====Images====
Angiosarcoma of right atrium. A. Luminal clot tops tumor with blood filled spaces. B. Tumor replaces myocardium. C. Irregularly branched vessels, sometimes associated with extravasated erythrocytes. D. Irregularly aggregated and oriented spindle cells. E. Cells vary in size and shape much more so than an organizing thrombus or hemangioma. Note luminal tufts (green arrows), clustered large cancer nuclei with nucleoli (blue arrows). F. Cytoplasmic vacuoles, some with erythrocytes (arrows).
