Synonyms: erythema neonatorum allergicum; toxic erythema of the newborn
Erythema toxicum neonatorum (ETN) only occurs in the newborn, usually presenting within the first week of life. It has the appearance of small, erythematous papules and vesicles. Occasionally pustules also occur. The lesions are often surrounded by areas of diffuse blotchy erythema, giving the appearance of a distinct halo.
