A rare type of trichotillomania: rhinotillexomania

Trichotillomania (or hair-pulling disorder) is a psychiatric disorder characterized by repetitive chronic hair pulling that can result in serious hair loss. While having been familiar for many years, little is known about its epidemiology, etiology, and subtypes. In the DSM-IV-TR, trichotillomania was classified as an impulse-control disorder (1), whereas in the DSM-5, it falls under the new category of Obsessive-Compulsive and Related Disorders (2). Epidemiological studies of trichotillomania are limited, but current prevalence studies suggest that it is a common disorder (3)
