Cronkhite-Canada syndrome associated with advanced rectal cancer treated by a subtotal colectomy: report of a case.
A 41-year-old man with Cronkhite-Canada syndrome presented with multiple juvenile polyps with hyperplastic and adenomatous changes throughout his stomach and entire colorectum. Dysgeusia was recognized and the degree of hypoproteinemia was remarkable. A barium enema study and colonofiberscopy also revealed an advanced cancer in the rectum. Chronic hepatitis B and membranous glomerulonephritis were also present. It was difficult to design a conservative protocol using steroids for the treatment of protein-loosing enteropathy because the patient was a hepatitis B virus carrier. As a result, a subtotal colectomy while preserving the cecum with cecorectal anastomosis was performed. Pathologically, the ulcerated rectal tumor was a moderately differentiated adenocarcinoma with invasion into the muscularis propria. Most polyps showed cystically dilated glands without dysplasia or edematous stroma with inflammatory cell infiltration. A few polyps were juvenile-type polyps with adenoma components. Although no remarkable improvement was observed in the hypoproteinemia postoperatively, an alpha1-antitrypsin clearance test showed a significant decrease in protein loss from the gastrointestinal tract, which was only about one third of the loss seen preoperatively. These findings lead us to conclude that when improvement using conservative treatment can be neither obtained nor is expected, then the use of surgery should be considered when treating patients with Cronkhite-Canada syndrome.
