Neurotic excoriations in Child
Repetitive skin-picking results in few to several hundred excoriations, scars, and scabs. The lesions typically exhibit delayed healing due to recurrent scratching.
There is a strong relationship between neurotic excoriations and underlying psychiatric disease, most often (OCD), depression, anxiety, and substance use disorder. Individuals who use recreational drugs, especially (crystal meth), are prone to neurotic excoriations. Pruritus-inducing drugs such as narcotics, especially , may result in neurotic excoriations as well.
In children and adults, skin picking is associated with developmental disabilities such as Prader-Willi syndrome. Systemic diseases such as type 2 diabetes mellitus and hepatitis C have also been reported to be associated with neurotic excoriations; however, the significance of this observation remains unclear.
