Neurotic excoriations.

Neurotic excoriations are self-inflicted skin lesions produced by repetitive scratching. Because there is no known physical problem of the skin, this is a physical manifestation of an emotional problem. The classic lesions are characterized by clean, linear erosions, scabs and scars that can be hypopigmented or hyperpigmented. The lesions are usually similar in size and shape, and are grouped on easily accessible and exposed body sites, such as extensor surfaces of the extremities, face and upper back. Psychotropic medications and appropriate counseling can be effective treatments.
