This is an autoimmune disease affecting predominantly the skin. It presents as bald, scaly red patches on the scalp. The skin is thinned out and prominent capillaries may be seen on the patches. Hair loss in these scarred patches are obvious and is often permanent. The skin lesion is painless and not itchy. Other areas of the skin e.g. the face and ears are often affected. Such skin lesions are often sun-sensitive. Laboratory tests including a skin biopsy are required to confirm the diagnosis.

DLE should be treated immediately to prevent progressive scarring and balding of the scalp. There are effective treatments for the disease but scarred lesions are usually not responsive to treatment. Occasionally, the internal organs e.g. the lungs, kidneys and heart may be affected by the disease leading to a condition called systemic lupus erythematosus. Hence, regular check-up by your doctor is necessary if you suffer from DLE.
