RIBEIRO, Maxwel Capsy Boga et al. Chagasic megacolon and large bowel neoplasms: case series and literature review. J. Coloproctol. (Rio J.) [online]. 2011, vol.31, n.4, pp. 372-377. ISSN 2237-9363. http://dx.doi.org/10.1590/S2237-93632011000400009.
There is a clear association between chagasic megaesophagus and the esophageal cancer. On the other hand, the association between chagasic megacolon and intestinal neoplasm is uncommon. There are only a few cases described in literature. We selected two cases of colorectal adenocarcinoma associated with adenoma from 2000 to 2011, which are added to the four patients already described by this group. The mean age of the patients, was 68.5 years. Both had been submitted to surgical resection of the neoplasm. Survival rates ranged and were directly related to tumor staging at the time of diagnosis. In this context, we report our case series and reviwed the corresponding literature, especially the clinical and epidemiological aspects of this rare association.
