Leaven red flat

Lishay red flat - a disease that affects the skin, mucous membranes, less often the nails.

Etiology, pathogenesis are not established. The most common theories of infectious (possibly, viral) and neurogenic origin of the disease. Mostly adults are ill.

The clinical picture is characterized by monomorphic small polygonal papules of reddish purple color with a flat shiny surface and an umbilical impression in the center. Papules are usually located in isolation, mainly on the flex surfaces of the forearm, abdomen, lower back and are accompanied by severe itching. Papules can merge with the formation of small plaques (such as "cobblestone pavement"). On the surface of the papules a whitish net-like grid pattern of the Vicum is revealed, which is especially visible when the elements are moistened with water or lubricated with vegetable oil. Sometimes they form ring-shaped figures. At the site of absorbable papules, persistent pigmentation often remains. The defeat of the mucous membranes (oral cavity, genital organs) can be both isolated and combined with skin lesions. On the inner surface of the cheeks, the red border of the lips, the lateral surfaces of the tongue, on the vulva or the glans penis there are small whitish shiny papules forming a "fern pattern" or a mesh.

In addition to the typical, other varieties of red lichen planus on the mucous membranes are possible: exudative-hyperemic, characterized by the location of papules on a puffy hyperemic (exudative) background; Erosive-ulcerative, accompanied by the formation of erosions or small ulcers surrounded by papules (the latter variety often develops in patients with diabetes and hypertension). The disease is characterized by a chronic recurrent course.

The diagnosis is based on the characteristic type of papules, the presence of a Wickema mesh, typical localization, itching.

Treatment. In the acute period, if there are chronic foci of infection in the patient, broad-spectrum antibiotics, calcium preparations, antihistamines, sedative therapy, anelecroson (can be combined with adrenal diathermy), diadynamic currents, paravertebral, vitamins C, A, Groups B are shown. Externally, agitated suspension (Zinc oxide, talc, 10 g starch, glycerin - 20 ml, distilled water - up to 100 ml), corticosteroid ointments (preferably a bandage dressing).
