Several months after left radical mastectomy without irradiation therapy for breast cancer, a 74-year-old woman developed severe edema on the homolateral arm extending to the axilla. Ten years later, purplish to brownish blotch and nodules accompanied with heating sensation and pain appeared and increased in size gradually on the left forearm. The patient was treated by irradiation therapy under the clinical and histopathologic diagnosis of Stewart-Treves syndrome and almost all of the skin lesions and symptoms disappeared after irradiation of 6450 rads.

A 29-year-old pregnant woman with recurrent pericardial effusion and a cardiac tumor, diagnosed as an angiosarcoma, was treated with surgical resection of the tumor followed by radiotherapy. Immediately after completion of radiotherapy, she developed bilateral breast masses, which were also confirmed as angiosarcomas. We thought this might be the first case of bilateral angiosarcoma of the breast metastasizing to heart mimicking a primary cardiac angiosarcoma, although we could not conclude with certainty that angiosarcoma of the heart was not the primary site.
