Abstract

Inflammatory myoglandular polyp is an uncommon benign colorectal polyp. We treated nine cases of histologically verified inflammatory myoglandular polyp. The polyps were identified as a pedunculated protrusion located in the distal part of the large intestine. On colonoscopy, eight polyps had a smooth, spherical, and hyperemic surface, accompanied by a patchy mucous exudate. Magnification endoscopy revealed a rugged surface composed of smooth nodules. These colonoscopic findings corresponded to hyperplastic glands with occasional cystic dilation and inflamed stroma with proliferation of smooth-muscle fibers. Inflammatory myoglandular polyp appears to be a distinctive clinical entity, with a unique appearance on colonoscopy.
