[Carcinoma of the colon coexisting with tuberculosis--report of 2 cases].
Two cases of colon carcinoma coexisting with tuberculosis are reported. Both carcinoma were adjacent to scarring areas of ulcerative tuberculosis, these areas were covered by regenerated mucosa, the muscularis mucosae were lacking and there was occurrence of atypical regenerative tubules and adenomatous glands. These findings suggest that ulcerative lesions of tuberculosis may be precursors of the carcinomas. It is interesting that such carcinomas derived from a chronic inflammatory process with repetition of erosion, ulcer and consequent regeneration.
