 Anorectal lesions of patients with inflammatory bowel disease were presented in this paper. A variety of anorectal lesions occur in Crohn's disease patients with relatively high incidence. These lesions were considered by focusing on the basis of primary, secondary and incidental lesions. Primary lesions derive from the same inflammatory pathological processes that occur in the intestine. Secondary lesions arise from primary lesions and incidental lesions are those not related to Crohn's disease. This classification is useful for assessing anorectal lesions in relation to their clinical course and management.

 It should be noticed that the number of patients with anorectal carcinoma complicating Crohn's disease are increasing in Japan.

 Whereas the incidence of anorectal lesions of ulcerative colitis is low and most of them are incidental. The presence of anorectal lesion may change the operative procedure, if the patient needs surgical intervention.

 To maintain good quality of life for patients with inflammatory bowel disease, it is important to make precise assessment of the anorectal lesions and to select optimal management.
