I am not familiar with any searching study of the amount of irradiation necessary, the exact time sequences for development of telangiectases, or the reactivity or susceptibility of the skin in different parts of the body or in different persons. Lewis, among others, discussed the great variability of these telangiectases and tested their reactivity to adrenalin and histamine, but his organizing mind never came to grips with the essence of the problem. It does not seem to have excited the attention of any perceptive radiologist to make systematic studies and so has gone by default.3 This note describes observations I made of a woman who developed radiation telangiectases which were especially numerous and large in the periumbilical region and in
