First: psoriasis vulgaris It is the most common clinical type. In the initial stage, the typical lesions are red papules or macular papules, the size of needle to mung bean, with clear boundary, covered with multiple layers of silvery white or mica like scales, which are easy to scrape off. After scraping off, a layer of bright reddish film can be seen on the base, which is called membrane phenomenon. If you continue to scrape down, small bleeding spots appear on the surface of erythema, which is also called Auspitz sign.

Second: progressive stage: it is an acute attack stage, in which new skin lesions constantly appear, old skin lesions continue to expand, inflammation is obvious, and isomorphic reaction can occur, namely Koebner phenomenon. It refers to the skin lesions with the same nature as the primary disease after the stimulation of normal appearance skin, such as trauma, scratch, injection or acupuncture. Generally, the skin lesions appear 3-18 days after the injury, so there are strip scales in the scratch or surgical incision The possibility of psoriasis should be considered.
