We report the case of an immunocompetent 83-year-old man with metastatic neoplastic infiltration of the heart from primary squamous cell carcinoma (SCC) of the skin. Death was from cardiopulmonary collapse due to left ventricular failure with features of right ventricular inflow tract obstruction. Metastatic tumours involving the heart rarely originate from cutaneous SCC though have been reported in the literature in both immunocompetent and postrenal-transplant recipient patients. Most involve the pericardium and only rarely the endocardium or the myocardium. While the prognosis is generally poor, palliative radiotherapy may provide significant symptom relief. Cardiac metastases should be considered in patients with advanced cancer, especially when they show cardiac symptoms and signs.
我们报告了一例83岁免疫功能正常的男性病例，其心脏出现了源自皮肤原发性鳞状细胞癌（SCC）的转移性肿瘤浸润。患者死于心肺功能衰竭，原因是左心室衰竭并伴有右心室流入道梗阻的特征。累及心脏的转移性肿瘤很少起源于皮肤SCC，尽管在免疫功能正常的患者和肾移植受者中均有文献报道。大多数累及心包，很少累及心内膜或心肌。虽然总体预后较差，但姑息性放疗可能会显著缓解症状。晚期癌症患者应考虑心脏转移，尤其是当他们出现心脏症状和体征时。
