Snapshot A 16-year-old boy presents to the clinic for an itchy rash on his hands. He reports he is concerned because of an ongoing pandemic, and he cannot help but wash his hands every hour while awake, even if he did not leave the house or touch anything dirty. He reports being very preoccupied with thoughts of having “dirty” hands filled with microorganisms and feels partial relief when he washes his hands thoroughly with soap and water. On exam, he has pink scaly plaques on his hands and tiny vesicles along the lateral fingers, consistent with hand dermatitis. He is prescribed a strong topical steroid cream and referred to psychiatry for management of suspected obsessive-compulsive disorder.
