Right ventricular tumor in a patient with melanoma.

Primary tumors of the heart are not common. However, metastatic neoplasms affecting the heart are more commonly found. Postmortem studies have shown that some tumors have reported secondary cardiac implants to be over 50%. Such involvement is to be taken into account for patients with a history of neoplasm and who present conduction disorders, murmur, cardiomegaly or arrhythmia. This is to report the case of a 39-year-old man who had been referred due to fatigue and dyspnea on effort. Echocardiogram evidence showed large tumoral mass in right ventricle. Medical history showed previous melanoma; further evaluation showed metastasis to lungs, heart and brain. Outcome was death. The uniqueness in this case relies on the large metastatic mass in right ventricle, thus illustrating a rare clinical condition of guarded prognosis.
