definitionBenign subtype of lupus erythematosus involving the skin, particularly the face. 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. |
