• Transient neonatal pustular melanosis was diagnosed in 13 of 5,267 infants examined over a period of 17 months, representing an incidence of 0.24%. The skin eruption was always present at birth and developed within a few days from pustules to a round, brownish crust, which could easily be detached. Histological examination of two biopsy specimens obtained at the age of 4 days showed hyperkeratosis with keratotic plugs and a crust of leukocytes, but no increased melanin.
