Erythema toxicum is a common harmless rash that appears in at
least half of all infants who are carried to term.
The condition is also sometimes called erythema toxicum
neonatorum (ETN) or toxic erythema of the newborn. The rash
usually appears within 1 to 2 days after birth, and often goes away
on its own within about a week. No one knows the cause of ETN - no
bacteria or viruses are found in the rash area. Even the pus-like
fluid that is sometimes found in the rash contains only harmless
blood cells. It is not contagious, does not require any medical
treatment, and goes away on its own.
The rash that occurs with erythema toxicum consists of tiny
bumps that are firm, yellowish or white, and surrounded by a ring
of redness. Sometimes the tiny bumps are filled with a fluid that
looks like (but isn't) pus. Sometimes there are no bumps at all
- only a splotchy redness. The rash usually appears on the
baby's face, chest, arms, and legs. It may be concentrated on
only one area of the body or it may cover much of the child's
skin. It usually does not affect the palms or soles of the
feet.
ETN is not associated with any other health problems, and a
child with the rash feels completely well. Again, because it is
harmless, ETN doesn't require medical treatment. Follow your
doctor's guidelines for your baby's normal skin care.
