Further Outpatient Care
Erythema toxicum neonatorum (ETN) is a self-limited condition that typically resolves within 2 weeks after birth. If the condition persists or does not follow the usual course, prompt consultation with a specialist is advised.
Complications
No complications or sequelae are noted with this eruption. Because of the presence of eosinophils within the lesions, investigators suspect an association with atopic disease; however, studies examining these potential links to atopy have not demonstrated any clear association.
Prognosis
The prognosis is excellent. The lesions typically resolve within 2 weeks, and no cutaneous or systemic sequelae are generally observed.
Patient Education
Parents with older children often are not concerned by the appearance of erythema toxicum neonatorum, but first-time parents should be informed in the perinatal period that an evanescent rash is likely to appear within the first 2 weeks of life. They should be reassured regarding the benign, self-limited, asymptomatic nature of this and other eruptions.[12]
Review the clinical features with parents before they go home. If any concerns arise about an atypical rash, they should be comfortable contacting their primary care physician to discuss the issues. Before discharge, appropriately screen neonates who have risk factors for sepsis or neonatal herpes simplex virus infection.
