Cardiac metastases are among the topics with limited systematic reviews. Theoretically, the heart can be infiltrated by any malignancy with the ability to spread to distant structures. Thus far, no specific tumors are known to have a predilection for the heart, but some do metastasize more often than others, for example, melanoma and primary mediastinal tumors. We report a case of cardiac metastasis from a diffuse large B cell lymphoma in a young man. The peculiarity of this case is that besides the involvement of right ventricle and atrium, the tricuspid valve was also infiltrated. Valvular metastasis is rarely reported in the medical literature.
心脏转移瘤是系统评价有限的主题之一。理论上，任何具有扩散至远处结构能力的恶性肿瘤都可侵犯心脏。迄今为止，尚无已知特定肿瘤对心脏具有偏好性，但有些肿瘤发生转移的频率高于其他肿瘤，例如黑色素瘤和原发性纵隔肿瘤。我们报告一例年轻男性弥漫性大B细胞淋巴瘤发生心脏转移的病例。该病例的独特之处在于，除右心室和右心房受累外，三尖瓣也受到侵犯。瓣膜转移在医学文献中鲜有报道。
