Percent depth dose curves of Lineac electron beam and Dermopan soft X-ray, which are used for radiation therapy of surface tumors, were studied in 2 patients with angioblastoma (Nakagawa) who had been followed up for a long time after radiation therapy. The results are discussed with a review of the literature. Lineac electron beam therapy at low doses that do not cause remote complications appeared to be useful in the treatment of surface tumors selected after careful consideration of the indications.
