 The concepts, clinical features, diagnoses and treatment of rectal ulcers other than IBD, infectious diseases, mucosal prolapsed syndrome and cap polyposis are described. The disorders dealt with in this chapter include radiation proctitis, ischemic proctitis, acute hemorrhagic rectal ulcer, rectal Dieulafoy-type ulcer, stercoral ulcer and NSAID-suppository induced proctitis. Radiation proctitis and NSAID-suppository induced proctitis can be diagnosed based on the anamneses. Rectal Dieulafoy type ulcer can be easily recognized from the characteristic endoscopic images. However, the other disorders are often confused with each other because of insufficient recognition, although clinical features are considerably different among the disorders. On the other hand, the concept of rectal ulcers should be reviewed and the implication of cytomegalovirus infection should be elucidated.
