Inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, has a potential risk of developing into colorectal cancer. However, there is little relationship between intestinal tuberculosis and colon cancer because intestinal tuberculosis is a curable disease and has a relatively short disease course. Nevertheless, there have been a few case reports of intestinal tuberculosis associated with colon cancer. There was a case report in which the carcinoma facilitated entry of tubercle bacilli with development of a secondary infection, and ulcerative lesions of tuberculosis may be precursors of carcinomas. We experienced a 77-year-old woman who had intestinal tuberculosis combined with ascending colon cancer. She visited our hospital because of abdominal pain and constipation. Colonoscopy showed a luminal obstruction mass in the ascending colon. Histologic examination revealed an adenocarcinoma. After surgery, the surgical specimen disclosed an adenocarcinoma in the cecum and ascending colon and intestinal tuberculosis around the cancer site of the cecum. Herein, we report a rare case of colon cancer co-existing with colonic tuberculosis with a review of the literature. J Korean Soc Coloproctol 2007;23:194-198
