THE SO-CALLED antrochoanal polyp, rising from the antral mucosa, has appeared to be clinically different in character from the usual nasal polyp although grossly similar in appearance.
One of us (H. L. W.)1 stated that the antrochoanal polyp seemed different to him for the following reasons: 1. Many of the antrochoanal polyps appear to arise from a small area of mucosa on the posterior superior wall of the affected antrum. 2. Often the choanal polyp is the only example of polypoid change occurring on either side of the nose, and, not infrequently, when the affected antrum is opened the stalk of the polyp is the only evidence of such change in the mucosa. 3. If the polyp is grasped in the nose or in the nasopharynx and avulsed, it frequently recurs, still maintaining its solitary character. 4.
