A HEALTHY 8-year-old girl presented with a 6-week history of an acute, generalized skin eruption. Her palms and soles had become thickened and scaly over a 3-year period prior to eruption of the rash. Approximately 1 week before the eruption, she had mild pharyngitis. Over 1 to 2 days, erythema and scaling developed on her elbows, knees, scalp, and face. Over the following 1 to 2 weeks, the eruption spread over her upper and lower extremities and lastly over her trunk. The rash became increasingly hyperkeratotic and orangish-red in hue, and it covered 80% of her total body surface area (Figure 1 through Figure 4).
