[Metachronous adenocarcinoma of the duodenum associated with previous colorectal carcinoma]

We present two patients who developed a carcinoma of the duodenum years after a colectomy was performed adenocarcinoma of the colon. Duodenal carcinoma has been reported in patients with villous tumor of the colon, familial adenomatous polyposis, Gardner's syndrome, celiac disease and Crohn's disease. A relationship between carcinoma of the Vater's ampulla and adenocarcinoma of the colon has also been reported. However, we have not found in the literature this association in patients without familial adenomatous polyposis or Gardner's syndrome.
