Bilateral Primary Breast Angiosarcoma: A Case Report

Angiosarcoma can develop in all parts of the body containing blood vessels, including breast. Statistically, less than 10% of all angiosarcomas originate in the breast. Angiosarcoma accounts for less than 0.05% of breast primary cancers. Primary angiosarcoma develops without a history of treatment for breast cancer, whereas secondary angiosarcoma develops in patients who have already had treatments for other primary breast cancer. In review of the literature, primary angiosarcoma, particularly bilateral, is rare. In this study, we present a patient, a young woman, with primary bilateral angiosarcoma. Although breast angiosarcoma is rare, we should be aware of it, particularly in young women with breast mass that is hyperflow in Color Doppler ultrasound.
