 This paper investigates the difference in the endoscopic findings of mucosal prolapse syndrome of the rectum (MPS) and cap polyposis (CAP). 18 patients of MPS were selected for follow-up observation, from among 35 patients (male: 17 cases 41.5±18.1 years old, female: 18 cases 55.3±16.3 years old) who were diagnosed as MPS by endoscopy and pathological examination and whose lesions were classifed as ulcer type (23 cases), flat type (3 cases) and protruded type (11 cases). The protruded type of MPS is similar to CAP, and the protruded type was divided roughly into the polypoid type and submucosal tumor type. Protruded lesions were distributed at the lower part of the rectum and reduction or disappearance was brought about by desisting from straining. CAP distribution was limited to the rectum and sigmoid colon, and the lesions were circular, different in size and with attached mucus. CAP was associated with low protainemia. The clinical course of MPS was different CAP from that of CAP.

 It is concluded that CAP should be distinguished from MPS because of the difference of endoscopic findings and the clinical course.
