    TLDR Many skin patients have mental health issues, but few dermatologists are well-versed in treating these conditions.
    The 2017 document reviews psychocutaneous diseases, which are psychiatric disorders with skin manifestations, and their prevalence in dermatological settings. It notes that 30% of dermatology outpatients have psychiatric comorbidities, but many refuse psychiatric care, leaving dermatologists to manage their conditions. Despite this, only 18% of dermatologists have a clear understanding of psychodermatology, and 42% feel comfortable diagnosing and treating these disorders. The review covers common psychocutaneous syndromes, updated classifications from DSM-5, and management strategies, highlighting the importance of building a therapeutic alliance and using antipsychotic medications and psychotherapy. It also discusses specific disorders like excoriation disorder, trichotillomania, BFRBD, and BDD, providing prevalence rates, typical onset ages, and effective treatments such as behavioral therapy, N-acetylcysteine, and SSRIs. The document emphasizes the need for proper diagnosis and treatment due to the significant distress and impairment caused by these disorders.
