Erythema toxicum may appear in 50 percent or more of all normal newborn infants. It usually appears in term infants between the ages of three days and two weeks. Its cause is unknown. The condition may be present in the first few hours of life, generally appears after the first day, and may last for several days. Although the condition is harmless, it can be of great concern to the new parent.

There may be a few or many whitish papules and the associated erythema (redness) may be splotchy and extensive. The lesions are usually on the face and trunk, but they can also appear on other areas of the body including the upper arms, and thighs. Individual lesions are often transient, appearing in one area for several hours and then appearing in a different location.
