Misdiagnosis: cardiac metastasis presented as a pseudo-infarction on electrocardiography.
Most tumor invasion into the heart is nonspecific and clinically silent. Myocardium metastasis rarely mimics a myocardial infarction. In this case, a cardiac metastasis from a squamous cell carcinoma presented with both persistent ST elevation and paroxysmal supraventricular tachycardia. The secondary lesion was located in the anterior wall and lateral wall of the left ventricle and induced electrocardiographic changes imitating an acute myocardial infarction.
