Is there a difference between halo mole and vitiligo?

Vitiligo is mainly the loss of melanin, and there are dozens of triggers, such as stress, emergency situations, trauma, decreased immunity, endocrine disorders, tyrosine, relative lack of copper ions, heredity, infection, post, etc., there are dozens of triggers, so **don't be blind**, be sure to find out where the root cause is, and then take the corresponding **. There are six main examination methods for the causes of vitiligo: 1. German Aumannwood lamp test 2, anti-melanocyte antibody test 3, microcirculation disorder detection 4, melanocyte deficiency detection 5, trace element detection 6, immune abnormality test.

It can comprehensively and scientifically and accurately detect the cause of melanin deficiency and the degree of damage to vitiligo. Provide a scientific basis for tailor-made programs for patients.

The clinical manifestations of halo nevus and vitiligo are white pigmented plaques, and the histopathological and ultrastructural changes are also similar, and it is often seen that when the halo nevus disappears, its white halo expands, and then new cases of vitiligo appear in other parts of the body, therefore, we believe that halo nevus is a type of vitiligo. The development site of vitiligo is not fixed, and it mostly occurs in the human face, neck, limbs, waist, abdomen and back and other parts of the body with rich sweat glands. At present, there is no specific method for the diagnosis of vitiligo, and the diagnosis is completely based on the doctor's experience.

Vitiligo has a high misdiagnosis rate, and the two diseases similar to vitiligo are anemia nevi and apigmented nevus.

Vitiligo is more common in the face, neck, limbs, waist, abdomen and back and other areas of the human body with rich sweat glands. Its development site is not fixed, such as the development of generalized large-scale vitiligo, which can lead to poor perspiration, ** cell metabolism disorders, and may also induce other diseases.

According to the experts of the Vitiligo Diagnosis and Treatment Center of Shanghai Guowen Hospital, there is no specific method for the diagnosis of vitiligo, and the diagnosis is completely based on the experience of doctors. Vitiligo has a high misdiagnosis rate, and the two diseases similar to vitiligo are anemia nevi and apigmented nevus.

Pigmentless nevi are congenital formations that are congenital due to the abnormal development of melanin in a certain area, but do not manifest immediately after birth, which is why it is easy to be confused with vitiligo. The growth of vitiligo is relatively random, and the area will vary with the four seasons, and it can be reduced after regularization. Once a non-pigmented nevus is formed, it is basically fixed in size, and its development speed and growth rate are directly proportional to the development of the body.

Vitiligo is distinct from the normal tissue, and the color of its periphery is significantly aggravated, and the boundary of the vitiligo will be clearer when pressed down vertically with a clean slide. Anemia nevus is just the opposite of vitiligo, anemia nevus is only localized hypopigmentation, not depigmentation, therefore, there is no obvious boundary between the lower pressure site and the normal **, the anemia nevus area has an obvious "dendritic texture", the anemia nevus has no tendency to expand, rub the skin lesion hard, the local area is not red, and the surrounding normal ** redness. When the slide is pressed down, the anemia will disappear.

Because the occurrence of vitiligo is affected by genetic, immune, mental and other factors, it causes local ** and melanin synthesis disorders in hair follicles.

What is the relationship between halo moles and vitiligo? This truth you should know.
