Polyposis coli associated with adenocarcinoma of the gallbladder. Report of a case.
A case of malignant polyposis coli, occurring in a 71-year-old man in association with a primary invasive adenocarcinoma of the gallbladder is presented. The eventuality that the carcinoma of the gallbladder could be a metastasis from the colonic neoplasia was excluded due to the observation in the mucosa of the gallbladder of changes corresponding to carcinoma in situ. This is the fourth case reported of polyposis coli coexisting with a carcinoma of the biliary tract.
