Erythema toxicum (or toxic erythema) is a common rash in neonates.[1]:139[2] It appears in up to half of newborns carried to term, usually between day 2-5 after birth.
Contents |
Presentation
The rash is composed of small papular 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. The rash will generally disappear spontaneously in about 2 weeks.
