Cronkhite-Canada syndrome: A rare case report and literature review

Abstract

Cronkhite-Canada Syndrome (CCS) is a rare, non-hereditary disease characterized by gastrointestinal polyposis associated with diarrhea and epidermal manifestations, such as hyperpigmentation, alopecia, and onychodystrophy. The pathogenesis of CCS is still not well understood but it probably involved autoimmune mechanism. Herein, we here report a case of steroid-responsive CCS in a male patient whose polyps presented with IgG-4 positive plasma cells.
