There has been much debate over the past 50 years concerning the associatio
n between colorectal carcinoma and inflammatory bowel disease. Until recent
ly, it was widely accepted there was a higher risk in those with widespread
ulcerative colitis. However, evidence now suggests an almost equal inciden
ce in those with Crohn's disease of similar extent and duration.(1) We pres
ent a case that underlines the important clinical and pathological features
of Crohn's disease associated colorectal carcinoma (CDAC). We present a li
terature review and debate the role of regular colonic surveillance in pati
ents with Crohn's disease affecting the colon.
