REPORT OF A CASE
A 6-week-old Hispanic girl presented to the pediatric dermatology clinic with a 4-week history of a vesiculopapular eruption on the hands, feet, chest, and buttocks. The patient was born by cesarean section at 40 weeks' gestation to a 36-year-old mother. The baby's delivery was complicated by prolonged rupture of membranes, requiring intravenous administration of ampicillin and gentamicin. Bacterial cultures of the baby's blood and spinal fluid yielded no organisms.The eruption was not present at birth but was first noted by the referring pediatrician on the child's hands, feet, and buttocks around 2 weeks of life. The patient was not receiving medications at the time of onset of the eruption.On initial physical examination, the girl had multiple discrete, well-circumscribed 1-mm to 3-mm vesicles and pink papules on the palms, soles, chest, and buttocks (Figs 1 through 3). Two weeks later, discrete, flat-topped papules were present
