Discoid lupus erythematosus Ear
The lesions typically present as well-circumscribed, erythematous plaques with telangiectasia and scales and atrophy in long-standing disease.
DLE is a Benign subtype of lupus erythematosus involving the skin, particularly the face and can involve pinna as in the above case. It is characterized by various-sized, erythematous, well-defined, scaly patches, which tend to heal with atrophy, scarring and pigmentary changes. The onset of the lesions may be precipitated by trauma, mental stress, sunburn and exposure to cold. Visceral involvement does not occur, but a small percentage of patients with DLE may later develop a systemic lupus erythematosus. Haematological and serological changes in about half the patients suggest an autoimmune aetiology.
Rx-corticosteroids are prescribed to decrease the immune system response. Topical creams that are applied to the rash areas are effective in reducing their spread and severity. A cortisone injection directly into lesions is another alternative. Antimalarial medications are also effective treatments for discoid lupus.
