With the passage of this inflammatory process, the skin cells are divided much faster than with their normal development. Under normal conditions, the formation of cells takes from 21 to 30 days, and in psoriasis, the full growth phase passes in 7 days.
Answering the question about how psoriasis starts, it should be noted that most experts believe that Such an ailment as psoriasis refers to multifactor diseases and is transmitted mainly by inheritance.
However, some experts believe that the development of this disease can be influenced by such additional reasons as:

The most common form of psoriasis is usually considered vulgar. This form of the disease is diagnosed in 90% of patients. Even without any effort, the upper layer of the epidermis can be removed, exposing the inflamed skin of red color. Given that with psoriasis, the vessels are very close to the surface of the skin, plaques can often bleed.

It is the psoriatic triad in most cases that makes it possible to distinguish the disease from others.
Symptoms of the disease
Like any other disease in psoriasis, there are characteristic stages of development, depending on which the disease manifests its main symptoms.
This is due to the fact that in the summer because of the significant effect of ultraviolet skin condition is significantly improved.
The disease passes through 3 main stages of development:
At this stage, an active lesion of the skin and the involvement of new skin in the process are observed. This stage is characterized by a very strong manifestation of such symptoms as scaling and itching.
This stage is characterized by a halt in the growth of the main lesions. Around the psoriatic plaques, specific folds are formed.
At this stage, there is a decrease in the severity of all the main symptoms. Plaques begin to disappear, and in their place for some time, areas of skin with altered pigmentation are retained.
The first signs of psoriasis:
- Feeling of general weakness.
One of the earliest and most common manifestations of this disease is psoriatic rashes, in some parts of the skin.
The peculiarity of the rashes is that when located on the scalp, joints and lower back they are located symmetrically. At the initial stages of the development of this disease the size of the lesions is insignificant, about several millimeters, however, as they develop, they can increase and reach up to 10 centimeters.
The features of plaques make it possible to isolate such forms of psoriasis as:
With this form of disease, lesions are small, with approximately the head of the pins.
The shape of the rash is like a drop of a small size.
The lesions are rounded, with brightly pronounced edges. The top layer of lesions is formed from the scales of keratinized skin. At the initial stages of development, the scales form in the center of the lesion, and as the disease progresses, the scales diverge to the edges. The luminescence and friability of the stratified layer is due to the presence of areas with air, which facilitate the separation of flakes. In addition, near the lesion is the formation of small red spots. In the area of these red spots, inflammation develops and the focus grows.
When removing the horny layer of skin, a smooth, pink surface appears in the area of the lesion. The appearance of this surface is due to the proximity of the capillaries and significant damage to their walls.
The most characteristic symptom of psoriasis of the scalp is the appearance of psoriatic plaques, which significantly rise above the skin. The lesions are covered with scales from dead skin. The development of this disease with this localization affects only the scalp, the hair is not prone to damage.
One of the characteristic features of this form of the disease is related to the fact that lesions can extend beyond the scalp and can be observed in the region:
- The ears.
Signs of psoriasis in men and women are approximately the same.
The main difference is that the signs of psoriasis in women are most often manifested in the area of the hands, since it is these areas of skin that are most often contacted with aggressive substances.
Another very specific form of this ailment is palmar-plantar. Its main symptom is a significant thickening of the skin in the affected areas. The skin itself gradually becomes less sensitive and more coarse. In the lesions it is possible to form significant cracks and corns. The cause of this phenomenon in the area of the palms and soles is accelerated cell division, in which the dead layer is not peeled, but is retained on the surface.
At the initial stages of development in the deep layers of the skin formation of pustules filled with a transparent liquid is observed, as the disease develops, the liquid becomes white. In the place of pustules, scars form with time. Most often this form of the disease manifests itself simultaneously in two areas, however, in some cases it can manifest only in one part of the body. If the disease covers the back side of the skin during development, then this psoriasis can not be considered palmar-plantar.
Very often there is a lesion of such a cutaneous appendage as the nails. With the defeat of the nails, there are quite a few different symptoms that indicate the development of psoriasis.
It is customary to distinguish several types of lesions:
For this type of lesion, the nail coating is characterized by small pits.
This type of lesion develops according to the shape of the nail fungus. The nail plate changes color, thickens and flakes. Under the plate is a special psoriatic papula surrounded by a red rim.
In addition, it is extremely difficult to understand what exactly this disease develops in a child and to determine its beginning. As for the main symptoms of psoriasis in children, they are quite specific. In addition, depending on the age of the child, the symptoms of psoriasis have significant features. For example, with the development of the disease in an infant, there are atypical symptoms. These include the appearance of redness in the folds of the skin, which are accompanied by exfoliation of the stratum corneum. Outwardly, such manifestations of psoriasis resemble small intertrigo.
Preschool children are characterized by the appearance of rashes in non-standard places:
- In the face area.
- In the genital area.
- In the place of natural folds.
Quite often the manifestation of foci of lesions is observed in the region of the scalp. It is also very common for the rash to appear in areas that are prone to constant friction and exposure to corrosive substances.
As the disease develops, psoriatic plaques increase significantly in size. With the drop-shaped form of the disease, lesions are usually of small size, however, they can be localized in significant areas.
One of the main features of the development of this disease in children is a long-term development. One of the easiest forms for a child is teardrop-shaped psoriasis, since it is accompanied by long periods of remission.
For the development of childhood psoriasis is characterized by 3 main stages:
At this stage, new lesions appear, which are accompanied by severe itching. In infancy, the main feature of this stage is the poor manifestation of capillary bleeding. Characteristic features include enlargement and consolidation of lymph nodes.
This stage of the disease is characterized by a halt in the increase in the main lesions and the appearance of desquamation in the area of damaged areas of the skin.
At this stage, the main lesions disappear. As they disappear, the level of severity of skin changes decreases. For the regression stage, normal functioning of the lymph nodes is characteristic. In some cases, in the area of the palms and soles, the child may have diffuse lesions or cracks. In severe disease, its effect can also be affected by nails.
Pustular form of the disease in children is extremely rare. It is considered the most difficult, requires in-patient treatment and, in addition, leads to a significant deterioration in health and temperature. Psoriatic arthritis in children is not found.
