Anatomically Optimizing Reirradiation

Within the context of the presented case, the patient likely developed radiation-associated angiosarcoma (RAA).1 The timeframe fits because most cases of RAA occur between 2 to 12  years postradiation. Additionally, the clinical features are consistent with RAA, which usually develops in the dermis of the radiated skin. In contrast, primary angiosarcoma more commonly develops in the breast parenchyma.2 We counsel patients who present for postoperative radiation to the breast that the risk of developing radiation-induced malignancy in the treatment field is about 1 in 1000 to 1 in 10,000 over 10 years.
