EARLY MUCINOUS ADENOCARCINOMA OF THE COLON : REPORT OF A CASE

Abstract

A 62-year-old man was pointed out positive fecal occult blood in screening test with no subjective symptoms in 1988 and in 1989. Barium enema and colonoscopy examined by a familial doctor revealed a pedunculated polyp of the sigmoid colon. The biopsy specimen revealed no malignancy pathohistologically. We performed the endoscopic polypectomy. The pedunculated polyp removed by endoscopic polypectomy showed the reddish head 30 × 15 × 15 mm in size that was present on a white stalk with mucinous tubercle mucin and it was confirmed pathohistologically as mucinous adenocarcinoma invading to submucosa. Most of reported cases of mucinous adenocarcinoma in the colon were advanced cancer, but our case was a early cancer. To the best our knowledge, early mucinous adenocarcinoma of the colon like this cases has rarely been reported and it was supposed to be a important case.
