THE RELATION OF PSORIASIS TO ATTITUDE AND TO VASCULAR REACTIONS OF THE HUMAN SKIN

[摘要] A relation between stressful life situations and psoriasis was discovered in 9 of 10 patients studied. All patients for whom this relation was shown expressed the same attitude towards the stressful situation, a feeling that they were exposed to constant gnawing or irritation which they had to try to tolerate or put up with. Exptl. interviews showed a characteristic vascular change in the skin when patients were discussing those aspects of their lives which appeared to be relevent to the skin disease. This consisted of dilatation of arterioles together with increased tone of minute vessels. It is suggested that the site of predilection for lesions may be in part determined by chronic minor trauma, an illustration of Koebner''s phenomenon.
