 The anorectal lesion accompanying inflammatory bowel disease(IBD)was studied in our institution. Out of 240 patients with Crohn's disease, whose anorectal region was routinely examined,201(83.8 %)presented with some sort of anorectal lesion. A perianal fistula/abscess was the most common with a frequency of 61.7%. Other main lesions included a skin tag in 74 patients(31.3%)and a fissure/ulcer in 58(24.2%). The anorectal lesions of Crohn's disease were characterized by the mixed existence of these lesions in many locations. Eighty one patients(33.8%)initially presented with these anorectal lesions before abdominal symptoms were experienced and 44(18.3 %)had been diagnosed with Crohn's disease because of an anorectal lesion.

 For patients with ulcerative colitis, anorectal lesions presented with a frequency of 17.0 %, and were similar to common lesions in appearance. It is considered that knowledge of the varied significance of the anorectal lesion is very helpful for the differential diagnosis of IBD, especially in cases of Crohn's disease.
