Discoid erythema

Discoid lupus erythematosus (DLE) is a chronic recurrent disease that mainly invades the skin. It is characterized by well-defined red patches (erythema), hair follicle embolism, scales, telangiectasia, and skin atrophy. The cause is unclear. More common in women, the highest incidence around 30 years old. The disease can be divided into two types: ① localized skin damage is limited to the skin above the neck; ② disseminated skin lesions affect the skin of a wide range of parts of the body. Some authors believe that disseminated forms can easily turn into systemic lupus erythematosus.
