erythema neonatorum

a common skin condition of neonates characterized by a pink papular rash frequently superimposed with vesicles or pustules. The rash appears within 24 to 48 hours after birth and disappears spontaneously after several days. A smear of the papules that reveals the presence of eosinophils rather than neutrophils differentiates the condition from neonatal pustular melanosis. Also called toxic erythema of the newborn.
