are reporting concerns a 65-year-old caucasian male, who for many years had a sensation of fullness behind the nose. Examination revealed a polypoid growth protruding below the margin of the soft palate. Surprisingly roenthenograms were not contributory. This polyp was removed by threading a long soft wire over a regular nasal snare. The free loop of the wire was passed through the anterior nose down to the pharynx where the polyp was threaded into this loop, and by pulling the free end of the wires, the polyp was totally removed without any bleeding whatever. A pathology report is attached as well as a picture of the polyp.
