Multiple post-radiation angiosarcoma of the breast: rare clinical case

This article describes the rare clinical case of multiple radiation-induced angiosarcoma of the breast. Angiosarcoma is a rare, aggressive tumor originating from the endothelial cells of blood vessels that can affect internal organs, but the most common localization is the skin. The frequency of angiosarcoma development in the mammary gland is less than 1% of all malignant tumors of this localization. There are primary and radiation-induced (secondary) angiosarcomas. The reason for describing this clinical case is the rarity of this pathology, relatively little experience in the diagnosis and treatment of radiation-induced angiosarcoma both in our country and abroad.
