What is psoriasis like? How do you get psoriasis?

Psoriasis is a common and predisposing chronic inflammatory disease. It is not fully understood, but trauma, trauma, surgery, menstruation, pregnancy, and food may be precipitating factors or worsening lesions.

The disease begins as an inflammatory flat papule the size of a needle to a lentil, which gradually increases to a coin or a larger reddish infiltrate, with a well-defined border, covered with multiple layers of silvery-white scales. Gently scraping off the surface scales reveals a translucent film with a light red glow, which is called the film phenomenon. If the film is scraped again, small bleeding spots appear, which is called punctate bleeding.

During the development of the disease, the morphology of the lesions can manifest itself in many forms. In the acute phase, the skin lesions are mostly guttate, bright red, and pruritic. Lesions in the quiescent phase are often plaques or maps.

Regressing lesions are often annular or semi-annular. A few rashes have thicker scales on them, sometimes piling up like shell oysters.

Lesions can occur symmetrically anywhere on the body. It is more common on the extensor side of the elbow and knee and head. In a small number of patients, the nails and mucous membranes may also be affected.

Psoriasis due to the excessive proliferation of keratinocytes and various biochemical and metabolic disorders, resulting in the aging epidermal cells have not fallen off, and new epidermal cells have emerged, so the epidermal cells with incomplete differentiation are rapidly accumulated, and they begin to be miliary-sized erythema, and soon silvery-white scales appear on the surface, which can be peeled off by gently scraping them, and with the resistance of the damaged cells, the skin lesions expand to the periphery, fuse with each other, and finally gradually form patches of different sizes, which are divided into vulgaris, erythroderma, arthritis, and pustule types.

Psoriasis is a common chronic inflammatory form of a red rash covered with grayish-yellow or whitish scales that peel off and reveal a red rash when scraped off. The disease is a combination of genetic and environmental factors, a variety of factors interact, polygenic inheritance tends to occur throughout the body, with the extensor side of the scalp and limbs as the common symmetry.

It is recommended to go to the ** department of a regular, large, and professional hospital for treatment. We must go to a regular professional hospital, conduct a systematic examination under the guidance of a doctor, and formulate a personalized plan according to the patient's inducement and other conditions, so that we can recommend that the patient accept it in time, and it is taboo to delay the time, which will only aggravate the condition.

Psoriasis is a more common disease in our lives, and psoriasis is also a chronic inflammatory disease, which is generally more common among young people, not only in addition to young people, people of other ages will also have psoriasis.

1.Heredity is what causes psoriasis. Clinically, there is often a family history and a genetic predisposition.

30% to 50% of people with family history have been reported abroad, and some people even emphasize that it is up to 100%. About 10% to 20% of those with a family history have been reported in China, and some people believe that it is autosomal dominant inheritance with incomplete penetrance, and some people believe that it is autosomal recessive inheritance or sex-linked inheritance. The incidence of psoriasis in the descendants of one parent is three times higher than that of the healthy child, and the incidence is higher in the descendants of both parents who have psoriasis.

2.Infect. Clinical practice has shown that the onset of psoriasis is associated with upper respiratory tract infections and tonsillitis.

Six percent of patients with psoriasis have a history of pharyngeal infection. We have found that psoriasis in many children is closely related to tonsillitis. For example, a mother and her three children had acute tonsillitis at the same time, and after the disease was controlled, three of them developed psoriasis.

In this case, antibiotics** are effective. The rash may improve or resolve markedly after tonsil removal, suggesting that infection is an important factor in the onset of psoriasis.

3.Metabolic disorders. Studies of psoriasis blood chemistry, histochemistry and pathophysiology have failed to yield beneficial results. In the past, it was thought that the onset of psoriasis was related to disorders of lipid metabolism. This is also a factor that causes psoriasis.

The above is the common ** of psoriasis, although the high incidence of psoriasis is some young people, but for the prevention of psoriasis in addition to young people, each of us should pay enough attention, once psoriasis "sticked" for a long period of time may be "entangled" with you, rather than looking around for a doctor, it is better to do the corresponding prevention work as soon as possible.

It is not certain just by looking at it, you have to do a skin test, and some bacterial infections look the same as psoriasis.
