Abstract:  Infantile acne is a rare and poorly understood disorder. The objective of this study was to improve our knowledge about the epidemiology and clinical course of infantile acne, and evaluate approaches to treatment. This two-center retrospective study covered the period between 1985 and 2007. Inclusion criteria were: (i) age less than 24 months when lesions appeared; (ii) presence of both inflammatory and noninflammatory lesions; (iii) persistence of lesions for at least 2 months. The data were drawn from clinical and photographic records, followed by administration of a telephone questionnaire to parents. It was proposed that each case be reviewed on the basis of the child’s appearance and score on an acne scar clinical grading scale. Sixteen children were included. Nine had a family history of severe adolescent acne. The average duration of disease was 22 months. Two patients had been effectively treated with oral isotretinoin. More than half of the patients exhibited scars. We re-examined five children (average acne scar clinical grading scale score = 12/540). On the basis of the frequency of scarring, and the severity and average duration of lesions, the use of oral retinoids in severe infantile acne warrants evaluation.
