Abstract
The case is a 62 years old male. No polyposis was found by upper gastrointestinal endoscopy or barium enema examination performed at the time of cholecystectomy in March 1994. Symptoms such as dysgeusia, diarrhea, loss of hair and atrophy of nails began to appear from May. Examination of the digestive tract performed in October revealed clustered polyposis in the stomach, duodenum, small intestine and large intestine. Pathologically, all the polyps were found to be of the juvenile type, so a diagnosis of Cronkhite-Canada syndrome (CCS) was made. Histologic patterns of rectal polyp after polypectomy showed well differentiated adenocarcinoma continuous with the juvenile type polyp. The above-mentioned symptoms improved with the clinical course. At present, 6 years after the development of the disease, no recurrence of polyposis in the stomach and large intestine has been found. Our results suggest that ectodermal changes and lesions of the digestive tract in CCS appear and disappear in a short time.
