It is a rare, aggressive malignancy that affects young people, most commonly in the second decade of life. The treatment of localized disease has improved greatly over the past four decades, but the prognosis for metastatic disease remains poor. Cardiac metastases of Ewing's sarcoma are exceedingly rare, with only a few reported cases.
