How to judge is psoriasis

summary

This weekend, the weather is better. I went swimming with my classmates at the seaside. When I came back, I found that my back had little red spots and kept falling debris, which is very similar to psoriasis. Now let's learn how to judge whether it is psoriasis.

How to judge is psoriasis

First: silvery white scales, thin film phenomenon and punctate bleeding are regarded as the three clinical features of psoriasis symptoms, 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.

Second: 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. I suggest you go to the local regular institutions to check.

Third: the early symptoms of psoriasis are reddish papules. The papules are needle size at first, and then gradually develop to mung bean size. The papules gradually fuse into patches or macular papules, and the surface is covered with multiple layers of dry silver scales. After gently scraping off the scales, you can see translucent reddish thin film, which is called membrane phenomenon. After scraping off the film, you can see small bleeding points, which is called Auspitz sign. Most patients are suffering from psoriasis The rash is severe in winter and mild in summer, and itching or asymptomatic.
