Breast Angiosarcoma: Four Case Series and Literature Review.

Abstract

The mammary angiosarcoma is a rare malignant mesenchymal tumor that develops from the vascular tissue of the breast. It represents 0.004 to 1% of all malignant breast tumors and 8 to 10% of breast sarcomas. It can be primary in a 40-year-old woman or radiation-induced in an older woman who has undergone conservative treatment for breast cancer, including conservative surgery and adjuvant radiotherapy. Herein, we present four cases involving breast angiosarcoma in young and relatively older women and the different treatment they received. Our discussion encompasses the epidemiological, diagnostic, and therapeutic facets of this rare and aggressive tumor type.
