| Description |
Cronkhite-Canada syndrome (CCS) is a rare noninherited condition characterized by gastrointestinal hamartomatous polyposis, alopecia, onychodystrophy, hyperpigmentation, and diarrhea. CCS is reported worldwide, with 75% of cases in Japan. The average age of onset is 60 years and the male to female ratio is 3:2. At present, the pathogenesis of CCS is unknown, but the factors that include immune abnormalities, infection, and allergies, may be relevant. There are no evidence-based therapies. Numerous treatments have been attempted in CCS patients, with varying degrees of success. These treatments include glucocorticoids, nutritional support, antibiotics, and polypectomy.
