Signs and Symptoms
Erythema toxicum appears as small (1–3 mm), firm, yellow or white raised bumps filled with pus on top of a red area of skin. There may be a few to many lesions, and they may be found on any area of the body, with the exception of palms and soles. Erythema toxicum often begins on the face and spreads, and it may be clustered in areas where there is pressure on the skin. Although it most frequently appears during the first 3–4 days of life, erythema toxicum can be seen at birth and may not be present until 10 days of life. New lesions may appear as older ones resolve.
