Psychogenic skin conditions of various types were observed with the following conclusions.

Psychogenic sensations and manifestations on the skin have always a meaning in relation to the total experience. The biological history and the life history determine the final shape into which psychosomatic irritation is built. Early organic disease offers the best basis for conversion later, but there must also exist a differential psychology for the various skin affections; e.g. sado-masochistic attitudes are found important in itching, and it has been observed that neurotic blushing and perspiration are related to paranoid conditions. Skin disease especially affects the individual's relation to others.
