Picture of Transient Neonatal Pustular Melanosis

Transient neonatal pustular melanosis. This is a benign neonatal dermatosis that is most common among African- American infants. The original lesion is a vesiculopustule, which may be present at birth. This small blister quickly ruptures and leaves a typical collarette of superficial scale processes. Tzanck smear of a pustule of erythema toxicum neonatorum will reveal numerous eosinophils but no multinucleated giant cells or bacteria. Occasionally, peripheral eosinophilia is also present. The cause of this condition is not known, and it resolves spontaneously within 10 days. No treatment is required.
