1. Abstract

Angio Sarcomas (AS) are rare tumors, accounting for about 1% of soft tissue sarcomas.

Mammary AS can be separated into two categories: primary AS, occurring in the breast parenchyma, and secondary AS, which usually develop in the skin, or sometimes in the chest wall or breast parenchyma following treatment. by surgery and radiotherapy for breast cancer. Both forms behave badly and have a poor prognosis. We report a case of angiosarcoma of the breast diagnosed by histology and the treatment consists of a mastectomy supplemented by chemotherapy and radiotherapy.
