Abstract

Granulation polyps are found in the colorectum often in association with postoperative anastomotic sites or scars after endoscopic resection. Meanwhile, few cases of granulation polyps that occur in relation to colonic diverticula have been reported. Herein, we report three cases of diverticula-related granulation polyps in the colon. In all three cases, a reddish polyp that protruded from a diverticulum was found in the sigmoid colon. White exudate and tortuous capillaries were observed on the surface of the polyps. On magnifying endoscopic observation, the surface structure was unclear or had disappeared. We speculate that these endoscopic features are specific to granulation polyps in the colon. It is noteworthy that in one patient with laryngeal cancer, the polyp was false-positive for a tumor on positron emission tomography, showing significant tracer accumulation. Differentiation of granulation polyp from cancer metastasis to the colon is important in such patients. It is essential to be able to make a precise diagnosis of diverticula-related granulation polyp in the colon based on endoscopic features.
