Primary Psychiatric Disorders: Dermatology Perspectives

ABSTRACT: Psychodermatology is a rapidly evolving field of dermatology that bridges dermatology, clinical psychology, and psychiatry. Psychodermatological disorders comprise a significant proportion of dermatological consultations, with varying prevalence across clinical settings. Numerous classification systems exist for psychodermatological disorders. The recent international consensus has established comprehensive multidimensional frameworks. This review focuses on primary psychiatric disorders, which have a psychiatric etiology but manifest on the skin and mucosae. This group includes disorders ranging from delusional infestations and body dysmorphic disorder to body-focused repetitive behaviors and self-induced skin lesions. Each condition is discussed comprehensively, incorporating contemporary diagnostic frameworks from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and the International Classification of Diseases, 11 th Revision (ICD-11), alongside evidence-based treatment modalities. A multidisciplinary, biopsychosocial approach integrating dermatological and psychiatric care is central to effective management, utilizing pharmacotherapy, cognitive behavioral therapy, and supportive psychotherapy while addressing the dermatological aspects.
