Cronkhite-Canada syndrome presenting as eosinophilic gastroenteritis.

Cronkhite-Canada syndrome (CCS), first described in 1955, is a rare clinical syndrome of unknown etiology. CCS is diagnosed clinically, and the presenting symptoms include alopecia, cutaneous hyperpigmentation, gastrointestinal polyposis, and onychodystrophy, often accompanied by diarrhea, weight loss, and abdominal pain. We describe a unique case of CCS that presented with eosinophilic infiltrate on gastric and duodenal biopsies and review the literature pertaining to this rare syndrome.
