Acne neonatorum/acne infantum

Acne is generally considered to be a disease of adolescence. However 20% of newborns have acne neonatorum, which may to be overlooked because it is usually mild and transient. Acne can also be seen in infants and children, where the skin lesions are normally more severe. We describe a case of a ten-month-old boy with severe acne without other underlying diseases. Treatment with systemic erythromycin and local application with isotretinoin gel was moderately succesful, but the eruption cleared when treated with isotretinoin 0.5 mg/kg.
