Last reviewed: July 30, 2014.

Erythema toxicum is a common skin condition seen in newborns.

Causes

Erythema toxicum may appear in approximately half of all normal newborn infants. The condition may appear in the first few hours of life, or it can appear after the first day. The condition can last for several days.

Although erythema toxicum is harmless, it can be of great concern to the new parent. Its cause is unknown.

Symptoms

The main symptom is a rash of small, yellow-to-white-colored bumps (papules) surrounded by red skin. There may be a few or several papules. They are usually on the face and in the middle of the body. They can also be seen on the upper arms and thighs.

The rash can change rapidly, appearing and disappearing in different areas over hours to days.

Exams and Tests

Your baby's health care provider can often make a diagnosis during a routine exam after birth. Testing is usually not needed.

Treatment

The large red splotches usually disappear without any treatment or changes in skin care.

Outlook (Prognosis)

The rash usually clears within 2 weeks. It is usually completely gone by age 4 months.

When to Contact a Medical Professional

Discuss the condition with your baby's health care provider during a routine examination if you are concerned.
