Cardiac neoplasms are a rare occurrence in clinical practice. The various frequencies of primary and secondary malignant tumors vary from report to report, approximately 1% in most autopsy series and 4% in cancer patient's autopsies. Cardiac malignancies account for less 1% of cardiac surgery and about for 0.1% of cardiac echographic studies. The presence of metastatic tumor to the heart usually indicates widespread metastases. Lung carcinomas are the most commonly encountered tumor followed by breast and pancreas cancer and melanoma. Apart from primary pericardial mesothelioma, primary cardiac tumors are high-grade sarcomas with a high metastatic potency that often becomes evident early after surgery. Symptoms are non specific, occur late in the disease and affect few patients; especially secondary neoplasms of the heart take their course so fast that they cannot become symptomatic. The signs of cardiac neoplasms are divided into systemic symptoms (fever, arthralgias and myalgias), cardiac symptoms (congestive heart failure, arrhythmia, chest pain) and uncommon embolisms. Diagnosis is actually made easier with cardiac echography. Cardiac RMI is helpful to estimate vessels and pericardium involvement. Due to its poor prognosis, treatment of cardiac metastases is restricted to best supportive care. For primary cardiac neoplasms, surgery must be carefully discussed because operative intervention is often followed by rapid widespread metastases that adjuvant chemotherapy cannot avoid in most cases.

Primary and secondary neoplasms of the canine and feline heart are uncommon. During a 2-year period, 83 dogs suffering from primary cardiac (n=11), extracardiac benign (n=6) or malignant (n=66) tumours and 30 cats with primary cardiac (n=1) or extracardiac (n=29) malignant tumours were examined. Echocardiography revealed four cases of primary cardiac neoplasms in dogs, but secondary heart tumours were not detected. After necropsy, tissue samples from the heart and tumours were examined histologically and immunohistochemically. In dogs, primary neoplasms included seven haemangiosarcomas, two chemodectomas, one rhabdomyosarcoma, and one neurofibrosarcoma. In 24 of 66 dogs examined, metastases of extracardiac neoplasms were found in the heart (15 carcinomas, six malignant lymphomas, three haemangiosarcomas). In cats, one case of primary haemangiosarcoma of the pericardium and five cases of secondary cardiac tumours (two malignant lymphomas, three carcinomas) occurred. Cardiac neoplasms in cats were not identified clinically but were detected by detailed gross sectioning of the heart (n=2) or histopathological examinations (n=3). This study showed an unexpectedly high number (36%) of dogs with cardiac metastases.

Cardiac neoplasms, whether primary or secondary, are more and more easily diagnosed in the present era. For the primary heart tumors, myxomas and sarcomas constitute the most common neoplasms, whereas for the secondary ones, lung cancer constitutes the most common primary location. Cardiac neoplasms may involve the endocardium, the myocardium, the epicardium, the valves or any combination of these. Their clinical manifestations are not specific and depend on their anatomic location and size. Diagnosis of cardiac neoplasms has become more feasible with the use of echocardiography and other imaging techniques (computed tomography and magnetic resonance). The major problem, however, still remains that most diagnoses are late, especially for malignant tumors. For resectable tumors, surgery remains the mainstay of treatment, whereas for metastatic disease palliative treatment remains the only therapeutic option. This paper reviews the types of heart tumors, their clinical symptoms, the diagnostic approaches and the therapeutic tools used by physicians.

Cardiac mass can be described as an abnormal structure within or directly contiguous to the heart. Tumors and thrombi are the most common types of cardiac masses. Intracardiac thrombi have been encountered in various clinical settings and can result in severe morbidity and mortality due to embolic events. Cardiac neoplasms are extremely rare, and are usually metastatic tumors. The major primary malignancies associated with cardiac metastases include cancers of the lung, breast, stomach, and liver, and lymphoma, leukemia, and melanoma. Osteosarcoma (OS) is the most common type of bone malignancy, and is almost always highly malignant. A previous study demonstrated that OS very rarely metastasizes to the heart. Presently reported is an unusual case of OS with intracaval, right atrial, and right ventricular extension that was misdiagnosed as venous thrombus.
