The etiology of and optimal treatments for Cronkhite-Canada syndrome (CCS) are still undetermined. Fewer than 5% of CCS patients experience complete remission and 15% of CCS patients develop malignancies. Here, we present a case of CCS involving autoimmune disorders, in which rapid diagnosis, rapid commencement of therapy, and complete remission were achieved after 4 months of prednisolone therapy and polypectomy, although biopsy specimens from all residual colonic polyps revealed adenocarcinoma in one polyp 4 months after prednisolone therapy. It is important to identify gastrointestinal or colonic polyps harboring malignant changes and to examine the involvement of autoimmune mechanisms for better outcomes in CCS patients.
