[Radiation-induced breast angiosarcoma: about a case].

Breast angiosarcoma is a rare vascular endothelial connective tissue tumor. It is primitive in young patients and radio-induced in older subjects. It is a malignant tumor and it manifests with polymorphic clinical and radiological features. Its prognosis is poor due to the frequent occurrence of visceral metastases and fast recurrence. We here report a case of breast angiosarcoma in a female patient aged 43 years, with a history of breast cancer, treated by conservative surgery and adjuvant radiotherapy. The purpose of this study is to highlight the epidemiological diagnostic and therapeutic features of these rare aggressive tumors.
