Psoriasis, also known as psoriasis, is one of the most persistent skin diseases, and the occurrence of this disease not only makes patients suffer from physical pain, but also from internal torment. For psoriasis, the initial treatment is quite important, but some patients are unaware of the initial symptoms of psoriasis and delay the treatment. In order to avoid this situation, I will introduce you to the initial symptoms of psoriasis. Psoriasis is a chronic disease that generally occurs on the extremities, trunk or scalp. The skin is scaly and thickened locally, and children are generally susceptible to the disease at the age of 10 or older. The rash is usually not itchy, but it is uncomfortable and the child may be bothered by the appearance of the skin. In the early stages of psoriasis, the patient will have a distinct scaly appearance. Psoriasis has a variety of symptomatic manifestations, and the initial symptoms show thick grayish or grayish-yellow scales covering the lesions, which are generally more common in severe cases of head psoriasis, and the scales tend to fall off and often feel itchy. The typical skin manifestation of psoriasis is a well-defined red patch with silvery-white scales. In the early stages of psoriasis, patients will show obvious scales in addition to a well-defined rash of spots, which is a common symptom, starting as a red dotted rash of corn to soybean size, the early symptoms of psoriasis also show that with the development of the disease, the rash will gradually expand more and more, and even fuse with each other into pieces, the bottom infiltration is obvious, the edges are clear, surrounded by an inflammatory red halo, in the shape of droplets, maps, disks The rash may appear to be pitting, map-like, discoid, or oyster shell-like. The initial stage of psoriasis is a pinhead to lentil-sized inflammatory flat papule, which gradually grows into a coin or larger light red moist spot covered with multiple layers of silvery white scales. When the exterior scales are gently scraped away, a light red shiny translucent film is revealed, called a thin film appearance. The same scraping away the film will present small bleeding spots, often referred to as punctate bleeding appearances.
