A 7-month-old boy was brought by his
parents for a facial eruption that had been present for last
two months. There was no history of any topical or systemic
medications. The 26-year-old mother had a history of acne
vulgaris during adolescence. Examination revealed multiple
closed and open comedones, inflammatory papules, and a few
pustules distributed on the cheeks and nose (Fig.
1). There were no other mucocutaneous abnormalities;
systemic examination was normal. A diagnosis of infantile
acne was made; lesion improved gradually on once-nightly
application of benzoyl peroxide (2.5%).

comedones in infantile acne.
Although acne is a disorder of
adolescence, newborns and infants may rarely develop it.
Neonatal and infantile acne is predominantly comedonal and
usually limited to the face. Infantile acne needs to be
differentiated from staphylococcal folliculitis (superficial
postules with no comedones) and acneform eruption (monomorphous
inflammatory papules often with a history of topical steroid
abuse). Regular cleansing with a mild soap, and avoidance of
application of oil or greasy substances is advised in mild
disease. Moderately severe lesions may be treated with
topical benzoyl peroxide (2.5%), clindamycin or tretinoin.
