Primary angiosarcoma of the breast: A clinical case and review of the literature

We present here a rare case of primary mammary angiosarcoma in 48-year-old female patient. After 3 years without treatment, the woman presented to the hospital with locally advanced tumor in right mammary gland, involving the overlying skin and bleeding. Radical mastectomy was performed with axillary lymph-node dissection. The CT scan revealed solitary liver metastasis. After an overview of different cases of primary angiosarcoma of the breast published in the literature, we discuss the importance of histological criteria and immunohistochemical methods, as well as the optimal multimodal treatment in these patients. Poorly differentiated primary mammary angiosarcoma (grade 3) is an invasive neoplasm with high risk of local recurrence and distant metastases. The multimodal treatment involves radical mastectomy with or without axillary lymph-node dissection. Adjuvant radiotherapy and adjuvant chemotherapy help the local tumor control, reduce recurrences and increase overall survival.
