Characteristic trichoscopic findings of discoid lupus erythematosus include large yellow dots, red dots and large yellow dots with radial, thin arborizing vessels emerging from the dot (also known as “red spider in yellow dot”). Other typical trichoscopic features of the disease are thick arborizing vessels, scattered dark-brown discoloration and blue-grey dots arranged in a “speckled” pattern (2).
The active (early) discoid lupus erythematosus is characterized by presence of thick arborizing vessels, large yellow dots, fine interfollicular scaling, red and blue-grey dots and brown discoloration (4, 5) (3).In inactive (end-stage) lesions mainly white and milky-red areas with lack of follicular openings, arborizing vessels and yellow dots containing thin spider vessels are observed (4).
