초록
We report herein three cases of inflammatory myoglandular polyp (IMGP) presenting as hematochezia. The polyps had pedunculated, red, and smooth features,and were 12, 12, and 15 mm in diameter and located in the sigmoid colon, transverse colon, and rectum, respectively. Endoscopic polypectomies were performed. Histologic examination of the recovered specimens revealed inflammatory granulation in the lamina propria mucosa, proliferation of smooth muscle,and hyperplastic glands with cystic dilatation. The three colon polyps were finally diagnosed both clinically and histologically as IMGP. Endoscopists should bear in mind that a polyp featuring endoscopic findings of pedunculation or semipedunculation; a red,smooth, spherical, and hyperemic surface; and patchy mucosa exudation and erosion is likely to be an IMGP.
