Erythema toxicum neonatorum (also known as erythema toxicum urticaria neonatorum and toxic erythema of the newborn) is a common rash in neonates. It appears in up to half of newborns carried to term usually between day 2–5 after birth; it does not occur outside the neonatal period. Erythema toxicum is characterized by blotchy red spots on the skin with overlying white or yellow papules or pustules. These lesions may be few or numerous.
