What is the basis for the diagnosis of vitiligo

Basis 1: look at the shape of white spots. In the early stage of the disease, the patient's skin will appear white spots or incomplete plaques, nearly round, oval or irregular shape, there are also spot like spots at the onset of the disease, the boundary is more obvious; some edges are surrounded by pigment bands. The early symptoms of vitiligo in a few cases, white spots mixed with follicular punctate pigment proliferation, the latter can increase, expand and fuse into islands, white spots in addition to depigmentation, the affected area does not shrink or desquamate changes, white spots on the hair can lose pigment and even completely white, there are also hair unchanged for a long time.

Basis 2: the location of the lesion. Patients should also carefully observe their lesions, vitiligo may occur in various parts. In the face, neck, belt, sacrococcygeal, finger toe back, female bra belt or button compression, hernia support, anus, female perineum. This is because the exposed skin is easy to be exposed to the sun. After the sun exposure, due to the hyperfunction of melanocytes, the consumption of melanocytes will lead to early decline. It may also be due to the excessive production or accumulation of melanin intermediates synthesized by cells themselves, which will damage melanocytes and cause leukoplakia. The main cause of leukoplakia is local trauma.

Basis 3: you can first observe whether the white spot is smooth and does not crumble, which is generally realized as no pain and itching feeling. If the boundary is blurred or the white spot is expanding towards the normal skin, this situation can be preliminarily judged as the symptom of vitiligo, and the specific condition can only be diagnosed after seeing the white spot. For vitiligo related diseases, treatment is relatively long, but must be found early, early treatment, such damage will be smaller.
