Tumores digestivos simultáneos / Simultaneous digestive tumors

RESUMO

Synchronous and metachronous gastrointestinal tumors are well know entities, describing malignant tumors placed in the same organ, at the time of initial diagnosis or during the follow-up control. I would like to present two cases of malignant tumors placed in different organs of the digestive tube, at the time of diagnosis, coining the name simultaneous for these entities, stating laboratory finding and signo-symptomatologic interpretation difficulties, and proposing endoscopic approach as a valid diagnostic method.
