title: Angiosarcoma of the breast. Two case reports and a review of the literature.
abstract: Two cases of angiosarcoma of the breast are presented. They are of particular interest in that one patient is a long-term survivor, the 19th reported to date, and the other presented with contralateral breast involvement without evidence of disseminated disease. The world literature is reviewed and a discussion is presented of the clinical features, treatment, histopathologic features, and prognosis of this rare breast neoplasm. Tumor size and degree of tumor differentiation are the most important prognostic indicators, and in general a simple mastectomy is the treatment of choice. The value of adjuvant irradiation and chemotherapy is uncertain.
