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