A 5-year-old girl exhibited a bright erythematous facial rash that had been present on both cheeks for three days. The red papules coalesced to form mildly edematous, erysipelaslike, symmetric plaques that spared the perioral and nasal areas. That morning, a reticulated eruption had also developed on her trunk and extended to the buttocks and lower extremities. According to the mother, the girl had been “a little bit under the weather,” but she had neither fever nor muscle or joint aches.
