Cronkhite–Canada syndrome is a rare syndrome characterised by multiple polyps of the digestive tract. It is sporadic (i.e. it does not seem to be a hereditary disease),[1] and it is currently considered acquired[2] and idiopathic (i.e. cause remains unknown).
About two-thirds of patients are of Japanese descent and the male to female ratio is 2:1.
It was characterized in 1955.[3][4]

Presentation[edit]
Polyps are most frequent in the stomach and large intestine, are also found in the small intestine, and are least frequent in the esophagus. A biopsy will reveal them to be hamartomas; the possibility that they progress to cancer is generally considered to be low,[5] although it has been reported multiple times in the past. Chronic diarrhea and protein-losing enteropathy are often observed. Possible collateral features include variable anomalies of ectodermal tissues, such as alopecia, atrophy of the nails, or skin pigmentation
Cause[edit]
The cause of the disease is unknown. It was originally thought that the epidermal changes were secondary to profound malnutrition as a result of protein-losing enteropathy. Recent findings have called this hypothesis into question; specifically, the hair and nail changes may not improve with improved nutrition.
Other conditions consisting of multiple hamartomatous polyps of the digestive tract include Peutz-Jeghers syndrome, juvenile polyposis, and Cowden disease. Related polyposis conditions are familial adenomatous polyposis, attenuated familial adenomatous polyposis, Birt–Hogg–Dubé syndrome and MUTYH.
Treatment[edit]
Treatments proposed include cromolyn sodium and prednisone.[6]
