cutaneous lupus erythematosus or SCLE
involves a discoid rash that can coexist with both
discoid & systemic lupus, but may also be a 'bridge'
between Discoid LE & Systemic LE.
This type of specific lupus lesion was most recently described during the late 1970's.
This lesion is characterized as a non-scarring, erythematosus, or red, coin-shaped lesion which is very photosensitive, meaning it gets worse when exposed to UV light.
This type of lesion, occurs in lupus patients who, approximately half of the time, demonstrate features of systemic lupus erythematosus.
This form of LE comprises up to 10% of SLE cases and is usually characterised by the presence of persistent macular or slightly raised erythematous lesions on the upper trunk/torso and arms.
These skin lesions may also occur in people who only have clinical evidence of skin disease (discoid lupus), and do not show any symptoms of systemic lupus.
The subacute cutaneous lupus lesion can sometimes mimic the lesions of psoriasis or they can appear as non-scarring, coin-shaped lesions much like hives.
These lesions can also occur on the face in a butterfly distribution (malar), and similar to rosacea, as well as covering large areas of the body.
Unlike the discoid lupus lesions, these lesions do not produce permanent scarring, but can be of major cosmetic significance to the patient involved.
