ICD-11 KC21.1 — Neonatal toxic erythema

Neonatal toxic erythema is a common rash in neonates, appearing in up to half of newborns carried to term, usually between day 2-5 after birth; it does not occur outside the neonatal period and typically resolves within first two weeks of life. It is characterised by blotchy erythema with crops of evanescent small white or yellow papules or pustules. It is a benign condition and is thought to cause no discomfort to the baby.
