Tuberculosis can involve any part of the gastrointestinal tract but 80∼90% of patients<br>present the disease in the ileocecal region. The cases of colon cancer coexisting with colonic<br>tuberculosis are relatively rare and ascending colon is the predominant site of the combined<br>disease. A 46-year-old man, without specific past medical or family history, showed multiple<br>colonic polyps and ulcers on colonoscopic examination. After surgery, the surgical specimen<br>disclosed adenocarcinoma in the ascending colon, eleven adenomatous polyps throughout the<br>colon, and multiple tuberculous ulcers in the entire colon. Tuberculosis of terminal ileum was<br>also accompanied. The association of colonic tuberculosis and colon cancer with multiple<br>polyps in this case may have been coincidental. The preoperative colonoscopic examination<br>and pathologic diagnosis by frozen section during operation are necessary for the adequate<br>treatment.<br>
