Cronkhite–Canada syndrome

Cronkhite–Canada syndrome is a type of non-hereditary hamartomatous polyposis syndrome characterised by rash, alopecia, and watery diarrhea.

There is a recognised male predilection. Patients typically are middle age, in their 60th 1.

Patients typically present with watery diarrhea and protein losing enteropathy and associated nail atrophy, brownish skin pigmentation, and alopecia 3.

Characterised by numerous hamartomatous polyps in the digestive tract, with predominant involvement of the stomach, large intestine and, to a lesser extent, small bowel. The exact aetiology is unknown and there is no recognised familial occurrence. Unlike other polyposis syndromes, it is not associated with a malignancy.

Polyps are similar to those of juvenile polyposis except that the mucosa among CCS polyps is oedematous and inflammation of the lamina propria usually present; in contrast,histologically the mucosa among juvenile polyps is normal 4.

On barium studies, this syndrome is characterised by polyposis involving the entire gastrointestinal tract. Gastric and colonic polyposis are both present in 100% of patients with this diagnosis. Small bowel involvement is seen in 50% of patients.

Initially described by L. W Cronkhite and W. J Canada in 1955 2.
