Данное заболевание характеризуется неблагоприятным прогнозом, обусловленным поздней диагностикой, быстрым прогрессированием и ограниченной эффективностью существующих терапевтических подходов. Цель данной работы — систематизация современных данных по диагностике и лечению РИАС на основе обзора литературы и анализа клинического случая пациентки, у которой заболевание развилось через несколько лет после лечения рака молочной железы. Несмотря на  проведенное радикальное иссечение, заболевание сопровождалось быстрыми рецидивами и  резистентностью к терапии, что подчеркивает сложность ведения таких пациентов. Представленный случай демонстрирует необходимость индивидуального подхода и дальнейших исследований для оптимизации лечебных стратегий.</p></abstract><trans-abstract xml:lang="en"><p>Radiotherapy-induced angiosarcoma (RIAS) of the breast is a rare but aggressive complication of radiation therapy that develops in patients following breast cancer treatment. This malignancy is characterized by a poor prognosis due to delayed diagnosis, rapid tumor progression, and the limited effectiveness of current treatment modalities. The aim of this study is to review modern approaches in the diagnosis and management of RIAS and to present a clinical case of a patient who developed RIAS several years following breast cancer treatment. Despite radical surgical resection, this case demonstrated rapid recurrence and resistance to therapy, highlighting the challenges in management. The presented case emphasizes the need for an individualized approach and further research to optimize treatment strategies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ангиосаркома молочной железы</kwd><kwd>радиоиндуцированная ангиосаркома</kwd><kwd>вторичное злокачественное новообразование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast angiosarcoma</kwd><kwd>radiation-induced angiosarcoma</kwd><kwd>secondary cancer</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">WHO Classification of Tumours Editorial Board.
