Cardiac Angiosarcoma : Gross Features

Cardiac angiosarcomas can range from 2 to 15 cm (mean size around 7 cm) at presentation. Grossly, it appears as dark, red-brown, hemorrhagic, solid or spongy mass with areas of softening due to necrosis. Less commonly, it is ill-defined infiltrative lesion. The pericardium may be thickened or discolored if it is invaded by the tumor (as seen here). Image copyright: pathorama.ch.
