【 摘 要 】

Follicular red dots have been described as a trichoscopic feature of active discoid lupus erythematosus of the scalp and its presence associated with a better prognosis. We report five patients with pigmentary disorders in whom follicular red dots were detected during scalp examination. We suggest that this pattern is probably related to the rich vasculature that naturally envelops the normal hair follicle. The possible implications of such proposition in cases of discoid lupus erythematosus and other scalp disorders are also discussed.
