RESUMO
Soft tissue sarcomas represent rare tumors. They recur most often locally and in the lungs. We report the case of a 58-year woman who was treated for awith chemotherapy and then surgery. About a year after the end of the treatment an intracardiac mass was identified during a follow up chest CT-scan. The patient underwent a surgical resection of that mass found to bel myxoid chondrosarcoma metastasis. Only 2 cases of cardiac dissemination of extraskeletal myxoid chondrosarcoma have been described. The differential diagnosis of intracardiac masses is discussed. In some carefully selected cases atrisks of obstructive shock or embolization and unique metastatic location, cardiac surgery should be considered.

Though acute myocardial infarction is one of the most frequent causes of ST segment elevation, there are other, less frequent, reasons for such electrocardiographic changes. In the present case, a cardiac metastasis from a squamous cell lung carcinoma was responsible for these changes. The secondary lesion was located in the apex of the left ventricle and induced an ECG alteration mimicking myocardial ischaemia. The literature includes few reports that describe the relation between electrocardiographic changes and heart metastases, since heart metastases are not usually discovered except at autopsy.
