Scars and atrophy form in the center of the lesions. The disease is chronic, with exacerbations and remissions.

Lupus erythematosus discoid

**Discoid lupus erythematosus** is a chronic inflammatory skin disease characterized by damage to the superficial layers and the presence of characteristic scars in the affected areas. Mostly women are affected.

The disease begins suddenly, several weeks or months after exposure to provoking factors such as skin trauma, infectious inflammation of the skin, ultraviolet radiation, stress. Erythema (redness), tingling, itching, burning and dry skin occur. The affected area gradually increases, forming a papule and then a pustule with the formation of transparent, sticky, drying yellowish crusts. In the progressive stage of the disease, edema develops and papillary growth appears, but, unlike other types of pityriasis rosea, there are no disturbances in the general condition. Typically, skin atrophy with pigmentation develops in the affected area. Sometimes, bluish-red small bumps of regular shape may appear, which is characteristic of the psoriasis-like form of discoid lupus erythematosus. In this case, patients experience an increase in temperature, deterioration in health, weakness and increased fatigue, pain in muscles and joints. Signs of the disease are often found in peripheral lymph nodes. In the stationary stage of the disease, sebaceous plugs form, the skin becomes brownish-red in color and peels off. Scars may have a bluish-purple, sometimes irregular appearance with atrophy of the skin. There is no infiltration in such patients. There are few cases of complete recovery. Mortality is high, does not exceed 30%.

Differential diagnosis includes pityriasis rosea, deep staphyloderma, skin tuberculosis, and parasitic mycoses. The disappearance of rashes during treatment with glucocorticosteroids indicates damage to the skin by pathogens of neoplastic processes (lymphogranulomatosis, vitiligo
