Primary and secondary angiosarcoma of the breast
Angiosarcoma is a rare soft tissue tumor of the breast. It occurs in both a primary form without a known precursor, and a secondary form that has been associated to a history of irradiated breast tissue. These forms differ in many ways including median age, precipitating factors, and presentation. Both forms have a malignant behavior and a poor prognosis. The endeavor of this paper is to review what is known about the presentation, diagnostic and therapeutic modalities to date.
