Abstract
We report a case of a 90-year-old man with angiosarcoma on his scalp, effectively treated with electron beam irradiation. He was referred to our hospital for dusky erythemas and purpuras widely developed on his whole scalp. The lesion was diagnosed histologically as angiosarcoma. However the patient was injected with IL-2 (a total dose of 4.7 million units), and we observed significant eosinophilia and acute renal failure one week later after starting IL-2. Subsequently, he was treated with electron beam therapy (a total of 90 grays) . The lesions were effectively treated and almost disappeared. In this case, the radiotherapy was beneficial for his quality of life. [Skin Cancer (Japan) 2006; 21: 318-322]
