title: [Synchronous tumors of the gastrointestinal tract].
abstract: The term "synchronous tumors" is reserved for simultaneous evolution of two or more tumors with distinct sites, in which the possibility that one tumor is a metastasis of the other has been excluded. In medical practice, the involvement of two different cavitary organs of the gastrointestinal tract is very rare. We present two clinical cases of synchronous tumors: one of a malignant degeneration of a colonic polyp, associated to a jejunal tumor; the other of a patient with a gastric adenocarcinoma, who also had a bulky rectal villous tumor. We tried to find out the etiology of the tumors and the frequency of these associations, mentioned in medical literature. Immunohistochemistry investigations, genetic analysis and familial screening must complete an individualized medical approach in which the surgical technique must be adequate for each case.
