Primary angiosarcoma of the breast: a case report and review of the literature.

Primary angiosarcoma of the breast is rare. Therefore, no randomized trial can be used as guideline for diagnosis and treatment. To achieve optimal outcome, previous reports of case series are the sources for management with expected long-term survival. The objective of the present case report is to demonstrate complete pathologic response to neoadjuvant taxanes without recurrence after two years of follow-up.
