An 8-year-old boy whose family had recently immigrated from Southeast Asia was brought to the emergency department (ED) with a well-demarcated, pruritic rash that had appeared on his face 6 weeks earlier. At that time, the patient's primary care physician had diagnosed Fifth disease. As the rash spread to the child's arms and back, atopic dermatitis was considered. The week before presentation in the ED, the rash had become more inflamed and pruritic and was accompanied by fevers.
