Discoid lupus erythematosus (DLE) is an inflammatory scarring alopecia. It is an autoimmune condition and a type of chronic skin lupus.
It presents as a sharply-demarcated red, scaly plaque with a central depressed scar, central skin lightening, follicle scale plug, and a surrounding dark patch.
It occurs 4-5 times more common in black women compared to white women. Systemic lupus erythematosus (SLE) may develop in 5-25% of people with DLE.
It may be associated with other autoimmune conditions and increased risk for squamous cell carcinoma.
Management includes the use of sun protection, anti-inflammatory medications (i.e. steroids (topical/ oral/ injection), tacrolimus, methotrexate, etc.)
