description: "Benign vascular proliferations following external radiation. The lesions present in adults, predominantly in elderly women following radiotherapy for breast carcinoma. They arise from the radiated skin and are papules, small vesicles, or erythematous ecchymotic plaques with prominent telangiectasias. Identical lesions can occur after radiation for cervical carcinoma, endometrial carcinoma, ovarian carcinoma, Hodgkin lymphoma, and melanoma. There is an increased risk for subsequent development of angiosarcoma."
