The symptoms of psoriasis

The reasons for the development of the disease

The causes of psoriasis is not fully understood. Medicine and patients ' experience confirm the impossibility of the transmission of disease by contact. The disease most often appears in the period from 18 to 25 years, comitatus hyperemia on the patient's body.

Causes of psoriasis:
  • diseases of the endocrine system;
  • the weakening of the immune system;
  • genetic predisposition;
  • causes of psoriasis can be to develop viral infections;
  • parasitic invasion;
  • there is a common factor in the development of the disease include stressful situations and emotional turmoil of nerves;
deficiency in trace elements and vitamins</1_img>
  • deficiency in minerals and vitamins.
Note, however, that the factors in the development of the disease can be quite varied, as medicine finds new reasons that provoke negative symptoms of the disease.

The symptoms of psoriasis stages

The disease can occur in 4 stages:
  1. the initial (early);
  2. progression;
  3. stationary;
  4. regression.
The severity of the disease depends on the particular symptoms of psoriasis in the patient.

The symptoms of psoriasis initial (first) stage. The primary symptoms of the disease at an early stage occur with the emergence of epidermalibus papular rash. After 2-3 days it formed of silver-white scales that are easily removed (see photo). Initial symptoms were classified as the development of the "point" of psoriasis.


Stage of progression. This stage is characterized by active growth and the subsequent merger of the papular rash. The primary signs of progression are manifested the characteristic flaking present on the Central part of the element without affecting the peripheral rim.

Secondary signs of progression characterized by the presence of symptom Kebnera (isomorphic peripheral reactions). When injury papular area after 6-8 days (in accordance with the form of injuries) there is an element of psoriasis. In addition, the phenomenon Kebnera observed, if any psoriatic elements provoke strong scalpendi on the hands, elbows, legs, face.

Progressive stage is accompanied by painful itching, which is not typical for other stages. Generally, the progression can last 2-3 weeks and up to 3 (or more) months. During the stage of progression is recommended prophylactic administration of hormonal therapy and external means.

Stage stationary. This stage replaces the progressive and has no specific time boundaries. It is able to flow smoothly into the regression, the final form of the illness, but able to progress further. To characteristic symptoms of the stationary phase of psoriasis is the suspension of growth of plaques and prevent the emergence of new papular rash on the face, hands, elbows, etc.

Stage stationary</2_img>

In this case, there has been increased peeling, 50% of patients occurs psevdoatrofiya classified as the Corolla Voronov. On peripheral papules occurs angustus strip light skin, which resembles tegimentum paper from cigarettes.

Stage regression. This stage completes the process of inflammation with a characteristic decrease in peeling, aequandi the Central part of the psoriatic elements with their further resolution (photo). psoriatic elements can be of different shapes (rings, trapeze, arc, etc.) and are classified as "geographical psoriasis."


There is another option regressus stage of the disease, if the resolution starts from a peripheral region of the papules without forming scar tissue, and in the absence of atrophic processes. In that part of the body where there are papules may appearance of hyperpigmentation. Note that this separation of the disease on the option is conditional. Most often regressus stage is determined by observing symptoms of the patient.

The symptoms of psoriasis depending on its shape

Currently, there are many psoriatic forms that differ from each other in external signs and the severity of symptoms.

The most common forms of psoriasis:

  • seborrheic psoriasis the scalp;
  • vulgar;
  • longus;
  • psoriatic arthritis rheumatoid
  • exudative
  • teardrop-shaped;
  • nail;
  • pustular;
  • erythroderma.

Common forms of the disease are TABULA and psoriasis vulgaris. Be aware that any kind of disease there is redness and itching.

TABULA PSORIASIS. This kind of disease develops rapidly, sometimes in the nervous system and occurs with acute symptoms. Disease begins with the appearance of a small amount of scaly papules that are clearly limited and slightly protrude above the surface (pictured). In the future, papules may join together, forming plaque.


This kind of psoriasis are able to affect large areas of the skin, causing an uncomfortable condition of the patient. When injury plaques may develop bacterial and fungal infections. Refinement of the disease diagnosis is carried out using a confirmation of "psoriatic triad".

VULGAR FORM OF PSORIASIS. This type of psoriasis is accompanied by active papular and genus TABULA, peeling scalp, back, hands, elbows, feet. Rash covered with silvery-white loose statera dolosa and has a clear bright red (pink) border (pictured). In the diagnosis of the skin manifested positive signs of "psoriatic triad".

Rashes appear in the local areas (elbows, scalp, etc.) in 1-2 weeks. This rash is called "guard" or "duty". For some patients the papules turn into erythroderma. Very rarely vulgar form appears on the face and in the genital area.

SEBORRHEIC PSORIASIS. This disease is localized on the scalp and is characterized by severe flaking of the head, ears and forehead. Such symptomatology is called "psoriatic crown" (see photo). In the future the crust crack, and diseased skin (especially in children) strongly rursus and itchy that is a great discomfort to the patient. As a rule, the disease has a seasonal development, it is sometimes possible its appearance in connection with increased nervous excitability of the patient. In violation of the immune system may cause fungal infection, which significantly impairs the disease.

The disease diagnosis is difficult because seborrheic psoriasis like seborrheic dermatitis its symptoms, however, seborrheic psoriasis no hair loss. By palpation (feeling) of seborrheic psoriasis defines clear borders of plaques, and seborrheic dermatitis has these boundaries.

EXUDATIVE FORM. This disease develops in patients with disorders of the endocrine system (diabetes, obesity). Exudative psoriasis often seen in the elderly, possible adverse symptoms in a child.

The main characteristic of this form of psoriasis is the absence of white scaly deposits on the papules. Instead, the rash can be covered with yellow-brown crustae that triggered by an excessive release of exudate (inflammatory liquid). It coats the scales of the rash. When removing the crusts exposed erosiva wet surface. Typical psoriasis papules do not exist, and is edematous inflamed area of the body with blurred boundaries.


Most commonly lesions are located in the skin folds (genitals, armpits, under the breast), flexura surface on the hands and feet. If the patient has varicose veins, symptoms of exudative psoriasis of the lower extremities are enhanced.

THE NAIL PSORIASIS. This type of psoriasis is characterized by lesions of clavus plates in the form of point depressions, which are called "symptom thimble". The nail becomes dull, the outer edge of the affected nail shows a red rim. It is noted friability okolonogtevogo roller and the destruction of the structure of the nail. It should be noted that similar symptoms were observed with the development of onychomycosis, so requires careful diagnosis.
