Acne neonatorum in the eastern Saudi Arabia.

ABSTRACT

BACKGROUND: Acne neonatorum (AN) is characterized by a facial eruption of inflammatory and noninflammatory acne lesions in a neonate. Hyperactivity of sebaceous glands, stimulated by neonatal androgens, is implicated in its pathogenesis. AIM: To elucidate the clinical profile of AN in eastern Saudi Arabia. METHODS: All patients diagnosed with AN in King Fahd Hospital of the University in Khobar, Saudi Arabia, during the year 2005 were evaluated clinically. RESULTS: AN was diagnosed in 26 patients (male/female ratio 11). The lesions included mainly facial comedones (30.8%); papules and pustules (15.3% each); and combination of papules, pustules, and cysts (53.4%). CONCLUSION: All patients recovered spontaneously. In 50% of the cases, one of the parents reported having had acne vulgaris during adolescence. Hereditary factors seem to play a significant role in our series.
