The symptoms of psoriasis

The causes of the development of the disease

Causes of development of psoriasis to finally have not been studied. The medicine and the patient experience confirm the inability of the transmission of disease by contact. The disease often appears in the period from 18 to 25 years old, comitatus hyperemia on the body of the patient.

The causes of psoriasis:
  • diseases of the endocrine system;
  • the weakening of the immune system;
  • genetic predisposition;
  • the causes of psoriasis can be the development of viral infections;
  • intestinal infestations;
  • the common factors of the development of the disease include a situation of stress and emotional turmoil on the nervous system;

  • deficiency of trace elements and vitamins.
Note, however, that the factors of the development of the disease can be very different, as the medicine finds new triggers of the negative symptoms of the disease.

The symptoms of psoriasis in different stages

The disease may occur in 4 phases:
  1. the initial (previous);
  2. progression;
  3. fixed;
  4. regression.
The severity of the disease depends on the characteristics of the symptoms of psoriasis of the patient.

The symptoms of psoriasis, initial (first) phase. The primary signs of the disease in the initial phase to proceed with the appearance epidermalibus mucinosis skin rashes. After 2-3 days on it to form silver-white scales, which easily are removed (in the photo). Initial symptoms classified, such as the development of a "point" of psoriasis.

 

The stage of progression. This phase is characterized target growth and, following the merger mucinosis skin rashes. The primary signs of progression are manifested the characteristic peeling, present in the central part of the element, without affecting the peripheral whisk.

Secondary signs of progression are characterized by the presence of symptoms Kebnera (isomorphic peripheral reaction). When lesions mucinosis field after 6-8 days (based on printed form injury) occurs, an element of psoriasis. In addition, the phenomenon Kebnera observed, if any psoriatica elements cause strong scalpendi on the hands, in the area of the elbows, feet, face.

The progressive phase is accompanied by a painful itch, it is not characteristic for the other phases. Usually, the progression can last 2-3 weeks and up to 3 (or more) months. During the stage of progression it is recommended that the prophylactic administration and therapy hormonal external means.

The stationary phase. This phase is replaced by progressive and do not have particular time limits. She is able to easily pour in the regression, the form of the disease, but is capable of further progress. The characteristic symptoms fixed phase of psoriasis applies to the suspension of growth of the platelets and prevent the occurrence of new mucinosis rash on the face, hands, in the area of elbows, etc.

In this case, there has been a strengthening of the peeling, 50% of patients occurs psevdoatrofiya, классифицируемая, such as the corolla Voronov. On the peripheral папулах occurs angustus strip of clear skin, remember tegimentum the cigarette paper.

The regression phase. This phase ends when the process of inflammation with the characteristic reduction of the peeling, aequandi central location psoriatica elements with their further resolution (in the photo). psoriatica elements can be of different shapes (rings, trapeze, bow, etc.) and are classified as "geographic psoriasis."

 

There is another option regressus initial phase of the disease, when the resolution begins with the peripheral part of the papules do not form scar tissue, and in the absence of atrophic processes. In that part of the body, where they have been observed papules is possible the appearance of hyperpigmentation. You must consider that this division of diseases the options is conditional. Often regressus phase determined by the method of observation of the symptomatology of the patient.

The symptoms of psoriasis depending on its shape

Currently, there are many psoriatica forms that differ from one another, the outward signs and the severity of the symptoms.

The most common are the following types of psoriasis:

  • seborrheic dermatitis, psoriasis of the scalp;
  • vulgar;
  • longus;
  • rheumatoid rheumatoid arthritis psoriatic
  • exudative
  • the shape of a drop;
  • TABULA
  • nail;
  • pustular;
  • erythroderma.

The most common forms of the disease are TABULA and psoriasis vulgaris. You must consider that every form of disease, redness, and itching of the skin.

TABULA PSORIASIS. This type of disease develops quickly, sometimes nervous, and proceeds with severe symptoms. The disease begins with the appearance of a small amount of flakes of papules, which are clearly limited, and protrude slightly above the surface (in the photo). Later papules may join together, forming platelets.

This type of psoriasis can affect large areas of the skin, causing uncomfortable condition of the patient. When lesions of the platelets allows for the development of fungal and bacterial infections. Improvement diagnosis of the disease is made with the help of confirmation "psoriatica triad".

VULGAR FORM OF PSORIASIS. This type of psoriasis accompanied active mucinosis and genus TABULA, flaking of the scalp, back, hands, elbows, feet. The eruption is covered with silver-white loose statera intentional and has a clear bright red (pink) as the border (in the photo). When the diagnosis on the skin registered positive signals "psoriatica triad".

Skin rashes appear in the local places (on the elbows, scalp, etc) after 1-2 weeks. This eruption is called the "guard dog" or "duty". Of a particular category of patients papules converted into erythroderma. Very rarely vulgar form it manifests itself on the face and in the genital area.

SEBORRHEIC, PSORIASIS. This type of disease is localized to the scalp, and characterized by a strong desquamation of the head, the ears and forehead. Such symptomatology is called "psoriatica corona" (in the photo). Below the crust to crack, and the sick of the spots on the skin (especially a child) highly rursus, and itching, which leads to a huge discomfort to the patient. Usually, the disease has a seasonal development, perhaps its appearance in a relationship with a greater nervous excitability of the patient. In the case of a breach of the immune system, perhaps the appearance of a fungal infection, which greatly aggravated the disease.

The diagnosis of the disease is difficult for seborrheic dermatitis, psoriasis is similar to seborrheic dermatitis for the symptoms, however, when seborrheic psoriasis is lacking hair loss. With palpation (sensitivity) seborrheic psoriasis causes clear boundaries, and seborrheic dermatitis has no such limitation.

EXUDATIVE. This type of disease develops in patients with disorders of the endocrine system (diabetes, obesity). Exudative psoriasis often can be observed in the elderly, can be negative symptomatology of the child.

The main feature of this type of psoriasis is the lack of white flake of plaque on the папулах. Instead, the rash may be covered with yellow-brown crustae, which resulted in excessive release of exudate (inflammatory liquid). Wrap the slivers of skin rashes. If you remove the crust, which is exposed erosive surface wet. Typical papules of psoriasis is lacking, and appears edematica inflamed area body with blurred boundaries.

 

Most often precipitation is found in the folds of the skin (genitals, armpits, under the breasts), flexura surface on the hands and feet. If the patient observes varicose veins, exudative psoriasis symptoms of the lower limbs are amplified.

THE NAIL PSORIASIS. This type of psoriasis is characterized by a loss clavus plates in the form of depressions point, referred to as the "symptom thimble". The nail becomes dim, the outside edge hit the nail appears inflamed hem. It is observed friability okolonogtevogo cushion and the destruction of the structure of the nail. It is necessary to underline that a similar symptoms observed with the development of onychomycosis, therefore, necessary for an accurate diagnosis.
