MeshID =Erythema toxicum (or toxic erythema) is a common rash ininfants .cite journal |author=Berg FJ, Solomon LM |title=Erythema neonatorum toxicum |journal=Arch. Dis. Child. |volume=62 |issue=4 |pages=327–8 |year=1987 |month=April |pmid=3592724 |pmc=1778345 |doi= |url=] It appears in up to half of newborns carried to term, usually between day 2-5 after birth.Presentation
The rash is composed of small pustular lesions, each on a separate reddened base.
Diagnosis
At times the appearance can raise concern that the rash could be due to
herpes simplex , however the latter generally has a more clustered and vesicular appearance.In uncertain cases, a scraping of a lesion can be done and the fluid examined under the microscope. Herpes lesions will have a positive
direct fluorescent antibody test. The fluid from erythema toxicum lesions will show many eosinophils.Causes
The cause of erythema toxicum is unknown, but it is thought to be a benign condition that causes no discomfort to the infant and the rash will generally disappear spontaneously in about 2 weeks.
