History

Erythema toxicum neonatorum (ETN) typically presents in term neonates aged 3 days to 2 weeks. Although erythema toxicum neonatorum can occur in the first 48 hours, approximately 90% of cases occur after 48 hours. The eruption is characteristically evanescent, with lesions appearing and disappearing within minutes to hours.

Physical

Asymptomatic small papules, vesicles, and, occasionally, pustules are present on the skin. These are usually seen on dependent areas, generally starting on the trunk. They then tend to spread centripetally. The lesions are surrounded by a distinctive blotchy erythematous halo on the trunk, extremities, and face.
