Cutaneous angiosarcoma of the breast after segmental mastectomy and radiation therapy.

Angiosarcoma of the breast is an uncommon entity, and the development of cutaneous angiosarcoma of the breast after segmental mastectomy and irradiation therapy is even less common. We report a case of cutaneous angiosarcoma that developed 4 1/2 years after segmental mastectomy (lumpectomy) with axillary dissection and irradiation therapy for infiltrating ductal carcinoma of the breast.
