A 1420-g female infant was born prematurely at 33 weeks 4 days' gestation to an otherwise healthy 39-year-old mother. The pregnancy was complicated by maternal hypertension and oligohydramnios. The baby presented with physiologic jaundice and was treated with visible light phototherapy. While unconjugated hyperbilirubinemia improved, extensive areas of confluent, nonpalpable purpura developed (Figure 1and Figure 2).
