 In order to clarify the difference between cap polyposis (CP) and mucosal prolapse syndrome (MPS), radiographic and endoscopic appearance was investigated in six cases of CP and 10 cases of MPS. Hypoproteinemia was noted in four cases of CP. Radiographically, multiple protrusions, predominantly located in the anterior wall of the rectum, were characteristic of MPS, while protrusions were located circumferentially in the rectum and the proximal part of the colon in CP. Under endoscopy, whitish nodular protrusions were found in seven cases and edematous mucosa in three cases of MPS. The rectal protrusions of CP were characterized by reddish nodular protrusions in four cases and by flat-topped protrusions with central depression in two cases. However, the configuration of the protrusions in the proximal part of the colon was similar in all cases of CP. Diminutive white specks were observed in the intervening mucosa of CP, while such specks were not found in MPS. Based on these findings, we concluded that CP should be distinguished from MPS.
