A 4-year-old black boy with a long-standing history of eczema had a worsening rash and complained of increased itching and cutaneous pain. Two days before presentation, he had begun to run a fever. His current temperature was 101.8°F, and he had eczematous lichenified dermatitis on his legs, arms, torso, and face.
