11.
Antinuclear antibody
most upregulated gene pathway identified in microarray studies in SLE patients
type 1 IFN
Although perivascular nail fold erythema and telangiectasia can occur, they are considerably more common and occur in more exaggerated forms in dermatomyositis and systemic sclerosis
ACUTE CUTANEOUS LUPUS ERYTHEMATOSUS
typically precipitated or exacerbated by exposure to UV light.
This form of CLE can be quite ephemeral, lasting only hours, days, or weeks
ACLE
initially presents as erythematous macules and/or papules that evolve into hyperkeratotic papulosquamous or annular/polycyclic plaques
SCLE
SCLE lesions tend to be less transient than ACLE lesions and heal with more pigmentary change. They are also less edematous and more hyperkeratotic than ACLE lesions
most common form of CCLE
Classic DLE
nonscarring alopecia that patients with SLE often develop during periods of systemic disease activity
lupus hair
hyperkeratosis, epidermal atrophy, vacuolar basal cell degeneration, dermal–epidermal junction basement membrane thickening, dermal edema, dermal mucin deposition, and mononuclear cell infiltration of the dermal–epidermal junction and dermis, focused in a perivascular and periappendageal distribution.
