ABSTRACT

Angiosarcoma is a rare, highly malignant endothelial cell carcinoma. Radiotherapy on breast cancer increases the risk of developing an angiosarcoma. We report an extremely rare case of bilateral breast radiation-associated angiosarcoma (RAA). Patient had a strong breast cancer family history, and genetic testing identified KRAS, PIK3CA, RPTOR, and VHL mutation, along with MYC amplification. The overall prognosis of RAA is poor as RAA is characterized by early metastasis, frequent local recurrence, and short overall survival time. The patient eventually passed away because of breast cancer metastasis to the lung and liver.
