Treatment of neonatal cephalic pustulosis

The neonatal or newborn period is the first 4 weeks of extrauterine life.

Patients with neonatal cephalic pustulosis (NCP) have been previously diagnosed as having neonatal acne. NCP is a pustular eruption arising on the face and/or scalp of neonates. Some believe that the two conditions are variants of the same process and actually it can be hard to distinguish between the two conditions at times. NCP lesions (comedonal lesions are not usually seen) typically appear around 2 weeks of age and usually resolve spontaneously in about 2 months. Infantile acne is much less common and usually presents later than neonatal acne/NCP at 3–6 months of age but has been reported as late as 16 months (such acne can be more severe and persistent).

It has been postulated that NCP develops in association with Malassezia species (though not all neonates with this clinical presentation have detectable Malassezia in the lesions). NCP might be related to an overgrowth of lipophilic yeasts at birth that results in an inflammatory reaction leading to monomorphic papules and pustules in predisposed neonates with more sebum production. At least some of the Malassezia-negative cases may have “genuine neonatal acne”, which is generally distinguished by the concurrent presence of comedones (when needed, patients are treated topically with benzoyl peroxide at the lowest strength possible to avoid irritation). In infants with inflammatory acne, oral erythromycin is used. In cases of erythromycin-resistant acne, oral isotretinoin can be given.

Treatment is often not required for this self-limiting disorder. If the condition persists and/or is widespread and unsightly, topical ketoconazole 2% cream for 15 days helps to shorten the duration of lesions.
