What are the symptoms of pigmented nevi?

Located in some parts of **, it is also a synthetic melanin, and it will be secreted frequently, and it can also protect **, and it will not cause complications, etc.

In general, moles are larger and darker in color, and they may itch, ulcerate, and if the mole is severe, they may bleed. Erythema can also occur. Therefore, when we have these symptoms, we must go to the doctor in time and do not bring unnecessary trouble to ourselves.

Pigmented nevi** ulcers, the surface of the pigmented nevus will feel moist, there will be the formation of scabs, there will also be **unsmooth, spots, pimples, nodules, etc.

In general, pigmented nevi do not have any symptoms, but when pigmented nevi appear, they will have symptoms of itching, erythema, bleeding, ulceration, and pain.

First of all, there will be a dark spot on the face, and with age, the dark spot is getting bigger and bigger, and it can be purple or blue, if the sun is exposed, the area will increase rapidly, and the laser method should be taken at this time.

Pigmented nevi are similar to the moles that grow on everyone's body, and pigmented nevi are common to everyone, and they are characterized by black or brown spots one by one. Generally speaking, the presence of pigmented nevi does not affect people's health, but it will affect the appearance. In particular, if a pigmented mole grows on the face, it will always make the face look dirty, and women with pigmented nevi will also be particularly troubled.

According to statistical surveys, people with fair skin have a higher chance of developing pigmented moles than people with dark skin.

Pigmented nevi need to be observedOf course, there are some black people who have pigmented nevi that are not particularly obvious, because many times pigmented nevi are brown and close to the color of **. Although pigmented nevi do not affect anything, it is important to always observe the shape of pigmented nevi because pigmented nevi are very likely to cause lesions. If you notice that the surface of the pigmented nevus is ulcerated and painful, you need to pay attention to it.

Seek medical attention in a timely manner, normal pigmented nevi will feel uneven to the touch, and there will be no pain when pressed by hand, so there are other conditions that indicate pigmented nevus lesions. It is recommended that you go to a regular tertiary hospital to find a professional doctor to diagnose yourself, and when the pigmented nevus is not particularly serious, the doctor will judge what is happening according to the naked eye. There are also some special pigmented nevi, which need to be examined by medical imaging to determine the extent of the lesion.

Maintain a healthy lifestyleIn order to prevent the development of pigmented nevi, it is necessary to maintain good lifestyle, work and rest habits, and dietary habits in daily life. Although young people especially like to eat roadside stalls, eat fried chicken, fried skewers, spicy and greasy food, but it is recommended to reduce the intake of these junk foods, which is not good for the development of pigmented nevi, only a healthy diet and regular work and rest are good for our body.

Usually flat on the surface, some junctional nevi develop with the body and may transform into mixed nevi and intradermal nevi, that is, pigmented nevi can grow from small spots to large and raised.

Its morphology is flat, and it can also be present as it is, and it can also be noduloid. Its color is black, yellowish-brown, purple. The big ones are as big as peanuts, and the big ones are as big as pinheads or mung beans. It generally grows anywhere on the body.

Pigmented nevi are very stable and do not cause complications. Pigmented nevi are very dark in color and vary in shape, sometimes flattened, sometimes raised, some tumor-like and some like scabs.

It is characterized by obvious differences. Comparisons vary in size. The shapes are also different. It also shows different colors. At the same time, there is a clear diversity. The surface is also relatively smooth.

Intradermal nevi, junctional nevi, compound nevi, these are the most common pigmented nevi, but generally do not affect the health of the body, but if it is cancerous, it is necessary to go to the hospital for **.

Pigmented nevi are generally divided into three types, namely junctional nevi, intradermal nevus, and mixed nevus, and the manifestations of these pigmented nevi are different.

Most will be divided into three types. The first type is intradermal nevus, the second is junctional nevus, and the third is compound nevus.

It can be divided into two categories, one is congenital and the other is acquired, and sometimes we can avoid the appearance of this pigmentation.

It is said that pigmented nevi is not harmful, and the harm here means that it has no impact on health, and the impact of pigmented nevus on most people is to affect the image. But many people still don't know that these pigmented nevi that everyone has will also have the possibility of malignant transformationLet's take a look at the introduction below!

Benign pigmented nevi are usually less than 6 mm in diameter, and if they enlarge suddenly or persistently, they may be a sign of malignant transformation. 2. Shape change: benign moles are round, with a clear boundary between them and normal **, with regular edges, flat or slightly raised.

In malignant transformation, the edges are irregular, may be serrated or other shapes, and the pigment often spreads and extends and is normal around it**. At the time of malignant transformation, the shape is no longer round, but becomes asymmetrical and irregular. 3. Color change:

Benign pigmented nevi have a uniform color, dark brown or black, and no other variegation. In addition to dark brown and black, red, pink, white, and blue can appear, and this color can spread from the edge of the mole to the surrounding area normally**. Fourth, surface changes:

The surface of benign pigmented nevus is smooth and flat, and there are no other pathological phenomena, such as desquamation, erosion, exudate, crust, ulceration, bleeding, etc., which are often signs of malignant transformation. 5. Bulge changes: benign nevi are generally flat or slightly raised, such as sudden and obvious bulge**, especially on the original flat pigmented nevus, which is often a sign of malignant transformation.

6. Surrounding ** changes: When the pigmented nevus is in a benign state, the surrounding ** is completely normal, such as flushing and swelling, especially when there is a small and fast "satellite pigment fast" around the mole, it should be considered as the beginning of malignant transformation. 7. Sensory changes:

Benign pigmented nevi feel the same as normal**, and if abnormal sensations occur, such as itching, tenderness, and pain, you should pay close attention to malignant tendencies. 8. Change in hardness: benign moles have uniform hardness and soft texture, such as suddenly becoming "soft" or "brittle" in texture, most of them are signs of malignant transformation.

In particular, people over the age of 40 who have benign pigmented nevi should pay more attention to the changes of moles that grow on the back, waist, buttocks and other parts of the body. If you have any other questions, please click on our **experts to consult!

Because pigmented nevi are easily confused with some ** malignant tumors, even some pigmented nevi are benign tumors belonging to the melanocytic system and are composed of nevus cells. To put it simply, it is divided into epidermis and dermis from the surface to the deep layer. A junctional nevus is called a junctional nevus when the nevus cells are located at the junction of the lower epidermis and the dermis; When the nevus cells are located within the dermis, it is called an intradermal nevus; Nevus cells are either located in the epidermis or in the upper dermis, which is called a mixed nevus.

When a pigmented nevus changes to cancer, there are several early signs.

1. Pigmented nevi generally appear from birth to 30 years old. The appearance of new pigmented nevi after the age of 30 should raise suspicion.

2. Pigmented nevi are infected, and the volume or area increases rapidly and significantly.

3. Pigmented nevi often bleed, and scabs formed or ulcers appeared on the surface.

Fourth, the pigmented nevus is locally painful, burning or persistent itching.

5. There is inflammatory redness around the pigmented nevus, or punctate satellite nevi around it.

6. The original hair on the pigmented nevus suddenly falls off, and the color deepens rapidly, turns black, or there is an inflammatory redness around it.

These symptoms are some common symptoms before the cancerous transformation of pigmented nevi, if this symptom appears, it is necessary to seek medical attention in time to avoid delaying the best opportunity. In fact, the vast majority of pigmented nevi are benign and have no effect on physical health. Cancerous pigmented nevi are among the few pigmented nevi.
