White furuncle, the name of TCM dermatosis. It is equivalent to psoriasis in western medicine, characterized by erythema and loose silvery scales on bleeding spots, similar to thin films and dewdrops. Ancient Chinese medicine called it "white furuncle", and ancient medical books also called it psoriasis. Western medicine called psoriasis, commonly known as psoriasis.
It is characterized by papules and erythema of different sizes, with silver scales on the surface and clear boundaries, which are common in scalp, limbs and back. There are more men than women. It is easy to relapse or aggravate in spring and winter, and it is more relieved in summer and autumn. Psoriasis is a chronic inflammatory skin disease with red color, thickened skin and long course.
This inflammation of psoriasis is not directly caused by infectious pathogenic factors such as bacteria, fungi or parasites. Modern medical tests have reached a fairly high level, but so far psoriasis has not been proved to be an infectious pathogenic factor. Clinical observation of psoriasis shows that there is no problem of infection, and various indications show that psoriasis is not contagious.
The etiology and pathogenesis of albino furuncle are not completely clear. It is generally recognized at home and abroad that it is the result of the joint action of genetic factors and environmental factors, that is, it is induced by many factors on the basis of genetic factors. 65438-0984 The epidemiological investigation report of albino furuncle in China shows that 32% people have a family genetic history, and the mode of inheritance is autosomal dominant inheritance, with an penetrance rate of 20%.
symptom
Different forms of furuncle lesions. It can not only reflect the stages of the disease, but also reflect the length of the course and the immediacy of treatment. For example, there are patches of white or brown spots scattered between erythema, indicating that it is not the first time for the patient to get sick. When the lesions do not subside for many years, the area of a single lesion is often large or multiple lesions merge with each other, and the lesions are often hypertrophic and form plaques.
People who occur in the scalp often appear in the early stage of the disease, often born on the hairline, in a band shape, sometimes fused into one piece, covering the scalp with thick scales, and the hair at the lesion and thick scales is dry and contracted into bundles, like a brush head. Sometimes the damage can extend to the front hairline and invade the forehead by several centimeters. When the whole body is seriously damaged, skin lesions can also appear on the face, mostly drops or red papules on the nails.
