Late isolated metastasis of colon adenocarcinoma to the right ventricle

Abstract

Cardiac malignancies are exceptionally rare, mostly occur as secondaries of lung, esophageal tumors, or lymphomas in the context of systemic illness, and usually found on autopsy. We present an exceedingly rare case of solitary metastasis of mucinous adenocarcinoma occupying 80% of the right ventricle and involving tricuspid valve, discovered 17years after a diagnosis and treatment of a colon cancer. The patient's clinical presentation, diagnosis, and surgical management are detailed. This case provides evidence that late metastasizing colonic carcinoma and ventricular location of metastasis can and do occur.
