[Clinical picture of erythema neonatorum].

Erythema neonatorum is the most common exanthematous eruption in neonates, which is always associated with an eosinophilic infiltration of the skin. Erythema neonatorum can be present at birth. It is of great importance in the differential diagnosis of pustular eruptions in newborns due to virus or bacteria, of miliaria pustulosa, and of incontinentia pigmenti.
