Habit nail tic disorder: onychotillomania involving thumbs and toes responding to fluoxetine. International Journal of Research in Medical Sciences. 2024 May; 12(5): 1735-17372320-60712320-6012https://imsear.searo.who.int/handle/123456789/234096Habit nail tic disorder is a type of nail dystrophy caused by repetitive trauma to the nail matrix. It is a body-focused repetitive behavior that is commonly reported among adults and may or may not be associated with obsessive-compulsive behavior. In this report, we present a case of a 12-year-old adolescent girl who had a central furrow with longitudinal ridges running parallel from the proximal to the distal end of both her thumbnails and toenails, giving them a "washboard" appearance and diagnosed as habit nail tic disorder, and treatment involved fluoxetine 20 mg and the application of permeable adhesive tape to protect the nails from external trauma. There was a positive response observed two months after the beginning of the treatment and the nail matrix resolved spontaneously.OnychotillomaniaBody focused repetitive behaviourFluoxetineJournal ArticleIndiaDepartment of Psychiatry, Medical College and Hospital Kolkata, Kolkata, West Bengal, IndiaDepartment of Psychiatry, Medical College and Hospital Kolkata, Kolkata, West Bengal, IndiaDepartment of Psychiatry, Medical College and Hospital Kolkata, Kolkata, West Bengal, IndiaDepartment of Psychiatry, Medical College and Hospital Kolkata, Kolkata, West Bengal, IndiaDepartment of Psychiatry, Medical College and Hospital Kolkata, Kolkata, West Bengal, India
