A82-year-old man who had received resection of sigmoid colon cancer four years agowas referred to our hospital for post-operative follow-up colonoscopy. Colonoscopyrevealed a slightly raised white-yellowish soft plaque at the sigmoid colon measuring aboutlcm in diameter. The lesion was negative for non lifting sign, and we perfermedendoscopic mucosal resection of the lesion. The histological finding of the specimen washistiocytic granuloma in the mucosa and the cytoplasm of these histiocytes showed roundlaminated inclusions(Michaelis-Gutmann bodies)that were positive for iron and calcium, thus confirming it to be a case of malacoplakia.
