Psoriasis (psoriasis) or scaly lichen is a dermatosis of non-infectious origin. The true causes of the disease are not clear. Currently, the provoking factor is considered to be a violation of autoimmune processes.
Accompanied by pain and severe itching, causing not only physical suffering but also psychological discomfort. The root cause of plantar psoriasis can be a common skin injury.
Psoriatic rashes can have a strict localization and always appear in the same places on the body. The clinical course of this form of the disease is usually milder. However, it is characterized by frequent and persistent exacerbations.
Psoriasis is a very common disease. It can affect almost any part of the skin and body. Thus, there are lesions of the nails, fingers, face, scalp, as well as bones and joints. But psoriasis on the elbows is still most often diagnosed.
In the classic form of psoriasis, the lesions are usually bilateral and symmetrical, which is why it is important to perform a complete skin examination – even if the patient has not noticed these lesions.
Most patients with vulgar psoriasis have characteristic rashes not only on the skin of the elbows and knees, but also all over the body, including the head. And skin lesions on the head are often defined as seborrheic psoriasis.
