The cells of the skin are generally produced and exchanged every 3 or 4 months, but when the psoriasis this process is shortened to 3-7 days. As a consequence, occurs the accumulation of skin cells, which leads to the appearance of characteristics of changes in the body.

The causes of psoriasis are not yet clear, it is believed that an increase of the reproduction of skin cells is related to immune system disorders. The immune system is a natural protection of the body against infections and disease, but people with psoriasis it of error attacks the healthy cells of the skin.

Psoriasis can be transmitted by inheritance, and, therefore, it is believed that this disease there is a genetic factor. However, it is still not clear what is the role of genetics in the onset of psoriasis.

Many people, the symptoms of psoriasis appear or are enlarged after an event, which is called the trigger. Possible triggers when psoriasis include skin injuries, infections, diseases of the throat and the reception of a particular medicine.

At the beginning of these cycles psoriasis background Tsumbush can cause fever, chills, weight loss, and chronic fatigue.

Palmar-plantar psoriasis. Pustules appear on the palms of the hands and soles of the feet. Gradually turn into pustules rounded brown plate with scales, which is then separated from the skin. The pustules may reappear every few days or weeks.

Pustular acrodermatitis (acrobustulosis). Pustules appear on the fingers of your hands and feet. Then, the pustules burst, then they become bright red area, that may secrete liquid or accumulate the time. It can cause painful deformation of the nail.

Erythrodermic psoriasis (psoriatic erythroderma)

Erythrodermic psoriasis — a rare form of psoriasis, affects almost the entire surface of the skin. This causes a strong itching or burning sensation. Because of erythrodermic psoriasis your body can lose proteins and liquid. This can lead to the appearance of other complications, such as infection, dehydration, heart failure, hypothermia and exhaustion.

The causes of psoriasis

Psoriasis occurs when the skin cells are divided and updated more quickly than usual. The causes of psoriasis are not yet clear. The body produces new cells in the heart the deep layer of the skin. These cells move gradually to the top. Came out to the surface, they die. This normal process occurs more slowly and invisibly to us. The skin cells are updated once every 3-4 weeks.

In people with psoriasis, this process has the duration of only 3 to 7 days. The result are not yet fully mature cells rapidly accumulate on the surface of the skin, causing the appearance of red, peeling and Horny eruptions, covered with scaly white-silvery. It is believed that the patients of psoriasis, the skin cells are changing more rapidly due to diseases of the immune system.

The immune system is the body's defense, which helps fight infection. One of the main types of cells, which uses the immune system, called lymphocytes.

The t lymphocytes, normally, are moved through the body, are infection and fight with them. People with psoriasis they of error attack the healthy cells of the skin. This causes the immune system to produce more T lymphocytes, as well as reproduce new skin cells faster than normal.

It is not clear what exactly causes the violation of the immune system, although it may be that some role to play some genes and environmental factors.

Psoriasis is inherited. One of the three psoriasis patients have a close relative with the disease. However, it is still not clear what is the role of genetics in the onset of psoriasis. The results of the study indicate that, for the development of psoriasis can find several genes. Probably, make the person more susceptible to this disease can their various combinations. However, it is inherited is not the own psoriasis, but only a predisposition to it, that is, the presence of these genes does not mean that you necessarily will develop this disease.

  • some medicines, such as, for example, lithium, some medication, anti-malaria, anti-inflammatory drugs, including ibuprofen, ACE inhibitors (for treatment ) and beta-blockers (for the treatment of congestive heart failure);
  • infection of the throat — in some people, especially children and young adults after streptococcal infections of the throat develops a form of psoriasis is called guttate psoriasis, although in the majority of cases, after streptococcal infections of the throat psoriasis does not occur;
  • other diseases of the immune system, such as HIV, which cause the appearance or worsening of psoriasis.

Psoriasis is not contagious and, therefore, cannot be transmitted from one person to another.

The diagnosis of psoriasis

As a general rule, for the diagnosis of psoriasis is enough to visual inspection of the skin.


In more rare cases require taking a biopsy (a small sample of skin), which is then sent to a laboratory for study under the microscope.
