Full Definition
Erythema toxicum neonatorum is a common, benign condition affecting approximately 50% of full-term newborns, typically appearing within the first few days of life. The rash consists of erythematous macules, papules, and pustules that can appear anywhere on the body except the palms and soles. Despite its alarming name suggesting toxicity, the condition is completely harmless and resolves spontaneously within days to weeks without treatment. Accurate identification prevents unnecessary investigations and parental anxiety.
