Factitial dermatitis - Skin in Adult
Dermatitis-like lesions, panniculitis, ulcerative disease, and vasculitis-like lesions are all possible. The diagnosis of self-abuse tends to occur more frequently in women and in those working in health care. The psychological profile of the patient with self-induced skin disease is the patient with a dependent and manipulative personality or borderline personality disorder.
The patients' typical lack of concern for how disfiguring their lesions appear is out of proportion to the reality of their presentation. The patient history never seems to add up to explain the unusual cutaneous findings. This so-called "hollow history" is a characteristic of the disease. The lesions may be produced by scratching, picking, biting, cutting, burning, injecting, and puncturing. More serious wounds can be complicated by gangrene, abscess formation, or other life-threatening infections. Treatment is often challenging and multidisciplinary.
