Epitheloid hemangioendothelioma of the heart in infancy.

We report a case of primary cardiac epithelioid hemangioendothelioma arising from the right atrium of a 2-month-old infant. The tumor was found incidentally during exploratory sternotomy for recurrent pericardial effusion. This case represents a very rare situation, because this is the youngest patient found in relevant literature, and because it involves extensive infiltration by the tumor without any development of intracardiac mass appearance.
