summary

Psoriasis is a common skin disease. When I went to play with water yesterday, I found a large white thing on my friend's back, which looked like dandruff. Later I learned that it was psoriasis. Now let's make a popular science about the symptoms of psoriasis.

What symptom does psoriasis have at the beginning

First, the initial lesions are often red packets or brownish red dots or macular papules, with dry scales, and then gradually expand into brownish red patches with clear boundaries, and the adjacent ones can fuse with each other. The scales are silvery white and gradually thickened. When scratching, scales fall in pieces, exposing the red smooth base surface, which is called film phenomenon. When peeling off the film, there are small punctate bleeding with the size of a needle. This kind of film like bright red surface with punctate bleeding is called ospitz phenomenon.

Second: the initial symptoms of psoriasis are silvery white scales, membrane phenomenon and punctate bleeding, which are regarded as the three clinical characteristics of psoriasis symptoms, and also known as the "three steps of psoriasis". The skin lesions of psoriasis usually start with inflammatory red papules, which are big from millet to mung bean, then gradually expand or fuse into brownish red plaques, with clear boundary, inflammatory red halo around, obvious basal infiltration, and the surface is covered with multi-layer dry silver white scales.

Third: gently scrape off the surface scales, then expose a layer of light red and shiny translucent film, which is the spinous cell layer in the epidermis, called the film phenomenon; then scrape off the film, that is, to reach the top of the dermal papillary layer, where the capillaries are scraped, there are small bleeding points, called the punctate bleeding phenomenon. If you have the above similar symptoms, it is recommended that you should treat them in time.
