Abstract
The most characteristic trichoscopic features of active discoid lupus erythematosus are large yellow dots (keratotic plugs), thick arborizing vessels, scattered dark-brown discoloration, red dots, and blue-gray dots. Longstanding, inactive disease is characterized by the presence of structureless milky red or white areas and a lack of follicular openings. Thick arborizing vessels also may be present.
