Erythema toxicum neonatorum (ETN) diagnosis rests on recognizing the characteristic history and physical findings in an otherwise healthy newborn.
A complete history, physical examination, and Tzanck smear are required to differentiate between benign transient pustular eruptions of the newborn and life-threatening disease.
Erythema toxicum neonatorum is a benign self-limited disorder requiring no treatment. Reassure parents regarding the benign transitory nature of the condition.
No complications of erythema toxicum neonatorum have been reported.
Most erythema toxicum neonatorum (ETN) cases resolve within 3-4 days after onset without residua. Rare recurrences are seen in a small number of patients up to age 6 weeks. In these instances, follow-up examination may be needed.
