What is the relationship between halo moles and vitiligo?

What is the relationship between halo moles and vitiligo? A halo mole is a type of vitiligo.

Halo nevi are also known as centrifugal acquired leukoplakia or acquired distal leukoplakia. This type of vitiligo usually refers to localized hypopigmentation surrounding a pigmented nevus, which may later fade and the lesions continue to develop. This type is mostly found on the face, chest and back, the original or still retains black and red moles or abnormal bulges in the middle of the lesions, this type of leukoplakia has a clear boundary, the middle bulge can be large or small, some of the bulges have the pigment loss first, and then the leukoplakia expands, and some have the leukoplakia area first, and then the bulge disappears or still exists, such patients mostly have palpitation and fatigue.

The so-called halo nevus vitiligo is the spread of vitiligo lesions around the nevus, forming perinevus vitiligo. It is characterized by the fact that the perinevus leukoplakia is not centered on the nevus, and the shape is irregular, with clear borders and pigmentation bands. The other kind of halo nevus, that is, acquired centrifugal leukoplakia, is characterized by white spots centered on black nevi, mostly round, and its surrounding non-pigmented band is distinguished from halo nevus vitiligo.

Some patients have halo nevus and halo nevus vitiligo at the same time, the black nevus and halo nevus of the two can sometimes become lighter or even disappear, and due to the white halo of the halo and the depigmentation of vitiligo, the clinical manifestations of both are white depigmented plaques, and the changes in histopathology and ultrastructure are similar.

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 sweat glands of the human face, neck, limbs, waist, abdomen and back.

Abundant parts. At present, there is no specific method for the diagnosis of vitiligo, and the diagnosis is completely based on the doctor's experience. White.

The misdiagnosis rate of leprosy is high, and the two diseases similar to vitiligo are anemia nevi and apigmented nevi.

Vitiligo is more common in the face, neck, limbs, waist, abdomen and back and other areas of the human body with rich sweat glands. That.

The site of development is not fixed, such as the development of generalized large-scale vitiligo, which can lead to poor perspiration, ** cell generation.

Xie disorder 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 it is completely dependent on medical treatment.

Empirically confirmed by birth. Vitiligo has a high misdiagnosis rate, and the two diseases similar to vitiligo are anemia and nevus.

No pigmented nevi. An unpigmented nevus is a condition in which melanin is not properly developed and is born but is not born with a certain area.

It can be immediately manifested, which is why it is easy to confuse 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. And unpigmented nevi, once formed, are large.

The small is basically fixed, and its growth rate and growth rate are directly proportional to the development of the body.

Vitiligo is distinct from normal ** tissues, and the color of its periphery ** is significantly aggravated, so use a clean slide.

When pressed vertically downward, the white patches are more defined. Anemia nevi 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 **, anemia.

The mole area has a distinct "dendritic texture", the anemia nevus has no tendency to expand, rub the skin lesion vigorously, and there is no redness locally, while the surrounding area is normal**red. When the slide is pressed down, the anemia will disappear.

Because the occurrence of vitiligo is affected by genetic, immune, psychiatric and other factors, it causes local ** and hair follicles.

There is a disorder in the synthesis of melanin.

There is a certain relationship, and it is recommended to follow the doctor's advice**. It is usually caused by many triggers, including low mood, emotional agitation, lack of sleep, etc. Many people have vitiligo and cannot understand it correctly, and often have pessimism, depression, nervousness, depression, fear, frustration and other emotions, some even have restless sleep, and some want to find a short-term view

Hello, halo nevus is a centrifugal vitiligo, also known as halo nevus vitiligo. There will be white spots around the disappearance of halo moles, and there is a certain chance of inducing vitiligo in the later stage, so you must not ignore the appearance of white spots and go to the hospital as soon as possible**.

It is a type of vitiligo and sometimes occurs at the same time as vitiligo. It is more common on the trunk and is a round and oval hypopigmented patch centered on a mottled nevus. **Moles may fade and leave small papules with reddish papules or flatten, and eventually resolve.

Subsequently, some of the white spots also subsided, and occasionally the white spots persisted for a long time or continued to expand.

The cause of vitiligo is mainly due to human blood heat or body heat, external wind, dampness, rheumatism invasion of the skin, resulting in local qi and blood imbalance, meridian blockage, blood does not honor the skin, qi stagnation, and pores are occluded, thus forming vitiligo.
