Extraosseous Ewing Sarcoma Presenting with Inferior ST-Elevation Myocardial Infarction and Systemic Emboli due to Tumor Thrombus and Invasion of the Left Atrium

Abstract

Extraosseous Ewing sarcoma is an uncommon entity in the adult population. Cardiac metastases or local invasion of a tumor into the heart is a known but also infrequent occurrence for most malignancies. We present a case of a patient with a history of extraosseous Ewing sarcoma who presented to the emergency room with chest pain and was found to have an inferior ST-elevation myocardial infarction and systemic emboli and was found to have recurrence of sarcoma invading the left atrium.
