Secondary angiosarcoma in a hormone receptor negative breast cancer patient.

Post-irradiation angiosarcoma arising in the irradiated breast after breast-conserving surgery is uncommon though being reported with increasing frequency. Such cases are reported mainly in hormone-receptor positive patients who had received hormonal therapy along with radiation. We describe a rare case of post-irradiation angiosarcoma in a 71-year-old hormone-receptor negative female who did not receive hormonal therapy.
