[Cronkhite-Canada syndrome - a rare intestinal polypotic syndrome].

Cronkhite-Canada syndrome is a rare polypotic disease of the gastrointestinal tract. There are no specific diagnostic criteria for this syndrome. Suspicion may arise if both an endoscopic and a histopathologic finding together with the patient's symptom picture are indicative of the disease. Other polypotic conditions should be excluded. No established treatment is available for the syndrome. The principles of treatment have remained almost unchanged at least over the past decade. With a large proportion of the patients eventually developing a gastrointestinal malignancy, the prognosis of the disease is mostly poor.
