Basic information
Before telling you how psoriasis begins, you should tell what this disease is.
According to experts,the disease in question has another name that sounds like scaly deprive. This is a chronic disease of non-infectious origin, or so-called dermatosis. As a rule, it affects the skin areas as well as the scalp.
Causes of the disease
The fact that such psoriasis, how the disease begins, is known to many. But not everyone knows why this pathological condition arises.
Many modern experts suggestthe autoimmune nature of psoriasis. In other words, scaly versicolor is an abnormal reaction of the body to the effects of any external stimuli, as a result of which the upper layer of the skin dies on the surface of the patient's body.
Currently, most doctors tend to believe that psoriasis is a multifactorial disease.
Theories of origin
Why does a disease such as psoriasis occur (how does it begin, will we tell below)? There are several theories about the origin of this disease. The first claims that there are 2 varieties of depriving:
- The first is due to poor performance of the human immune system. At the same time, psoriasis affects the skin, manifests itself at a young age and is inherited.
- The second occurs only after 40 years. In this case, the ringworm affects the nails and joints. It is not hereditary and is not associated with a malfunction of a person’s immune defenses.
As for the other theory, it states that the only factor contributing to the development of psoriasis is weakening of the immune system due to:
- infectious diseases;
- poor nutrition;
- cold climates;
- alcohol abuse.
In this case, the disease is classified as systemic. It can extend to joints and even internal organs.
Favorable factors
The appearance of the disease under consideration is favored by the following factors:
- excessive hygiene, which leads to a violation of the natural protection of the skin;
- dry and thin skin;
- HIV;
- constant contact with such irritating reagents as household chemicals, alcohol solutions, cosmetics;
- change of climatic region;
- consumption of alcohol or drugs, smoking (contribute to the deterioration of skin nutrition and blood supply);
- stress;
- taking certain medications;
- bacterial and fungal infections;
- the use of acidic foods, spicy dishes and chocolate;
- injuries;
- allergic conditions.
Symptoms of the disease
Теперь вы знаете, что представляет собой псориаз.How does the disease begin? Experts say that scaly zoster is a systemic pathology. In addition to its spread on the skin and nails, it can affect the area of the joints, spinal column, tendons, endocrine, immune and nervous systems. Also, this disease affects the liver, kidneys and the thyroid gland.
How does psoriasis begin (photo lichen presented in this article)? The first symptoms of this disease are:
- feeling of chronic fatigue;
- general weakness;
- depression or depressed.
Such signs are common. Unfortunately, it is rather difficult to determine from them that it is this disease that develops in a person.
Main clinic
How can psoriasis be detected?How does a person start getting sick? The main clinic of this disease is associated with damage to certain areas of the patient’s skin. The very first manifestation of scaly depriving are psoriatic plaques that cover certain parts of the human body. They are rounded papules pink or bright red.
The main feature of these lesions is theirsymmetrical arrangement on the flexion surfaces of the body, scalp and lower back. Less commonly, papules can be observed on the mucous membrane of the genital organs.
In the early stages of the development of the disease, the size of such plaques can be several millimeters. In the future, their value often reaches 10 cm or more.
Types of rash
Now you know what the beginning psoriasis looks like. It should be noted that the peculiarity of the rash appeared is the basis for the division of the disease into the following types:
- Tear versicolor. With such psoriasis, papules resemble a tear that corresponds to the size of regular lentil grain.
- Spot. Scales with this disease is less than a pinhead.
- Coin-shaped. This type of psoriasis is characterized by 5 mm plaques with rounded edges.
It is impossible not to say that sometimes psoriatic rash occurs in the form of garlands or rings, arcuate, and also in the form of a geographical map with jagged edges.
The rash feature
How does psoriasis on the hands begin? As mentioned above, such a disease can be recognized by the presence of scaly plaques. They represent the cornified epidermis and are the top layer of papules.
According to experts, in the verythe beginning of the scales are formed in the center of the plaque, and then gradually spread to its edges. The bright and friable appearance of such papules is due to the presence of air in the spaces between the cornified cells.
Also a clear sign of the onset of psoriasis ispink ring that forms around the rash. It is a zone of growth of plaque, as well as the spread of inflammation. In this case, the surrounding skin remains unchanged.
After the psoriatic plaque is removed,on the skin of the patient formed areas with a shiny surface of bright red color. As you know, they are formed by capillaries with thinned walls, which are covered with a thin film on top.
Such vessels are found due to disturbance.normal structure of the upper layer of the skin, as well as its significant thinning. In turn, the change in the structure of the skin occurs due to incomplete maturation of keratinocytes, which leads to the impossibility of their natural differentiation.
How does psoriasis begin in children?
Symptoms of scaly depriving children havesome differences. The first signs of this disease in babies are not typical. First, in their skin folds, there appears a demarcated area of redness, accompanied by maceration, as well as a gradual discharge of the stratum corneum (starting from the periphery). Sometimes this phenomenon is reminiscent of diaper rash, eczematids or candidiasis.
In a young child, psoriatic lesions appear in places uncharacteristic of this disease (for example, on the skin of the face, natural skin folds and mucous membranes of the genital organs).
Very often a scaly rash in children is formed onhead under the hair. It is a collection of crusts with moderate infiltration. Also a common area where plaques act is places exposed to aggressive drugs or constant friction of clothing.
Features of childhood psoriasis
Papules accompanying children’s psoriasis merge into plaques that have irregular shapes. As a rule, their sizes vary from lentil grain to a palm of the child.
When a teardrop-shaped variety depriving papular elements is small. They are formed suddenly, covering the face, body, neck, extensor areas of the legs and arms, as well as the scalp.
It should be noted that the psoriasis in children has a long and persistent course. The only exception is teardrop-shaped lichen, which is characterized by a mild course and a long period of remission.
Stage of the disease in children
As in adults, there are 3 stages in the development of childhood disease. Consider them in more detail.
At a progressive stage in the child appearsmall itchy papules that surround the red rims of peripheral growth. At the same time, in most children, the lymph nodes become thickened and enlarged, which sometimes become painful.
During the transition to the stationary stage, the growth of peripheral rims stops, after which, in the center of the plaque, infiltration is flattened, and peeling is reduced.
As for the regressive stage, itcharacterized by resorption of all elements of the rash. At this stage, around the plaques, a characteristic depigmented bezel can be observed. Further, areas of the rash lose their pigment or undergo even more pigmentation. At the same time, the child's lymph nodes are reduced in size and become soft.
