Discoid rash occurs in 20% of patients with SLE and can result in disfiguring scars. The discoid rash can present as erythematous patches with keratotic scaling over sun-exposed areas of the skin. Follicular plugging may create scarring that may be well demonstrated in the ears. Systemic manifestations of SLE may be absent (ie, limited discoid lupus).
