A 25-year-old G2P1 mother gave birth to a boy at 40 and 6/7 weeks by vaginal delivery. Labor was induced because of oligohydramnios complicated by chorioamnionitis. The mother was treated with vancomycin and gentamicin. Prenatal lab work and delivery were otherwise unremarkable.
The delivering physician (CG) noted that the neonate had numerous brown, red, and black plaques distributed over his abdomen, lower back, groin, and thighs (FIGURE). Some plaques were hypertrichotic and other areas, apart from the plaques, were thinly desquamated. Apgar scores were 8 and 9 and the remainder of the exam, including the neurologic exam, was normal. The Dermatology Service (JK) was consulted.
