title: Fine-needle aspiration of metastatic radiation-induced cutaneous epithelioid angiosarcoma of the breast to the liver: A diagnostic dilemma.
abstract: Radiation therapy is a significant risk factor for the development of angiosarcoma. With the increase in breast conservation treatment, the incidence of cutaneous radiation-induced angiosarcoma of the breast is rising. If the angiosarcoma demonstrates epithelioid features, the tumor cells may present a diagnostic dilemma on fine-needle aspiration cytology. We present a case of metastatic radiation-induced cutaneous epithelioid angiosarcoma of the breast to the liver and a review of the literature.
