Synopsis

Neurotic excoriations is a skin condition wherein the individual compulsively and habitually scratches and picks at their skin. Unlike patients with dermatitis artefacta, those with neurotic excoriations will usually admit their involvement in creating the lesion. There is a strong relationship between neurotic excoriations and underlying mental illness, most often obsessive compulsive disorder and depression. The disorder is predominantly seen in middle-aged females but can be seen in almost any age. The continued scratching can lead to the itch-scratch-rash cycle, further perpetuating the condition.

Individuals who take street drugs, especially methamphetamines (crystal meth), are prone to neurotic excoriations. Pruritus-inducing drugs such as narcotics, especially heroin, may result in neurotic excoriations as well.
