It is believed that this genetically determined dermatological pathology has an autoimmune or immuno-mediated nature. That is, it is not an infection, but a kind of dermatosis, and you can not get psoriasis.
This non-contagious chronic dermatosis during the exacerbation brings a lot of physical and psychological discomfort, itchy rashes (often on a large surface of the body) do not give rest day or night.
The way psoriasis manifests itself depends on the stage of the development of the disease. In clinical dermatology, there are three main stages of psoriasis: progressive, stationary and regressive.
The most common form of psoriasis is psoriasis on the head - this is an extremely unpleasant pathology, to which the term "scaly lichen" is also applied. The disease has a chronic, periodically exacerbating, course.
To a group of diseases involving autoimmune pathogenetic mechanisms, one can include a pathology such as psoriasis of the head (especially its hairy part). It increasingly affects not only patients aged, but also young people.
Psoriasis is a known skin disease that can not be cured. For many decades scientists have been trying to explain the causes and determine an effective remedy for the treatment of this disease, but, unfortunately, so far, unsuccessfully.
Psoriasis of the skin - this is a fairly well-known and common disease, which is accompanied by a violation of normal cell division. However, not many know that there is another similar pathology affecting the nail plate - this is psoriasis of the nails.
Psoriasis can be localized on different parts of the body, and the hands are no exception. Threats to life the disease does not carry, but greatly affects the quality of life.
Parapsoriasis was first described in 1902 by Brocq. He combined three dermatoses into one group, having some common features: chronicity of the course, surface character of spotted scaly rash, absence of any subjective sensations and general phenomena, resistance to therapy.
