摘　　要：BACKGROUND Cronkhite-Canada syndrome(CCS)is a rare nonhereditary disease characterized by chronic diarrhoea,diffuse gastrointestinal polyposis and ectodermal manifestations.The lethality of CCS can be up to 50%if it is untreated or if treatment is delayed or inadequate.More than 35%of the patients do not achieve long-term clinical remission after corticosteroid administration,with relapse occurring during or after the cessation of glucocorticoid use.The optimal strategy of maintenance therapy of this disease is controversial.CASE SUMMARY A 47-year-old man presented to the hospital with a 3-mo history of frequent watery diarrhoea,accompanied by macular skin pigmentation that included the palms and soles,and onychodystrophy of the fingernails and toenails.Gastroscopy and colonoscopy revealed numerous polyps in the stomach and colon.After other possibilities were ruled out by a series of examinations,CCS was diagnosed and treated with prednisone.The patient took prednisone for more than 1 year before achieving complete resolution of his symptoms and endoscopic findings.The patient was then given prednisone 5 mg/d for 6 mo of maintenance therapy.With clinical improvement and polyp regression,prednisone was discontinued.Eight mo after the discontinuation of prednisone,the diarrhoea and gastrointestinal polyps relapsed.Therefore,the patient was given the same dose of prednisone,and complete remission was achieved again.CONCLUSION It is necessary to extend the duration of prednisone maintenance therapy for CCS.Prednisone is still effective when readministered after relapse.Surveillance endoscopy at intervals of 1 year or less is recommended to assess mucosal disease activity.
