Skin cells are produced and generally every 3-4 months and change, but in the case of psoriasis this process is shortened to 3-7 days. In the result of the build-up of skin cells and this leads to the formation of the characteristic changes in the body.

The cause of Psoriasis is not fully understood, it is believed that the increased cell proliferation of the skin associated with disorders of the immune system. The immune system is the natural defense of the body against infections and diseases, but in people with Psoriasis mistakenly attack the healthy cells of the skin.

Psoriasis can be inherited, and it is believed, therefore, that in this disease there is also a genetic factor. However, it is still unclear what is the role of genetics in the pathogenesis of Psoriasis.

Great smooth skin rashes to appear in some or in all of these areas. The symptoms are made worse by friction and sweating, so particular inconvenience in hot weather can provide.

Pustular Psoriasis

More than a rare type of psoriasis in which the skin appear blisters (vesicles with purulent content). Different types of pustules Psoriasis hit different parts of the body.

Generalized pulstole Psoriasis (psoriasis background Tsumbush). Pustules arise on a large surface of the skin and develop very quickly. Pus consists of white blood cells and its appearance is not always directly related with the infection. Pustules can cyclically every couple of days or weeks to appear again. At the beginning of this cycles background Tsumbush can lead to fever, chills, weight loss and chronic fatigue psoriasis.

Palmar-plantar psoriasis. Pustules appear on the palms of the hands and soles of the feet. Gradually turn into pustules are roundish brown spots with scales, which are then separated from the skin. Pustules appear again every few days or weeks.

Pustular acrodermatitis (acrobustulosis). Pustules appear on the fingers of your hands and feet. Then pustules burst, after you have red areas, which can make the liquid or covered with scales remain bright. Can lead to pain deformations of the nails.

Erythrodermic Psoriasis (erythrodermic Psoriasis)

Erythrodermic Psoriasis is a rare Form of psoriasis, which is almost the entire surface of the skin. This causes severe itching or burning. Because of the erythrodermic Psoriasis your body to lose proteins and fluid. This can lead to other complications such as infection, dehydration, heart failure, hypothermia and exhaustion.

The causes of psoriasis

Psoriasis occurs when the skin cells divide and renew themselves faster than usual. The cause of Psoriasis is not fully understood. The body produces new cells in the deepest layer of the skin. These cells are gradually moved upwards. Surround speakers, they die. This process is normally gradual and imperceptible for us. The cells of the skin are renewed every 3-4 weeks.

In people with Psoriasis this process only 3-7 days. As a result of the not yet fully grown cells can quickly collect on the surface of the skin, reducing the appearance of red, scaly and itchy keratinized lesions, covered with silvery-white scales covered. It is believed that in patients with psoriasis, the skin cells change faster because of the violation of the immune system.

The immune system is a protection of the body, which helps him to fight the infection. One of the most important types of cells used by the immune system, called T-lymphocytes.

T-lymphocytes typically move through the body to find the infection and fight with them. In people with Psoriasis, they mistakenly healthy skin grab cells. It is the immune system to produce more T-lymphocytes, and reproduce new skin cells faster than normal.

Up to the end is not clear what exactly causes a disorder of the immune system, but it may be that play a role in certain genes and environmental factors.

Psoriasis is inherited. One of the three patients with Psoriasis has a close relative with this disease. However, it is still unclear what is the role of genetics in the pathogenesis of Psoriasis. The results of the study show, for the development of Psoriasis, many genes may fulfill. Probably the people susceptible to this disease, you can make different combinations. But not the Psoriasis itself, but only the predisposition, that is, the presence of these genes mean that you will necessarily develop this disease is inherited.

  • some medicines, for example, Lithium, some antimalarial medicines, anti-inflammatory drugs, including Ibuprofen, Ace inhibitors (for the treatment ), and beta-blockers (used to treat heart failure);
  • Strep throat — in some people, especially in children and young people following a streptococcal throat infection is a Form of psoriasis called guttate Psoriasis is not developed, although, in most cases after streptococcal throat infection Psoriasis occurs;
  • other diseases of the immune system, how HIV causes the emergence or worsening of psoriasis.

Psoriasis is not contagious and can not therefore be transferred from one Person to another.

Diagnosis of psoriasis

In General, for the diagnosis of psoriasis enough external inspection of the skin.


In rare cases, the removal of a biopsy (small sample of skin), which are then sent to the laboratory to examine under the microscope.
