The essence of psoriasis is accelerated, morbid epidermal cell hyperplasia - the so-called keratinocytes. The cause is an increased number of cell divisions in the epidermal layer and an abnormal cycle of maturation of these corneal epithelial cells. The result is efflorescence in the form of flat-hardened lumps of various sizes.
Psoriasis efflorescence - flat-hardened papules
The psoriatic plaques are red. They are clearly delimited from the surroundings, because they are covered with silvery scales. Scales are a product of abnormal keratosis. After scraping off a single 'scales' a shiny gloss appears, followed by punctate bleeding. This bleeding is due to the damage to the vessels in the elongated skin nodules.
The development of follicular efflorescence
P efflorescence is initially small clumps of pin-head size (psoriasis sowing), which, by spreading the circumferential diameter, can reach a size of several-several centimeters (plaque psoriasis). An example of this is small clots - typical for the beginning of disease symptoms, eg after infections.
The growth of efflorescence in the form of plaques
The shape of skin eruptions is highly varied in patients. They can grow into large plaques that are spreading circumferentially, like circles after throwing stones into the water. In the case of advanced disease, so-called ring efflorescence with intensification of changes on the circumference and regression in the center.
Number and area of efflorescence
The number of eruptions in patients can be highly variable. They may be single lumps or plaques or very numerous in the entire body in the so-called during sowing. Depending on the advancement of the patient's gourmal outbreaks, the patient is treated ambulatory or directed to intensive treatment in the hospital.
Psoriasis often attacks nails
In psoriasis, changes on the nails are often characteristic. They are punctate hollows, longitudinal or transverse furrows. Sometimes subungual hyperkeratosis also appears, lifting the nail up or coloring it in brown and yellow. The tile can then become brittle, thick and dull, which imitates the symptoms of onychomycosis.
TYPES OF PSYCHOLOGICAL SYMPTOMS
Location of psoriatic lesions
Efflorescence of psoriasis vulgaris (they can arise anywhere on hairy and smooth skin as well as in the genital area.) N the most often appear on over protruding bone points (elbows, knees, hands, cruciform region). They are accompanied by, more or less numerous, localized lesions on the torso or around the folds of the skin (armpits, groin, etc.).
The picture of the disease affects the type of psoriasis symptoms
There are 4 basic types of psoriasis:
- psoriasis vulgaris,
- pustular psoriasis (psoriasis pustulosa)
- psoriasis of the joint (psoriasis arthropatica)
- psoriatic erythroderma (erythrodermia psoriatica), when the entire skin is affected by the inflammatory process.
Typical forms of psoriasis symptoms
The size and shape of the efflorescence and location of lesions allows to distinguish several types of psoriasis vulgaris, pustular and joint pain. In some cases, peripheral dissemination of efflorescence is accompanied by regression of changes in the middle, which gives a picture of ring-like, polycyclic, sometimes percolated changes in the periphery (annular). Individual efflorescence tend to merge with each other, causing the formation of large areas of skin affected by disease, sometimes with irregular shapes resembling the outlines of continents (geographical - plaque).
Occupation of the entire skin with psoriatic lesions
This form of psoriasis (psoriatic erythroderma) may theoretically concern every patient in the case of the intensified effect of numerous disease factors and discontinuation of treatment. In such advanced psoriasis, the patient is directed to intensive treatment in the hospital.
Common psoriasis of hairy skin
The symptom of this form of the disease is excessive keratosis and exfoliation of the scalp. This form of psoriasis sometimes moves partly to the front of the patient. The scaly scalp does not cause weakness and hair loss. Hair loss in the course of psoriasis is mainly due to the paternity or mechanical irritation of the skin as a result of pruritus, which is accompanied by the disease.
Nail psoriasis
This form of the disease is often accompanied by psoriasis. Nail changes are characteristic and therefore constitute an important diagnostic element. Initially, there are few punctuated recesses on the surface of the nail plate (fibrillose nails), which may be accompanied by brown-yellow discolorations under the nail plate (a sign of oil stain). Both phenomena are the result of an abnormal keratosis process. The lesions may affect one hand or foot nail, but they usually occur on a few nails even with little skin involvement and vice versa.
