Triple synchronous malignant tumors of colon, appendix and liver: a case report with literature review

Synchronous cancers are defined as malignant tumors that occur simultaneously. Each tumor must be primary which eliminate the possibility of being metastatic lesion of the other. If three separate organs are involved, that is so-called triple synchronous malignancy with very low morbidity. We report a case of a 33 year old male patient with triple synchronous malignancies at the colon, appendix and liver.
