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.

Erythema neonatorum was found in 59 patients and in only 3 of them it persisted beyond 7 days.
Lanugo hair, sebaceous hyperplasia, erythema neonatorum, cutis marmorata and iatrogenic bruises were frequently seen in preterm neonates, whereas miniature puberty, physiological desquamation, milia, neonatal acne, Mongolian spot, miliaria and intertrigo were more frequently seen in term neonates.
Physiological desquamation, iatrogenic bruises and ecchymosis were more common in male neonates, whereas sebaceous hyperplasia, erythema neonatorum and cutis marmorata were more common in female neonates.
Other findings like physiological desquamation, Mongolian spots, miliaria, cutis marmorata and erythema neonatorum did not show statistically significant difference.
