Acne occurs more frequently in newborns and infants than one would gather from written accounts. Acne neonatorum tends to be overlooked because it is usually minor and transient. In contrast, acne infantum, which generally does not make its appearance until after 3 months of life, is more serious. Even acne conglobata may develop in infants. There are many other types of acne in childhood reflecting different pathogenetic mechanisms; included in this group are acne venenata infantum, steroid acne, hormonal disturbances, and toxic reactions.Acne is generally considered to be a disease of adolescence, often extending into adult life-However, it can be seen in small children, infants, and even newborns-In our experience childhood acne is more common than the sparse literature would suggest. Many different types can be identified; boys are far more likely to be affected than girls (Table 1)-The cutaneous changes are usually confined to the face and consist of comedones, papules, and pustules. Rarely, deeper nodules and scarring may be seen.
