Pigmented nevi and unpigmented nevi, is it just a difference in color?

Of course not, in addition to this, the general non-pigmented nevus is innate, and it increases proportionally with the development of the body, and it is not possible to obtain pigment through the acquired **.

Not only the difference in color, but also the difference in the substance, and the pigmented nevus can cause other diseases, such as cancer.

It should not only be the difference in color, but also some words will cause us to get some cancer, or it may become a small tumor, which is very dangerous, so we must go to the hospital to check it out.

Almost everyone will have moles on their bodies, everyone's position is different, this is a very common phenomenon in life, there are many women who love beauty will point a little black mole under the nose or the corner of the eye to improve their beauty, there are many moles that are benign and malignant, generally appear in our body are benign, it is a melanocyte, usually this kind of benign mole is what we call black mole, if it is malignant, there will be a certain risk of cancer, this is what we call melanin, If it is severe, it may become melanoma, and most people are mainly benign in nature, and malignant moles like this are not very common, so let's take a look at the difference between black moles and melanin? <>

One, color

Ordinary black moles are black, brown or brown, generally dark tones, but melanin its color is colorful, it sometimes has some pink, blue, black, white this special color appears, if you find a blue mole on the body, then you should be vigilant, blue represents malignant melanin.

Second, the shape

The edges of ordinary moles are very distinct, and the borders are very smooth, and the melanin edges are untidy, very uneven, and uneven. From their shape, we can tell if it is a common mole or melanin. <>

Third, the growth rate

Black moles and melanin will grow, and will get bigger and bigger with age, but the difference between them is that the growth rate of black moles is very slow, basically there is no difference, and the human body can be proportional, for example, when I was a child, there was a very small mole in my palm, and when I grew up, the mole and my body were also in the original proportion, then this is normal melanin, but melanin, the growth rate will be very fast, it will suddenly become very large in a few months, In situations like this, we need to be vigilant. <>

The difference between black moles and melanin is still relatively large, we can judge it from the above 3 points, we don't need to pay too much attention to general black moles, but if in a short period of time, the melanin area expands very quickly, then we should be vigilant.

There is a big difference, because black moles will not affect our body, but melanin is different, it will have a great impact, and the damage is also great, and it will also appear that we are very dark, and the body will be unhealthy, but sunspots will not affect our body, and they are also innate, and they will not get bigger or smaller.

In terms of shape, it is not the same black mole, generally it is presented in a circle, but the shape of melanin is particularly strange, and it can not be seen on the edge at all, melanin is relatively rough, but the edge of the black stantia is particularly smooth, melanin will appear in any part of the body, from the pathological point of view, black mole is a normal phenomenon, and melanin is a disease.

Of course, there is a difference, black moles will not affect our body, melanin will have a lot of effects, will cause serious damage, and you should also pay attention to your physical condition, so as not to have a bad situation and sunspots will not spread, light melanin will, melanin will be more and more, so that our ** feeling darker and darker.

Of course, there is a difference, these two are different diseases, the depth under the ** is different, ordinary melanin can be cured by laser**, if it is a serious black mole, the root under the ** is particularly deep, and it takes a long time**.

There must be a difference between the two, if you have more melanin in your body, it will be duller, but if you have a black mole, it is just a mole on us.

There are often some moles on our body, some are normal moles that grow according to the condition of our growth, and there are many pigmented moles that can grow on any part of our body. Not only do they come in different colors and shapes, but they also differ in their classifications. Some moles will not affect our lives, but some moles will seriously endanger our health if they grow in the wrong places.

ClassificationFor pigmented nevi, it often appears in many different positions, and according to its histological classification, it can also be divided into many types. The most common is a junctional nevusThere are many people who are born with such moles, which are brown and dark brown in color at the beginning and may disappear with age。Mixed hemorrhoids are more convex than junctional nevus, and even some mixed hemorrhoids are black or red in color, which is more common between children and teenagers.

Then there are intradermal hemorrhoids, which often appear in the body of adults, and most of them are black or brown in color.

The impact of pigmented nevi is not too great for some pigmented nevi, if it does not develop to a more serious extent, we don't need to care about it, but some pigmented nevi are relatively unstable, and it is easy to undergo continuous changes in the process of their growth, and it is easy to have some harm to our human body. Some moles will have some mild pain reaction in the process of malignant transformation, and even have a sudden enlargement or darkening of color, if we find that it has an inflammatory reaction or bleeding, we need to check it.

There are many types of pigmented nevi, some of which are simply pigmented, but some of which are different colors due to the excessive production of melanocytes. The color of some pigmented nevi is more obvious, which is also related to the pigment produced by melanocytes, when we find that we have some pigmented nevi on our body, there is no need to be too nervous, we just need to observe for a period of time to decide whether it has an effect.

The color of these pigmented nevi is generally black, light brown, brown, and light-colored, and there are similar colors to **, as well as pink and purple-red.

Black, brown, red, flesh-colored, colorless, generally the formation of this kind of thing is related to genetics, and now it can also be removed, with lasers, and with medical aesthetic means.

Brown, dark brown, jet black, blue-black, normal skin tone, pale yellow, dark red, gray. These colors are all there.

There are many types of clinical presentations. The color is mostly dark brown or jet black, and there are colorless moles without color.

Hello, apigmented nevi occur at birth or shortly after birth in the baby and enlarge proportionally with age, the lesions tend to be distributed along the nerve segments, manifesting as localized or generalized hypochromic spots, the rash is very irregular at the edges, darkened without pigmentation, and is not as pronounced as vitiligo.

Vitiligo is a hyperpigmented disease. Begin to appear without conscious symptoms of local ** whitening, gradually expanding, the realm is clear, the surface is smooth, and there is no desquamation.

It is recommended that you go to the national formal professional vitiligo scientific research institution for testing and treatment in time, so as not to delay the condition and the best period, and strive for early detection, early, early!

In winter, the human activity is reduced and the pace of life is slowed down, which is conducive to freeing up time to concentrate**, and the patient is in a good mood and makes ** smoother; Vitiligo diagnosis is easy, difficult, and it is easy to encounter various problems in the process, and common problems include misdiagnosis and excessive. In the advanced stage of vitiligo, it is necessary to take systemic medication.

Early vitiligo should be distinguished from unpigmented nevi. Pigmentless nevus is congenital, it is a kind of ** vitiligo that is born soon after birth or birth, and vitiligo is an acquired disease, and it is generally not born with vitiligo.

In addition, although they are all white, the whiteness of vitiligo is more obvious, while the non-pigmented nevus is grayish-white and not so white; The edges of vitiligo are regular and rounded, and the edges of nonpigmented nevi are lace jagged; Vitiligo is diffuse and grows in other places, while unpigmented nevi only grow in their original area and generally do not spread over a large area except for the proportional enlargement of the body as the body develops.

If you can't tell which is vitiligo and which is unpigmented. You can go to the hospital for professional examination in time. For example, vitiligo is fluorescently white when detected with a Wood lamp, but there is no significant change in depigmentation of nonpigmented nevi.

Problem analysis: The most obvious feature of vitiligo is that it is easy to spread, and facial vitiligo is easy to be exposed to sunlight, so it is timely to control vitiligo, and then cooperate with daily life care.

You can definitely get it**. Use vitiligo Fuzheng powder and other medicines, as well as vitiligo pills. It can also be supplemented with immunomodulators**.

Problem analysis: There are many cases of vitiligo in children, 1. Psychological pressure. Children live in oppressive living conditions for a long time.

2. Children's immunity is low. Some children are born with or acquired poor immunity for some reason. 3. Lack of trace elements, caused by partial eating in most children 4. Serious pollution of the diet and living environment.

5. Chromosomal abnormalities. After the early symptoms of vitiligo appear, it is important to get tested as soon as possible**.

So exactly? For this reason, we asked experts from the Naval General Hospital to give a brief introduction to apigmented nevi, let's find out. Unpigmented nevi, also known as depigmented nevi, develop at birth or shortly after birth, and lesions tend to follow nerve segments.

Because non-pigmented nevi are very different from other black moles, red moles and pigmented nevi on the body, it is necessary to pay special attention to it. As for the question of what is a non-pigmented nevus, the experts of the General Administration pointed out that non-pigmented nevus is a rare, congenital, and localized hypopigmented spot. The disease** is unknown, but it is thought that the number of melanocytes in apigmented nevi is normal, and the onset may be related to abnormal melanosome synthesis and transport.

Depigmented nevi are congenital, non-progressive hypopigmented patches or patches that often develop at or shortly after birth and are relatively stable in size and distribution throughout life. In addition, apigmented nevi are inherited in an autosomal dominant manner, and may be a type of neural nevus, which develops after birth or shortly after birth, and continues to remain unchanged for life. Because apigmented nevus lesions are characterized by incomplete depigmented macules, they are polymorphic and may be mottled or threaded.

Xue Yanbin of Mr. Hai said that many people often confuse apigmented nevi with vitiligo, in fact, they are two completely different types of diseases, basically the difference between non-pigmented nevus and vitiligo is that vitiligo is not as obvious as non-pigmented nevus, and there is no pigment deepening phenomenon at its edges. Patients with apigmented nevi usually have other systemic diseases, mainly ectodermal lobe and central nervous system abnormalities. A distinction should be made at the time of diagnosis.

Hello, the unpigmented nevus** is unknown, but the method of unpigmented nevus** is indeed very simple. It is thought that the number of melanocytes in depigmented nevi is normal, and the onset of unpigmented nevi may be related to abnormal melanosome synthesis and transport. Apigmented nevi, also known as depigmented nevi, are congenital, non-progressive hypopigmented patches or patches that often occur at or shortly after birth, and are relatively stable in size and distribution throughout life.

Pigmented nevi are born cases that appear at birth of the fetus, some on the face, some on the body, some just a small patch, some a large patch, these early nevi are benign moles. It can grow slowly in the early stage, but the self-limitation of growth is difficult to conclusively, some patients begin to stabilize for a long time in childhood, and generally after puberty, but there are some people who still have a tendency to grow slowly until they are about 30 years old.

Pigmented nevi have no symptoms, and if they do, be alert to malignant transformation. Lesions appear as black, yellowish-brown or blue, flat or slightly raised spots or plaques; Still others are colorless, pigmented nevi. A very small number of pigmented nevi will undergo malignant changes and become malignant melanoma.

Hello, glad to answer for you.

If the boundary is blurred or the white spot is expanding towards normal, this situation can be preliminarily judged to be a symptom of vitiligo, and the specific condition still needs to be seen before it can be diagnosed.

It is recommended to go to a professional vitiligo hospital to find out the cause of the real melanin deficiency in order to treat the symptoms**. To achieve the goal of treating both the symptoms and the root causes.
