Discoid lupus erythematosus and systemic lupus erythematosus are clinically distinct entities. Discoid lupus is a chronic, relatively common dermatitis that is more common in women than in men. It presents as erythematous plaques that vary from an atrophic to a hyperkeratotic appearance in the region of the face, scalp, neck, extremities, and trunk. [31] It is usually exacerbated by sunlight. [32]
