What symptom does the appearance of psoriasis have

summary

Psoriasis has three most typical symptoms, and these three typical symptoms often become the most effective way to diagnose the disease. The first symptom of psoriasis is to produce scales, the second is to cause peeling, and the third is to cause bleeding points. If a person has a skin disease with these three symptoms, it is most likely to be psoriasis. Psoriasis starts with a red, punctate rash about the size of a mung bean or a needle. Then the rash slowly expands and fuses into a whole.

What symptom does the appearance of psoriasis have

First: the spot rash caused by psoriasis will form a patch after mutual fusion. The surface of the patch will be covered with a layer of dry silver white scales. These scales can be gently scraped off by hand, and then you can see a layer of transparent film. This film can also be scraped off, and then you can see the bleeding spots.

Second: there are many pathogenic factors of psoriasis, and there is no specific cause of psoriasis. In general, psoriasis can be caused by heredity, autoimmunity, metabolic disorder or infection. In addition, mental disorders may also induce psoriasis.

Third: however, although psoriasis has three typical symptoms, different types of psoriasis also have some differences. For example, if it is erythroderma psoriasis, the skin lesions often appear diffuse red, and this disease can lead to 70% of the skin disease.

matters needing attention

Some psoriasis may be abscess type, which can spread all over the body within a few days after the onset of psoriasis, and there will be small abscesses in the skin lesions. These abscesses will fuse in a very short period of time, and eventually lead to high fever in the patient's body, accompanied by swelling and pain in the relevant joints.
