Squamous cell carcinoma of lung atypically involving heart: A case report with literature review

Abstract

Cardiac metastasis usually appears in patients with disseminated tumor disease. Involvement of heart in malignancy is generally underestimated and found to be in up to 25% of post mortem patients who had died of cancer. Cardiac involvement in metastases is usually uncommon; however, it may present with tachycardia, arrhythmia, cardiomegaly, heart failure, dyspnoea, hypotension, and pulsus paradoxus. Right side of heart is commonly known to be involved and the order of frequency of malignancies to metastasize to layers of the heart is pericardium, myocardium and endocardium. © © The authors | Journal compilation © Cardiol Res and Elmer Press Inc
