A case of angiosarcoma of the scalp.

Angiosarcoma of the scalp is a relatively rare skin malignant disorder. We experienced a case of angiosarcoma. A 74-year-old woman admitted our hospital with a tumor which had appeared 1 month before on her right frontal scalp. Three months ago she got injures for two times on the scalp where exact same place the tumor appeared. She was diagnosed as angiosarcoma by typical clinical and histopathological features. She was intensively treated with rIL-2 and surgical operation. Intra-arterial infusion of rIL-2 was carried out before the operation. After the operation she was treated with intra-venous infusion of rIL-2. At the time of beginning the treatment, diameter of the tumor was 5cm and decreased to 3cm just before the operation. We estimated the IL-2 therapy benefitable for decreasing the tumor-size. No recurence is observed until now. [Skin Cancer (Japan) 2000; 15 : 276-279]
