AbstractA sterile pustular skin eruption was observed in 17 of 3,541 newborn infants examined over a period of 30 months. The skin eruption was always present at birth and fulfilled the clinical criteria of transient neonatal pustular melanosis (TNPM). However, some days after birth, all of them but 1 developed skin lesions typical of erythema toxicum neonatorum (ETN). Histological examination of 11 biopsies obtained at the age of 1 day showed intracorneal neutrophilic pustules in 4 and subcorneal intraepidermic eosinophilic pustules in 7. On the basis of our findings and a literature review we consider that a clear-cut differentiation between TNPM and ETN is not always possible. We propose the name sterile transient neonatal pustulosis to unify these conditions.
