Trichoscopic Differentiation in Alopecia: A Retrospective Case Series Comparing Lichen Planopilaris, Discoid Lupus Erythematosus, and Alopecia Areata
ABSTRACT
This single-center retrospective case series included 28 patients with alopecia (LPP, n =7; DLE, n =7; AA, =14). Trichoscopic markers were systematically compared across groups. Exclamation-mark hairs and yellow dots were characteristic of AA, whereas follicular ostia loss and white scarring were confined to LPP/DLE, providing a simple and practical distinction between nonscarring and scarring alopecias in routine practice.
