Dermatitis artefacta: a review.

Dermatitis artefacta is a rarely diagnosed disorder that is often a source of perplexity and anxiety for dermatologists because they know less about the cause of this self-inflicted condition than the patients themselves. It differs from other skin disorders in that diagnosis is made by exclusion rather than on the basis of histologic and biochemical findings and therefore involves a considerable investment of time and resources. Based on the findings of a study of 201 patients diagnosed with dermatitis artefacta between 1976 and 2006, we review the different clinical presentations of this skin disorder and discuss its diagnosis and treatment. The series analyzed comprised 152 women and 49 men (female to male ratio of 3.1:1) with a mean age of 31.2 years. The patients were mostly single and had a low educational level and few or no job qualifications or skills.
