• Subacute cutaneous lupus erythematosus • Psoriasis • Lichen planus • Tinea faciei • Granuloma annulare • Sarcoidosis • Morphea • Actinic keratosis
• Most common form of chronic cutaneous lupus — only ~5-10% progress to SLE • Classic triad: erythema, scale with follicular plugging, and atrophic scarring • Carpet tack sign: adherent scale with follicular plugging seen on underside of removed scale • Scarring alopecia is a significant complication — early treatment prevents permanent hair loss • DIF (lupus band test): granular deposits of IgG, IgM, IgA, and C3 at DEJ in lesional skin • Dyspigmentation (central hypopigmentation with peripheral hyperpigmentation) especially prominent in darker skin • More common in African Americans and women
