A2 - Appachi, Elumalai PY - 2015 T2 - The Color Atlas of Pediatrics AB - An 8-year-old Hispanic boy presents for evaluation of mildly itchy, pinpoint bumps that have been present for 2 to 3 months. The “rash” is primarily involving the patient’s trunk. Patient is otherwise healthy, and no one else at home has a similar eruption. The mother of the patient has tried some over-the-counter hydrocortisone, which has helped some with the mild itching, but the lesions persist. The pediatrician noted the linear pattern of the pinpoint papules and made the clinical diagnosis of lichen nitidus (Figure 139-1). These lines represent the Koebner phenomenon caused by scratching done by the child in areas that are reachable.
