[Angiosarcoma of the breast]

A painless ecchymotic plaque developed progressively on the right breast of a 16 years old girl. Failure of the first biopsies to bring up specific lesions and episodes of regression delayed the diagnosis until a very deep biopsy and a CT-scan investigation revealed a diffuse and malignant vascular process. A simple mastectomy did not prevent recurrence and metastasing 3 months later. The clinical aspects of breast angiosarcoma, the shortcomings of investigative procedures and the recommended therapeutics are reviewed.
