A case of colonic carcinoma associated with intestinal tuberculosis, and an analysis of 26 cases reported in Japan

A case of tuberculosis and adenocarcinoma co-existing in the ileocecal region in a 61-yr-old woman is described. The Japanese literature is reviewed and several points discussed regarding the epidemiological and morphological features in a colon carcinoma associated with tuberculosis. (1) Females predominate by a ratio of 17:9 in such cases. (2) The tumor has been found in the right side of the colon in 17 out of 26 cases. (3) The most characteristic histological finding is that of the cancer, which shows a well differentiated adenocarcinoma with a tendency to produce a mucin. These unique findings are consistent with those in our case. It is of interest that these unique findings may support the possibility that the cancer originated from a tuberculous lesion.
