Dermatology and conditions related to obsessive-compulsive disorder

Patients with cutaneous disorders may have obsessive-compulsive symptoms but treatment for these symptoms has been limited. Advances in our understanding of obsessive-compulsive disorders have led to the concept of a spectrum with similar phenomenology, underlying neurobiology, and psychopharmacotherapeutic response. Many of these disorders, which include trichotillomania, neurotic excoriation, onychophagia, body dysmorphic disorder, and dermatitis artefacta may respond to specific therapeutic interventions.
