Background Repetitive skin focused behaviors, such as nail biting, hair pulling, cutting, and others may involve brain regions that participate in visual and tactile awareness, contextual learning and anxiety. Methods Gender and age of onset were collected on 78 patients with a repetitive skin focused disorder from a general dermatology clinic between 2014-2018. The disorders included onychophagia (nail biting), trichotillomania (hair pulling), cutting, pathologic skin picking, acne excoriée (popping pimples) and delusions of infestations. Results Sixty/Seventy-eight, (77%) of the patients were female. Onychophagia, trichotillomania, and cutting emerged during key developmental milestones, such as adrenarche and pubarche. The 17 patients with delusions of infestations were middle-aged, between 52-66. Five/Seventy-eight (6%) attempted suicide, all female, three successfully. Conclusions Repetitive skin focused behaviors may reflect potentiation in neural circuits that participate in contextual processing, tactile and visual awareness. Trends emerged in gender predominance and age of onset. These disorders may have clinical utility in two key areas, emotional regulation in teenagers and drug toxicity in adults.
