[Regression of haemangiomata in infants after x-ray treatment and mock-radiation (author's transl)].

In the years 1966-1969 100 haemangiomata which had developed in early childhood were prospectively investigated in a randomised study. Half of them were treated by soft X-ray radiation, the other half underwent mock-radiation as a control. 54% of the original group could be examined after 6 years. The results showed that the ratio of cure was similar in the both groups. The skin pattern of the incompletely cured haemangiomata was also comparable. The biological rule of regression of haemangiomata in early childhood seems not to be influenced by X-ray treatment. It is striking that X-ray treatment in dark-skinned children leads to a better therapy-result than in fair-skinned ones.
