The occurrence of synchronous but unrelated cardiac and colorectal tumors is extremely rare. We present the case of a 56-year-old man who had a left atrial cardiac myxoma that nearly obstructed the mitral valve outflow tract and an unrelated, synchronous colorectal-vesicle carcinoma that nearly obstructed the lumen of the intestine. The patient underwent emergency resection of the cardiac mass under cardiopulmonary bypass and underwent successful resection of the colorectal mass 2 weeks later Two years after these operations, the patient is well with no recurrence of either tumor Synchronous tumors, particularly when one of them involves the heart, require aggressive surgical treatment at multiple sites in order for the patient to survive.
