Pediatric Psychodermatology and Trichotillomania: Update on Strategies for Effective Treatment

This review serves as an update to our previous work on psychodermatology, a rapidly expanding sub-specialty that explores the intersection of dermatologic and psychiatric disorders. Since the initial publication, few developments have emerged in the management of key conditions such as delusions of parasitosis, trichotillomania (TTM), onychophagia, excoriation disorder, and body dysmorphic disorder, many of which frequently coexist with mood disorders. Specifically, TTM, classified under "Obsessive-Compulsive and Related Disorders" in the DSM-5, continues to present distinct challenges, especially in pediatric populations. Our updated review highlights the importance of a multidisciplinary approach involving dermatologists and mental health professionals, with a focus on integrating habit reversal therapy (HRT), cognitive behavioral therapy (CBT), and newer pharmacological treatments. As data on optimal treatment strategies remain limited, this paper emphasizes the necessity of individualized care to enhance patient outcomes, reflecting the evolving landscape of psychodermatology since our initial analysis.
