Snapshot A 5-year-old boy is brought to the pediatrician’s office for evaluation of “white patches.” His mother is worried that he has vitiligo. These white patches started a few weeks ago after a month-long summer camp. The child has a history of atopic dermatitis and severe food allergies. On physical exam, he has multiple 1-3 cm irregular but well-defined patches of hypopigmentation on his cheeks, upper arms, and chest. There is overlying scaling and minimal erythema. His mother is counseled about the benign nature of this disease and recommends topical moisturizers and topical corticosteroids to minimize symptoms.
