It has been accepted that the rectum is almost always involved in ulcerative colitis (UC). However, there has been a few reports that rectal sparing may be seen in a small percentage of patients with typical UC. We present two cases of rectal sparing UC associated with primary sclerosing cholangitis diagnosed simultaneously in nonsmokers. We hope the cases could be helpful to establish more definitely the existence of rectal sparing UC as an independent identity stemmed from Crohn's disease.
