Pathologic grooming (acne excoriee, trichotillomania, and nail biting) in 4 generations of a single family

Trichotillomania (hair pulling disorder), excoriation (skin-picking) disorder, and other body-focused repetitive behavior disorders (BFRBDs) have received increasing attention in the psychiatric nomenclature. Trichotillomania was introduced in the Diagnostic and Statistical Manual of Mental Disorders (DSM) in DSM-III-R in 1987, whereas skin-picking disorder was introduced in the most recent edition of the manual, DSM-5.1 DSM-5 includes both disorders and also refers to other less well-studied BFRBDs, such as nail biting, in a new chapter on obsessive-compulsive and related disorders.
