Alopecia areata: Dermatoscopic differences between pediatric and adult patients

The study compared dermatoscopic features of alopecia areata in 96 children and 171 adults. It found that pediatric alopecia areata was more common in females, while adult males were more likely to have the disease. Multiple patches were common in both groups, with yellow dots being the most frequent sign in children and short vellus hairs in adults. Nail involvement was linked to severe disease in both groups. The study highlights differences in dermatoscopic signs and their association with disease severity between children and adults.
