It is believed that this genetically determined dermatological pathology has an autoimmune or immune-mediated nature. That is, it is not an infection, but a kind of dermatosis, and it is impossible to become infected with psoriasis.
This non-contagious chronic dermatosis during periods of exacerbation causes a lot of physical and psychological discomfort; itchy rashes (often over a large area of the body) do not give rest either day or night.
The way psoriasis manifests itself depends on the stage of the disease. In clinical dermatology, there are three main stages of psoriasis: progressive, stationary and regressive.
The most common type 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 aggravating course.
A pathology such as scalp psoriasis (especially scalp psoriasis) can be attributed to the group of diseases involving autoimmune pathogenetic mechanisms. It increasingly affects not only elderly patients, but also young people.
Psoriasis is a well-known skin disease that cannot 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 without success.
Skin psoriasis is a fairly well-known and widespread disease that is accompanied by a disruption of normal cell division. However, not many people know that there is another similar pathology that affects the nail plate - nail psoriasis.
Psoriasis can be localized on different parts of the body, and hands are no exception. The disease does not pose a threat to life, but it greatly affects the quality of life.
Parapsoriasis was first described in 1902 by Brocq. He combined three dermatoses into one group that had some common features: chronicity of the course, superficial nature of the spotty-scaly rash, absence of any subjective sensations and general phenomena, resistance to therapy.
