Colonic malignancy is a clinically significant complication of Crohn disease in patients with pancolitis beginning in childhood. Although the risk of malignancy in Crohn disease is not as high as that in UC, the risk of adenocarcinoma of the colon in Crohn colitis is 4-20 times that of the general population. Small intestinal carcinoma is 50-100 times more likely to develop in patients with small intestinal Crohn disease but is still rare.

The risk for children with an onset of disease in the first decade is unknown, but children who develop colitis when younger than 10 years should undergo colonoscopic screening during adolescence.
