Stage of development

There are three stages of psoriasis:

1. Progressive — new rash, the patient was worried about the intense itching.
2. Fixed — the appearance of new lesions stops already beginning to heal.
3. Regressiruyushayf — psevdoatroficheskie are formed around the centers of the wheels, in the center of large plaques visible in areas of the health of the skin; however, the disease is similar to the hyperpigmentation in the affected areas on the site where the skin is more dark than the healthy colour.

Also psoriasis usually klassificeret by gravity to the light (lose less than 3% of the surface of the skin), moderate (with lesions from 3 to 10 percent of the surface of the skin), and severe (involving more than 10 percent of the surface of the skin). Joint damage is considered as a severe form of psoriasis, regardless of the affected area of the skin.

Psoriasis and its symptoms are characterized by homogeneous rash in the form of plates with a diameter of 1-3 mm 2-3 cm, pink-red, covered sitting silvery-white scales. The result of the regional growth elements may coalesce into plaques of various sizes and forms, sometimes occupying extensive areas of the skin. Plates normally found on the skin razgibatelnoy surfaces of the extremities, especially the elbow and knee joints, torso and the scalp.

1. Blyashkovidnyi psoriasis, or plain psoriasis, psoriasis vulgaris, simple psoriasis (psoriasis vulgaris) (L40.0) is the most common form of psoriasis. It is observed in 80 % — 90% of patients with psoriasis. Blyashkovidnyi psoriasis vulgaris most often manifests itself in the form of a typical on the surface of the healthy skin sites inflamed, red, hot skin, covered with gray or silvery white, scaly, dry and thickened skin. Red skin under the easily removable color gray or silver layer is easily damaged and bleeds, as it contains a large number of small blood vessels. These sites are typical psoriatic lesions are called plaques psoriaticheskimi.Psoriaticheskie plates tend to increase in size and fuse with the neighboring plates, forming the whole of the plate of plates ("paraffin lakes").
2. Psoriasis sgibatelnyh surfaces (flexural psoriasis), or "inverse psoriasis" (inverse psoriasis) (L40.83-4) usually appears as a smooth or with a minimum of peeling, not especially prominent on the surface of the skin, flaming red points, which are found exclusively in the folds of the skin, with no or minimal lesions in other areas of the skin. Most often, this form of psoriasis affects the folds of the vulva, groin, inner thighs, underarms, under the folds increases when there is excess of weight of the stomach (pannus psoriatic), and in the skin folds under the Breasts of women. This form of psoriasis is particularly vulnerable to deterioration under the influence of the friction injury to the skin and the sweat, and it is often accompanied or complicated by secondary infection by fungi or streptokokkovoy piodermiey.
3. Guttate psoriasis (guttate psoriasis) (L40.4) is characterized by the presence of a large number of small, dry, red or purple (even purple), in a manner similar to the drops, tear or small dots, circles, elements of destruction. Psoriaticheskie these items are normally usipayut a large area of the skin, most commonly the thighs, but can also occur in the forearms, shoulders, scalp, back, neck. Guttate psoriasis is often the first develops or worsens after streptokokkovoy of infection in typical cases — after streptokokkovoy sore throat or streptokokkovogo faringita.
4. Pustulyozniy psoriasis (L40.1-3, L40.82) or exudative psoriasis is the most severe skin forms of psoriasis appears raised above the surface of the healthy skin vesicles or blisters filled with clear akssudatom inflammatory (pustules). The skin under and on the surface and around the pustules is red, hot, inflamed and thick, peels off easily. There may be an infection secondary of the pustules, in this case, the exudate becomes purulent. Pustulyozniy psoriasis may be limited, localized, with the most frequent localization are the ends of the limbs (arms and legs), that is to say, the lower part of the leg and of the forearm, is called palmoplantarniy pustulyoz (palmoplantar pustulosis). In other more serious cases Pustulyozniy psoriasis can be disturbing, with widespread pustules across the surface of the body and the tendency to merge them into larger pustules.
5. Nail psoriasis or psoriaticheskaya onihodisrtofiya (L40.86) leads to different changes in the appearance of the nails on the fingers or of the feet. These changes may include any combination of color change of the nail and nail bed , the appearance of the nail and the nail points, spots, thickening of the skin under the nail and around the nail bed, separation and thickening of the nail, complete loss of nails (oniholizis) or the development of increased brittle nails.
6. Psoriatic arthritis (L40.5), or psoriaticheskaya artropatiya, artropatichskyi psoriasis is accompanied by inflammation of the joints and connective tissue. Psoriatic arthritis can affect any joint, but most often the small joints of the phalanges distal of the fingers of the hands and/or feet. Typically, it causes inflammation of the fingers and toes known as psoriatic daktilit. Psoriatic arthritis can also affect the tazobedrenye, knee joints,plechelopatyi the joint, the joints of the spine (psoriatic spondylitis). Sometimes psoriatic arthritis knee or hip joints and especially psoriatic spondylitis is more pronounced, which leads to the disability of the patient, the inability to move without special tools. The mortality rate in these most severe forms of psoriatic arthritis is greater, since the immobilization of the patient in the bed contributes to pressure sores and pneumonia. Approximately 10 to 15 percent of patients with psoriasis also suffer from psoriatic arthritis.
7. psoriaticheskaya aritrodermiya (L40.85), or aritrodermicheskyi psoriasis appears general, often disturbing inflammation and desquamation, otsloykoy the skin on the whole or a large part of the surface of the skin. Psoriaticheskaya aritrodermiya can be accompanied by intense itching, edema of the skin and subcutaneous tissue,the skin of pain.psoriaticheskaya aritrodermiya is often the result of the exacerbation of psoriasis vulgaris in its unstable course, especially when a sudden abrupt cancellation of therapy for systemic or local glucocorticoids. It can also occur as a result of the provocation, alcohol, neuro-mental stress, interkurrentnymi infections (such as colds). This form of psoriasis can be fatal, because of the extreme inflammation and peeling or exfoliation of the skin break the body's ability to regulate body temperature and the function barrier of the skin, which can be complicated by the widespread piodermiey or sepsis. However, a limited, localized psoriaticheskaya aritrodermiya may even be the first symptom of psoriasis, later it was transformed into vulgar blyashkovidnyi psoriasis.

The symptoms of psoriasis vary depending on the particular season and the stage. Many patients experience "winter" variety of the disease, where periods of exacerbation there in the late fall or winter. The disease

Psoriasis is a chronic disease, characterized by undulating course, with periods of spontaneous or provoked by these or other health effects remissiy or improvements and periods of spontaneous or provoked by adverse external influences (alcohol, interkurrentnye infections, stress) recurrences or exacerbations.

The severity of the disease may vary in different patients and even in the same patient during the periods of remission and exacerbation in a very wide range, from small local lesions to fully cover the whole body psoriaticheskimi plates.

Often there is a tendency to the progression of the disease over time (especially if untreated), to the weighting and the increase in the frequency of exacerbations, increase the area affected, and the involvement of new areas of the skin. In some patients, there is a continuous course of the disease without spontaneous remissiy , or even a continuous evolution. They also often affects the nails of the hands and/or feet (psoriaticheskaya onihodisrtofiya). Nail involvement may be isolated and observed in the absence of skin lesions.

Psoriasis can also cause inflammation of the joints, the so-called psoriaticheskuyu artropatiyu or psoriatic arthritis. Of 10% to 15% of patients with psoriasis also suffer from psoriatic arthritis.
