<\/span><\/h2>\nMost cases of toxic erythema in the newborn begin in the first days after birth, although the onset may be up to two weeks of age.<\/p>\n
Newborn toxic erythema is evident as various combinations of erythematous<\/span> macules<\/span> (flat red patches) papules<\/span> (small bumps) and pustules<\/span>. the eruption<\/span> typically increases and decreases over several days and is unusual for an individual injury<\/span> persist for more than a day.<\/p>\nNewborn toxic erythema often begins on the face and spreads to affect the trunk and extremities. Palms and soles are generally not affected.<\/p>\n

<\/span>How is the diagnosis of toxic erythema of the newborn made?<\/span><\/h2>\nThe diagnosis of toxic erythema of the newborn is usually made for clinical reasons. Histology<\/span> of the skin biopsy<\/span> samples taken from flat patches show a diffuse<\/span> infiltrate<\/span> of eosinophils<\/span> and neutrophils<\/span><\/span> (inflammatory<\/span> cells) at the top dermis<\/span>; of papules shows a eosinophilic<\/span> infiltration<\/span> about hair<\/span> follicle<\/span>, and of pustular<\/span> injury sample peripheral<\/span> subcorneal<\/span> pustules filled predominantly with eosinophils.<\/p>\nHow toxic newborn erythema arises is unknown. Several theories have been proposed including that it is a reaction to mechanical and thermal stimuli (heat), an "allergic" reaction, or a mild form of graft vs host<\/span> disease.<\/p>\nAlthough the toxic erythema of the newborn is benign and does not require treatment, several differential diagnoses should be considered. These include:<\/p>\n
\n- Infections (folliculitis, impetigo, listeriosis, congenital<\/span> cutaneous<\/span> candidiasis, herpes simplex, chickenpox, and cytomegalovirus)<\/li>\n
- Transient neonatal<\/span> pustular melanosis<\/li>\n
- Infantile acropustulosis<\/li>\n
- Miliaria rubra<\/li>\n
- \n
Eosinophilic pustulosis<\/span> (Childish Ofuji syndrome<\/span>)<\/li>\n- Incontinentia pigmenti<\/li>\n
- Omenn syndrome<\/li>\n
- \n
Self-healing histiocytosis<\/span>.<\/li>\n<\/ul>\nThese are generally recognized by clinical features, although in some cases the diagnosis may be aided by a Tzanck smear or skin biopsy.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"
