[Erythema toxicum neonatorum].
(ETN) is a benign, self limited, asymptomatic skin condition, that only occurs during the neonatal period. This clinical entity is caractherized by small, sterile, erythematous papules, vesicles, and occasionally pustules, appearing on the trunk, extremities, and the face. The lesions are transitory, appear after 1-2 day of life, and regres after 5-14 days. ETN occurs in 30-50% of full-term infants, and just in 5% of preterm infants, with no significant differences based on race or sex. The ethiology or pathophysiology of ETN are uncertain, but the presence of the eosinophilic infiltrate in the lesions of erythema suggests an allergic ethiology, even no allergens have been identified. The treatment is not required, and the prognosis is excellent with spontaneous resolution.
