Coexistent tuberculosis and carcinoma of the colon.

Colorectal cancer is currently ranked third in men after prostate and lung and second in women. Its association with inflammatory bowel disease is known. A cluster of case reports has accumulated on the coexistence of colonic carcinoma and tuberculosis (CTCC) in the same location. Association of long standing tuberculosis with cancer has been documented for many organs. We present a case report of coexistent carcinoma and tuberculosis involving the proximal colon and a review of literature.
