[Radiotherapy of blastomatous hemangiomas - under special consideration of 44 eyelid hemangiomas (author's transl)].

The propriety of blastomatous hemangiomas to show spontaneous regression is underlined. Under certain indications, above all in case of eyelid hemangiomas, a radiotherapy is indicated. The moment of manifestation lies within the first three months of life, and the female sex is affected two times more frequently. The head represents the predilection spot within the distribution scheme of hemangiomas. 44 patients with eyelid hemangiomas who had been treated between 1968 and 1972 by the described irradiation method had check-up appointments five years later. The therapeutical results were evaluated according to certain criteria. 95,5% of the blastomatous hemangiomas showed a very good or satisfactory regression. Only 4,5% did not present any satisfactory success. In an advanced age of the patients, the hemangiomas do not always respond favourably to radiotherapy. In case of a strictly executed indication and a faultless irradiation technique, irradiation damages can be avoided. Our results show that, with regard to the spontaneous regression of blastomatous hemangiomas, total doses of 1000 to 1500 rd are sufficient. Finally the authors cite the standpoints of radiotherapy concerning the treatment of blastomatous hemangiomas and give recommendations for dosage principles.
