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.
原发性心脏肿瘤并不常见。然而,影响心脏的转移性肿瘤却更为常见。尸检研究表明,一些肿瘤报告继发性心脏转移率超过50%。对于有肿瘤病史且出现传导障碍、杂音、心脏扩大或心律失常的患者,应考虑到这种累及情况。本文报告一例39岁男性患者,因疲劳和劳力性呼吸困难前来就诊。超声心动图证据显示右心室有巨大肿瘤块。病史显示既往有黑色素瘤;进一步评估显示已转移至肺、心脏和脑。结局是死亡。该病例的独特之处在于右心室有巨大转移瘤块,从而说明了一种预后不佳的罕见临床情况。
