Primary cardiac malignancy is very rare. The most common malignant cardiac tumours are angiosarcomas. Their diagnosis is sometimes difficult because of their nonspecific clinical presentation. Two cases of primary cardiac angiosarcomas that were not diagnosed clinically due to unusual presentations are presented. Pathological diagnosis was missed in one case because of lack of thorough examination and sampling of submitted specimens. Cardiac symptoms in a patient with primary angiosarcoma of the heart may not always be present. In the presence of unusual serious systemic symptomatology, such as multisystemic hemorrhagic phenomena, disseminated infiltrative pulmonary lesions or peripheral tumour associated with subtle heart abnormalities, the possibility of cardiac angiosarcoma should be included in the differential diagnosis.
原发性心脏恶性肿瘤非常罕见。最常见的恶性心脏肿瘤是血管肉瘤。由于其临床表现不具特异性，有时诊断较为困难。本文报告了两例原发性心脏血管肉瘤，因其表现不寻常而未被临床诊断。其中一例因对送检标本缺乏全面检查和取样而漏诊病理诊断。心脏原发性血管肉瘤患者不一定总会出现心脏症状。当出现不寻常的严重全身症状，如多系统出血现象、弥漫性浸润性肺部病变或伴有轻微心脏异常的外周肿瘤时，鉴别诊断应考虑心脏血管肉瘤的可能性。
