A severe course of Cronkhite-Canada syndrome and the review of clinical features and therapy in 49 Chinese patients.
We describe a severe case of Cronkhite-Canada syndrome and review the clinical features and therapy in 49 Chinese patients. A 67-year-old man who underwent severe chronic diarrhea had typical clinical manifestations of hyperpigmentation, hair loss, and dystrophic changes in the fingernails. Although sufficient nutrition support and other therapies reported in the literature were provided, the patient died of systemic failure one year later. Cronkhite-Canada syndrome is characterized by generalized gastrointestinal polyps associated with hyperpigmentation, hair loss, and onycholysis. Anemia, positive stool occult blood, serum electrolyte disturbances, and low serum proteins are the main clinical features of patients with Cronkhite-Canada syndrome. Most patients were diagnosed by esophagogastroduodenoscopy and/or colonoscopy, and polyps were found in the entire alimentary tract, except the notable exception of the esophagus. The polyp-like samples of mucosa, hyperplasia, and adenoma were characterized by acute/chronic inflammation. Four cases were complicated with cancer. The treatment of Cronkhite-Canada syndrome includes symptomatic and support therapy, administration of corticosteroids, antibiotics and acid inhibitors, therapeutic endoscopy, and surgery. While the mortality rate was reported as 47.3% (9/19), some patients may live a long life with controlled symptoms.
