Abstract

Double primary cancer is defined as the case of primary malignant tumors, which must be arise in different sites and have a different histologic appearences. The number of reported cases of double primary malignant tumors has increased in recent and the occurrence of multiple primary cancers in the same individuals is one of the interesting subjects for investigation and research in relation to the carcinogenic mechanism and/or genetic factors. We have experienced a case with double primary malignant tumors of different site origins such as stomach adenocarcinoma and rectal adenocarcinoma, which were diagnosed by biopsies with gastro and colono fiberscopy. For its great rarity, we report this case with review of literatures.
