Since the reports of cases of neurotic excoriations by MacKee1 and Pusey and Senear2 in 1920, a number of papers dealing with this disease have appeared in the American literature. Consequently every dermatologist is familiar with the characteristics of the disease and readily distinguishes it from the much less common condition dermatitis factitia. Neurotic excoriations are commonplace in dermatologic practice. Tomlinson and Cameron stated that cases of this condition comprise 2 per cent of the cases in their practice.3 The various factors which the patient produces usually with the aid of an instrument, such skin without any intent to deceive are well recognized by all observers.
In the vast majority of cases of neurotic excoriations, the lesions, whether few or numerous and whether localized or generalized, are simple, presenting only excoriations. These are produced when the patient has an irresistible impulse to pick, scratch or rub sites
