What is the precursor of psoriasis

On the one hand, the skin lesions of psoriasis are usually inflammatory red papules, with millet to mung bean size, and then gradually expand or fuse into brownish red plaques, with clear boundary, inflammatory halo around, obvious basal infiltration, and multi-layer dry silver white scales on the surface.

On the other hand, there are papules and erythema of different sizes. The surface is covered with silvery white scales and the boundary is clear. They are mainly distributed on the scalp, extension of limbs and back. There are more males than females. It is easy to relapse or aggravate in spring and winter, but it is easy to relieve in summer and autumn.

Third, gently scrape off the scales on the surface to expose a layer of light red and shiny translucent film, which is the spinous cell layer in the epidermis, which is called membrane phenomenon; then scrape off the film to reach the top of dermal papillary layer, where the capillaries are scraped, there will be small bleeding points, which is called punctate bleeding phenomenon.
