summary

My sister didn't know what she was exposed to. There were a few red spots on her arm. After all, it was the girl who cared about it. She went to the hospital and said that it was the early stage of psoriasis, which made us very strange. Is this the symptom of psoriasis? Now let's learn how to diagnose the symptom of psoriasis.

How can psoriasis symptom be diagnosed

First, 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.

Second, the most common type is common in clinic. The skin lesions are various in shape, such as drops, coins, maps, rings or loops, and oyster shells. The three clinical features of typical skin lesions are silvery white scale, membrane phenomenon and cribriform hemorrhage. The rash usually occurs on the scalp and limbs. At the initial stage, it is a red papule with the size of millet to mung bean, which is in the form of drops and increases rapidly to form a macular papule or plaque. It can fuse into a piece with clear edge and infiltration. The erythema is covered with multiple layers of silvery white scales.

Third: psoriasis lesions can occur symmetrically in any part of the body. Most of them are in the elbow, knee extension and head. In a few patients, the nail and mucous membrane can also be invaded. It should be noted that there are many kinds of skin diseases, and it is better for patients not to judge or use drugs by themselves. If skin abnormalities are found, it is better to make a reasonable diagnosis at the first time to the regular medication for skin diseases, and then treat the patients with symptomatic medication.

Compared with most other skin diseases, the symptoms of psoriasis are still very obvious, but in the early stage of the disease, the symptoms are often not painful and itchy, which is easy to be ignored. It is suggested that if there are symptoms of psoriasis, it is better to go to the hospital for diagnosis and treatment as soon as possible.
