[Radiation therapy of keloids and hemangiomas (author's transl)].

Keloids and hemangiomas of the cavernous type which require treatment respond very reliably to X-rays. Adequate use of this therapeutic possibility offers considerable advantages to the patients in many cases and in addition it is without danger. Treatment of hemangiomas with beta radiation in the form of Sr-90/Y-90 plates for shortterm application to the skin is so safe and at the same time so successful that, in view of the not at all rare unfavorable spontaneous course, it seems rather risky to delay the indication to begin radiation therapy at the earliest possible moment.
