Breast angiosarcomas: A two case report

Angiosarcoma is a rare type of breast cancer; it has the worst prognosis of all breast malignancies and it is difficult to diagnose. Its definition is pathological; it is a primary malignant proliferation of endothelial cells of vascular tissue of the mammary gland. We report two cases of breast angiosarcoma observed at the Maternity of Oranges and at the National Institute of Oncology. The preoperative diagnosis was raised on the clinical and pathological data. The treatment was essentially surgical. The evolution was marked by complete remission in both cases. In light of these two observations and the literature review, we tried to update on the various aspects of this disease. © 2011 Springer-Verlag France.
