Abstract

Two cases of primary malignant cardiac neoplasms are presented. The first, an angiosarcoma of the right atrium, developed in a 44-year-old housewife, who survived 23 days from the time of presentation; diagnosis was made at necropsy. The second, an embryonal rhabdomyosarcoma of the right ventricle, developed in a 17-year-old student; diagnosis was made by angiocardiography. He underwent surgery and cytotoxic and irradiation therapy and died 14 months later.
