An 8-month-old African American girl presented with a 2-week history of an erythematous papular eruption that had started on the left upper aspect of her arm, proximal to the axilla, and had spread peripherally. Five days after the lesions appeared, she developed a temperature of 39°C that lasted for 72 hours. On her first visit to the dermatology department, 0.025% triamcinolone ointment was prescribed. She returned in 5 days with more extensive lesions despite topical steroid use.
