According to the literature, about 3% of the world's population suffers from psoriasis; the highest prevalence is observed in the countries of Western Europe and Scandinavia, while this disease is less common among representatives of the Mongoloid and Negroid races. In different countries, the proportion of psoriasis is from 10 to 40% in the total structure of skin diseases. This pathological process has a multifactorial nature; it is based on hyperproliferation of keratinocytes with impaired differentiation, which clinically manifests itself in the form of damage to the skin, nails and joints. Psoriasis is one of the most common dermatoses; men and women suffer from it equally often. The triggering factor for the development of psoriasis can be a psychoemotional stressful situation, as well as the impact of other environmental factors, including hypothermia, trauma, infections, and taking certain medications. As a result of exposure to provoking endogenous and exogenous factors, autoimmune mechanisms, which are based on increased activity of T cells, are triggered. About 70% of psoriasis patients have mild to moderate severity of the disease. Despite the wide range of drugs used to treat psoriasis, they do not demonstrate high efficiency, and the prevalence of this pathology is growing every year. The existing methods of treatment help to cope with exacerbations and relieve inflammation, however, it is impossible to completely cure this disease, and the risk of relapse always remains. One of the tasks of doctors involved in the treatment of psoriasis is not only to reduce the severity of symptoms, but also to teach a patient suffering from psoriasis to live a full life and not depend to a large extent on the manifestations of the disease and the opinions of others.
