Understanding Nevi: The Medical Term for Moles

Nevi, the medical term for moles, are prevalent skin growths that most people have in varying numbers. These pigmented spots are typically harmless collections of colored cells that can appear as small brown, tan, or pink marks on the skin. While some individuals are born with moles (congenital nevi), most develop during childhood and adolescence (acquired nevi). Sun exposure can also lead to the formation of moles later in life.

The average person has between 10 and 40 nevi on their body. These common skin features come in various types, each with distinct characteristics. Understanding the different types of nevi and their potential implications for your health is crucial for maintaining good skin care practices.

Common Types of Nevi: From Congenital to Acquired

Congenital Nevus

A congenital nevus is present at birth and can vary in size, color, shape, and consistency. These moles are typically categorized as small, medium, or giant, with some covering large areas of the body. The presence of congenital nevi may require monitoring by a dermatologist, especially for larger ones.

Common Nevus

The most frequently encountered type is the common nevus. These moles are smooth, round, and uniform in color. They can be either flat or dome-shaped and may appear pink, tan, or brown. While some people are born with common nevi, most develop them during childhood.

Dysplastic Nevus

Also known as atypical moles, dysplastic nevi are benign but often resemble melanoma. They may feature different colors, appear asymmetrical, or have irregular borders. Individuals with dysplastic nevi have a higher risk of developing melanoma and should be vigilant about skin checks.

Unique Nevi Types: From Blue to Halo

Blue Nevus

A blue nevus is characterized by its distinctive blue coloration, ranging from blue-grey to blue-black. These moles can be congenital or acquired and are more commonly found in people of Asian descent. Blue nevi may appear flat or dome-shaped.

Miescher Nevus

Miescher nevi are brownish or skin-colored, dome-shaped moles that typically appear on the face or neck. They are firm, round, smooth, and may have hair growing from them. These moles are generally benign but should be monitored for any changes.

Unna Nevus

Similar to Miescher nevi, Unna nevi are soft, brownish moles that often resemble raspberries. They are commonly found on the trunk, arms, and neck. While generally harmless, any significant changes in appearance should be evaluated by a dermatologist.

Meyerson Nevus

Meyerson nevi are unique in that they are surrounded by a small ring of eczema-like rash. These moles can develop regardless of a person’s history with eczema and are more common in men, typically appearing around age 30.

Halo Nevus

A halo nevus is characterized by a white ring of unpigmented skin surrounding a mole. Over time, the central mole fades from brown to pink before disappearing entirely. It’s not uncommon for individuals to have multiple halo nevi at different stages of fading.

Potentially Concerning Nevi: When to Seek Professional Evaluation

Spitz Nevus

Spitz nevi are raised, pink, dome-shaped moles that typically appear before age 20. These moles can vary in color and may bleed or ooze, making them difficult to distinguish from melanoma. Due to their potentially concerning appearance, Spitz nevi should always be evaluated by a dermatologist.

Reed Nevus

Reed nevi are dark brown or black, raised, dome-shaped moles that primarily affect women. These moles can grow quickly and may be mistaken for melanoma. Also known as spindle cell nevi due to their microscopic appearance, Reed nevi require professional assessment to ensure they are benign.

Agminated Nevus

An agminated nevus refers to a cluster of similar moles located in one area of the body. These groups can vary in appearance and type, and while often benign, should be monitored for any changes or abnormal growth patterns.

Diagnosis and Biopsy: Determining the Nature of Nevi

If you’re uncertain about the type of nevus you have or notice any changes in existing moles, it’s crucial to consult a dermatologist. In cases where the nature of a mole is unclear or potentially concerning, a skin biopsy may be performed. This is the only definitive way to confirm or rule out skin cancer.

There are three main types of skin biopsies used for nevi:

• Shave biopsy: The top layers of skin are shaved off using a razor.
• Punch biopsy: A special punch tool removes a sample containing both top and deeper layers of skin.
• Excisional biopsy: The entire mole and some surrounding skin are removed using a scalpel.

The choice of biopsy method depends on the size, location, and suspected nature of the nevus. Your dermatologist will determine the most appropriate approach based on their clinical assessment.

Treatment Options for Nevi: When and How to Remove Moles

Most nevi are harmless and don’t require treatment. However, removal may be necessary or desired in certain situations. When should a nevus be removed? There are two main scenarios:

1. The mole is cancerous or has the potential to become cancerous.
2. The individual wishes to have a benign nevus removed for cosmetic reasons.

The removal process typically involves either a shave or excisional biopsy. For cancerous nevi, an excisional biopsy is often recommended to ensure complete removal of the affected tissue. It’s important to note that while some sources suggest at-home mole removal methods, these are generally not recommended due to the risk of infection, scarring, and missing potential skin cancers.

Skin Cancer Awareness: The Importance of Regular Self-Examinations

Early detection is key in the successful treatment of skin cancer. How can you protect yourself? Developing a habit of monthly skin self-examinations is crucial. During these checks, pay close attention to any changes in existing moles or the appearance of new growths.

What should you look for during a skin self-examination? The ABCDE rule is a helpful guide:

• Asymmetry: One half of the mole doesn’t match the other half.
• Border: The edges are irregular, ragged, or blurred.
• Color: The color is not uniform and may include shades of tan, brown, black, or even red, white, or blue.
• Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).
• Evolving: The mole changes in size, shape, or color over time.

Remember that skin cancer can develop in areas that are difficult to see on your own. Use a mirror or ask a friend or family member to help you examine hard-to-reach areas like your back, scalp, and behind your ears.

By familiarizing yourself with your skin and being proactive about regular self-examinations, you can significantly increase your chances of detecting potential skin cancers early. If you notice any suspicious changes or have concerns about a particular nevus, don’t hesitate to consult a dermatologist for a professional evaluation.

Advanced Imaging Techniques for Nevus Evaluation

In recent years, dermatologists have begun employing advanced imaging techniques to aid in the evaluation of nevi. These technologies provide more detailed information about moles, helping to distinguish between benign and potentially malignant growths.

Dermoscopy

Dermoscopy, also known as epiluminescence microscopy, is a non-invasive technique that uses a handheld device called a dermatoscope. This tool allows dermatologists to visualize structures within the epidermis and superficial dermis that are not visible to the naked eye. How does dermoscopy improve nevus evaluation? By magnifying and illuminating the skin, it reveals patterns and features that can help differentiate between benign nevi and early-stage melanomas.

Confocal Microscopy

Reflectance confocal microscopy (RCM) is another advanced imaging technique that provides high-resolution, in vivo images of the skin at a cellular level. This technology allows dermatologists to examine the architectural and cytological features of nevi without the need for a biopsy. What makes RCM particularly valuable? It can help reduce unnecessary biopsies of benign lesions while improving the detection of subtle melanomas.

Artificial Intelligence in Nevus Evaluation

The integration of artificial intelligence (AI) into dermatology has opened new avenues for nevus evaluation. AI algorithms, trained on vast datasets of skin lesion images, can assist dermatologists in identifying potentially malignant nevi. How accurate are these AI systems? Some studies have shown that AI can perform on par with expert dermatologists in distinguishing between benign and malignant skin lesions. However, it’s important to note that AI is currently used as a supportive tool and does not replace the expertise of trained dermatologists.

Genetic Factors Influencing Nevus Development

The development and characteristics of nevi are influenced by a combination of genetic and environmental factors. Understanding the genetic components can provide insights into an individual’s risk for certain types of nevi and related skin cancers.

BRAF Gene Mutations

Mutations in the BRAF gene have been identified in many common nevi and melanomas. What role does the BRAF gene play in nevus formation? This gene is involved in cell growth and division, and mutations can lead to uncontrolled cell proliferation. While most BRAF mutations in nevi are benign, they can occasionally contribute to the development of melanoma.

MC1R Gene Variants

Variants of the MC1R gene, which is involved in pigment production, are associated with an increased number of nevi and a higher risk of melanoma. How does MC1R affect skin phenotype? Certain variants of this gene are linked to red hair, fair skin, and freckles – traits that are also associated with increased sensitivity to UV radiation and a higher risk of skin cancer.

Familial Atypical Multiple Mole Melanoma (FAMMM) Syndrome

FAMMM syndrome is a hereditary condition characterized by the presence of multiple atypical nevi and an increased risk of melanoma. What genetic factors are associated with FAMMM? Mutations in the CDKN2A gene are often found in families with this syndrome. Individuals with FAMMM require close dermatological monitoring and may benefit from genetic counseling.

Understanding the genetic factors influencing nevus development can help healthcare providers assess an individual’s risk for certain types of nevi and related skin cancers. This knowledge can inform personalized screening and prevention strategies, ultimately improving patient outcomes in dermatological care.

Definition, Common Types, Photos, Diagnosis, and Treatment

What is a nevus?

Nevus (plural: nevi) is the medical term for a mole. Nevi are very common. Most people have between 10 and 40. Common nevi are harmless collections of colored cells. They typically appear as small brown, tan, or pink spots.

You can be born with moles or develop them later. Moles that you’re born with are known as congenital moles. However, most moles develop during childhood and adolescence. This is known as an acquired nevus. Moles can also develop later in life as a result of sun exposure.

There are many types of nevi. Some of them are harmless and others more serious. Read on to learn about the different types and how to know whether you should get one checked out by your doctor.

Congenital nevus

A congenital nevus is a mole that you’re born with. They’re generally categorized as being small, medium, or giant in size. They vary in color, shape, and consistency. Some congenital nevi cover large areas of your body.

Common nevus

A common nevus is a smooth, round mole that’s all one color. You can be born with them, but most people develop them later in childhood. Common nevi can be flat or dome-shaped and may appear pink, tan, or brown.

Dysplastic nevus

Dysplastic nevus is another name for an atypical mole. These moles are benign (noncancerous) but often resemble melanoma. They may feature different colors, appear asymmetrical, or have odd borders. People with dysplastic nevi are at higher risk of developing melanoma.

Blue nevus

A blue nevus is a blue-colored mole that can be congenital or acquired. A common blue nevus may appear flat or dome-shaped with a color ranging from blue-grey to blue-black. Blue nevi are commonly found in people of Asian descent.

Miescher nevus

A Miescher nevus is a brownish or skin-colored, dome-shaped mole that commonly appears on your face or neck. It’s typically firm, round, smooth, and may have hair coming out of it.

Unna nevus

Unna nevi are soft, brownish moles that resemble Miescher nevi. They’re typically located on your trunk, arms, and neck. An Unna nevus may resemble a raspberry.

Meyerson nevus

Meyerson nevi are moles surrounded by a small ring of eczema, which is an itchy, red rash. They can appear on your skin regardless of whether you have a history of eczema. Meyerson nevi affect men nearly three times as often as women. Most develop around age 30.

Halo nevus

A halo nevus is a mole with a white ring of unpigmented skin around it. Over time, the mole in the center begins to fade from brown to pink before disappearing entirely. It’s not uncommon for someone to have several halo nevi at different stages of fading.

Spitz nevus

A Spitz nevus is a raised, pink, dome-shaped mole that typically appears before age 20. Spitz nevi can have different color. They may also bleed or ooze. This can make them hard to distinguish from a melanoma.

Reed nevus

A Reed nevus is a dark brown or black, raised, dome-shaped mole that most often affects women. These moles can grow quickly and may be mistaken for melanoma. They’re sometimes called spindle cell nevi because of the way they appear under a microscope.

Agminated nevus

An agminated nevus refers to a cluster of similar moles located on one area of your body. These groups of similar-looking moles can vary in appearance and type.

If you’re unsure of what type of nevus you have, it’s best to have your doctor or dermatologist take a look.

If your nevus seems to be changing or your doctor isn’t sure what it is, they might perform a skin biopsy. This is the only way to confirm or rule out skin cancer.

There are a few ways to do this:

• Shave biopsy. Your doctor uses a razor to shave off a sample of the top layers of your skin.
• Punch biopsy. Your doctor uses a special punch tool to remove a sample of skin that contains both the top and deeper layers of skin.
• Excisional biopsy. Your doctor uses a scalpel to remove your entire mole and some of the other skin around it.

Most moles are harmless and don’t require treatment. However, if you have a mole that’s cancerous or could become cancerous, you’ll likely need to have it removed. You can also choose to have a benign nevus removed if you don’t like the way it looks.

Most nevi are removed with either a shave or excisional biopsy. Your doctor will likely recommend doing an excisional biopsy for cancerous nevi to make sure that they remove everything.

Learn more about removing moles, including when you can do it at home.

Skin cancer is easiest to treat when it’s caught early. It’s important to know what to look for so you can recognize the signs early on.

Try to get in the habit of examining your skin once a month. Keep in mind that skin cancer can develop in areas that you can’t easily see, so use a mirror or ask a friend to help you if you need to. You can also check out our guide to screening yourself for skin cancer.

Doctors have a developed a system known as the ABCDE method to help people identify signs of skin cancer. Here’s what to look for:

• A is for asymmetrical shape. Look out for moles that look different on each side.
• B is for border. Moles should have solid borders, not irregular or curvy borders.
• C is for color. Check for any moles that contain several colors or uneven and splotchy color. Also note if any have changed in color.
• D is for diameter. Keep an eye on moles that are larger than a pencil eraser.
• E is for evolving. Look for any changes in a mole’s size, color, shape, or height. Also watch for any new symptoms, such as bleeding or itchiness.

You can keep track of your existing moles and changes by using this body map and chart from the American Academy of Dermatology.

Nevi come in many shapes and sizes but most of them are harmless. Still, it’s important to keep an eye on your moles because changes could indicate a problem. If you’re worried about one or more of your moles, don’t hesitate to get it checked out by your doctor. They can do a biopsy to rule out skin cancer.

Nevus: types, causes, symptoms, diagnosis

Few people know, but the largest human organ is the skin. Various formations appear and disappear on its surface during life. The most common are nevi. Among ordinary people, such benign formations are called ordinary moles.

What are nevi

They are a formation consisting of melanocytes. The surface of the mole is smooth and dark in color. On the body of an average person, you can count up to 40 such formations. Some moles are on the baby’s body immediately after birth. Others are formed during maturation. Nevuses can change their appearance and color. Most changes occur during adolescence during puberty. Also, rebirth in a nevus can begin when a person is in direct sunlight for a long time. Ultraviolet radiation in large quantities negatively affects the skin. According to statistics, the more time a person spends in the sun, the more moles on his body.

The changes concern not only the color, but also the appearance. An ordinary mole can become flabby and soft, or, on the contrary, develop into a dense and colorless formation. There are a large number of different types of nevi. The main danger of such formations, when exposed to certain factors, they can degenerate into malignant ones. Of particular danger are complex moles, as well as large formations. They must be constantly monitored by the attending physician, so it will be possible to prevent a dangerous transformation.

Varieties of nevi

There are moles on the body of every person. Most of the time they don’t pose any danger. If the quantity exceeds 50 pieces, it is advisable to visit a doctor. Such patients are at risk for developing melanoma. Particularly alarming should be asymmetric formations with an uneven surface, which have a non-standard color, more than 6 mm in diameter, began to form on the body already in adulthood.

Congenital

The category includes formations with which a person is immediately born. Congenital nevi vary in shape, color and size. In some cases, a mole can occupy a large part of the child’s body. Such neoplasms cause concern, as they often degenerate into cancerous tumors.

Ordinary

The category of ordinary moles consists of formations that are symmetrical in shape, uniform in color and have a smooth surface. Most often the color is brown or pinkish. There are no foreign inclusions on the surface. Also, such moles can be dome-shaped.

Atypical

Moles with irregular size and appearance. There are few of them on the body, many times less than ordinary moles. The main danger of such neoplasms, under certain factors, they can degenerate into melanoma. Another feature of such formations is their uneven color, uneven edges, and the nevus itself is asymmetric. It is important for people with atypical moles to control their number on the body; the more formations, the higher the risk of melanoma. It requires constant supervision by the attending physician and the passage of the necessary studies.

Blue

Neoplasms are divided into two categories – they can appear on the body already in the womb or develop during the life of a person. They got their name from their blue color. But this category also includes nevi, the color of which varies from light gray to black. Most often, formations characteristic of the Mongoloid skin, in other races they develop in extreme cases.

Misher’s nevi

Brown or flesh-colored lesions. The most common place for the appearance of moles in the neck and on the face. The surface is hard, domed, but even, without foreign inclusions. Hair often grows on a nevus.

Unna’s nevi

They look like moles from the previous description. The features include the appearance they resemble raspberries. The color of the neoplasm is brown.

Meyerson’s nevus

It is not difficult to identify the problem around such a mole, a rash with red papules begins to develop and spread. In some patients, eczema in the area is not recorded. Another feature of Meyerson’s nevi predominantly develops in men over the age of 30 years. Women are much less likely to have this problem.

Halo nevi

They got their name from the atmospheric phenomenon of the same name. A pale whitish ring begins to appear and develop around the mole. Until the end of life, such education does not linger, even if nothing is done with it. First, the ring changes its color to pink, and then disappears. In some cases, new halo may appear around the neoplasm throughout the patient’s life.

Spitz nevi

Moles are slightly raised above the skin and have a domed shape. The very formation of a pinkish hue, it refers to acquired and appears on the skin in patients at a young age. Coloring may be different. The surface of the nevus is often damaged and begins to bleed. As a result, doctors often confuse such moles with malignant ones, referring the patient for a histological examination.

Reed’s nevi

The color of the formations varies, they can be black or dark brown (closer to black). Mostly develop in women. The peculiarity of the neoplasm, it very quickly increases in size, which causes concern among doctors. In fact, such moles are mostly harmless and rarely develop into cancerous ones.

Agminated

They are several moles at once, which are concentrated on a small area of ​​the skin. The peculiarity of education is that all nevi are not the same among themselves. Some may be more, some less. Also among the flat formations dome-shaped, etc. may appear.

Only the main types of moles are listed above. In fact, there are a huge number of such neoplasms on the skin. To determine which type this or that mole on the body of a patient who seeks medical help belongs to, doctors perform dermatoscopy.

Papillomatous nevus

A large number of neoplasms occur on the human body. Not all of them are moles. So, warts, warts, papillomas and other formations may appear. When making a final diagnosis, the whole difficulty lies in the fact that the listed types of neoplasms often do not differ in appearance from ordinary nevi. The most problematic is considered to be papillomatous nevus. In appearance, it is no different from the usual papilloma caused by HPV. But when conducting research, it is revealed that this is a bumpy mole of a convex type. The mole is benign, there is no risk of degeneration into cancer. The surface has a flesh, brownish or light brown tint. Dark moles of this type are extremely rare.

A characteristic feature of these moles is the presence of hair on the surface. They mainly appear on the head or neck, they can develop in other parts of the body, but in very extreme cases.

The appearance is not tied to a specific age period. They develop in both teenagers and the elderly. A mole grows over time, sometimes it increases in size so much that it begins to cause discomfort to the wearer. If the nevus is located on the head, it is easy to damage it while combing the hair. This leads to the onset of inflammatory processes that affect nearby tissues.

Nevus is not dangerous, its removal is mainly carried out for cosmetic purposes only. Moles on the face, which are visible to everyone around, bring the greatest discomfort to people. Before deciding on the procedure for excising a neoplasm, it is important to consult a dermatologist. Only after all the studies have been carried out, a specific type of nevus will be established, and the likelihood of a degeneration of the problem will be assessed. It is almost impossible to independently determine what exactly has appeared on your body.

Permanent damage to the surface of the nevus may also be an indication for removal. Most often, several methods are used to combat education at once:

• Treatment of the site with a laser;
• Freezing and subsequent destruction;
• Radio wave exposure;
• By electric current;
• Surgical intervention.

If the formation is manifested on the face, laser therapy is most often chosen.

Intradermal nevus

A variety of common nevi that have a domed shape. Such moles rarely appear in childhood, but they are extremely common in the adult population. Up to ten such formations on the body can simultaneously appear on the body. Such neoplasms got their name due to the fact that they are under the upper layer of the epidermis. Often such moles are difficult to notice, they almost do not stand out above the surface of the body, and their shade is close to the surrounding tissues.

Nevus can appear almost anywhere. Favorite places of neoplasm are the upper part of the arms, eyelids, neck, face, etc. The maximum size of moles is up to 1 centimeter. When they appear in childhood, the nevi are almost invisible, but with age they begin to darken, often acquire a convex shape. If the mole persists further, then after 70 years it will gradually begin to discolor.

There are several reasons why intradermal nevi can form on the human body:

1. Hereditary factors . If there are more than 50 ordinary moles on the body of the baby’s parents, then the child’s nevi will also be multiple.
2. Sun exposure . Ultraviolet radiation negatively affects the skin, causing damage to it. Moles often appear on the spot. At risk are people with too fair skin.
3. Decreased immunity . Most often, nevi begin to form against the background of reduced immunity, including after taking drugs that suppress the immune system.

Even ordinary moles that are symmetrical and do not increase in size are important to keep under control. It is better to arrange checks with a dermatologist at least once a year, so it will be possible to identify the problem at an early stage of its occurrence. It is worth planning a trip to a specialist outside the schedule if the mole began to grow, changed its shape, acquired a different shade, and began to bleed.

A dermatologist may prescribe a procedure to excise a mole if it causes cosmetic discomfort to the wearer, if there is a risk of the neoplasm degenerate into melanoma, if the surface of the nevus is constantly damaged during the day.

Epidermal nevus

As the name implies, this category includes moles, which are formed from the upper cells of the epidermis. Basically, there are neoplasms on the child’s body after birth, the vast majority of such nevi also appear in the first year of the baby’s life. A distinctive feature of a neoplasm is that it remains unchanged in shape and size throughout a person’s life.

Epidermal nevi are divided into several types depending on the cells that make up them. The most unpredictable is considered to be formations, which include not only keratinocytes, but also sweat gland cells. The formations have a yellow-orange hue, in 25% of cases they degenerate into malignant tumors.

Pigmented moles

Most species are light pink to black in color. There are several exceptions to the rule. So, sometimes a nevus may not have pigment. To identify such moles, they are simply a whitish or lightish spot with fuzzy borders and an irregular shape. Moles without pigment can only appear on the body of Europeans.

Moles without pigment are characterized by a small size up to 2 centimeters. Basically, only the cosmetic side of the issue becomes an indication for removal. If a person often tans, the nevus remains light in color, as a result, it stands out very much on the skin and attracts attention.

Borderline nevus

The formations got their name due to the fact that they often develop into malignant formations. It is important to constantly monitor such moles and consult a dermatologist if any changes are found.

Such moles are hidden under the horny layer of the skin, they have a uniform brown color, clear boundaries. The following factors should cause concern in the patient and provoke an appeal to a dermatologist:

• the mole begins to increase in size;
• changes its color, darkens or brightens;
• pigment spots of various types began to appear around the adjacent area;
• the mole has become dense, standing out above the surface of the skin;
• there was pain in the mole, the surface itches a lot.

How to deal with huge nevi

The vast majority of nevi are small formations on the skin with a diameter of several millimeters, which are almost invisible to the naked eye. Exceptions are formations that exceed 20 centimeters in diameter. They are classified as huge. A mole can cover most of the arms, legs, back, etc. Such moles can appear on the body of representatives of any race. They develop in almost 2% of the population of our planet. The main danger of large nevi is that they often degenerate into malignant ones. Formations that appear in the region of the spinal column are considered to be extremely unstable. Moles should cause concern, which continue to rapidly increase in size, as well as change their color.

The most unpleasant huge nevi on the body of newborns. Since the child grows over time, it seems to parents that the mole decreases in size, in fact, it continues to grow as well, almost keeping up with the whole body.

In 30% of cases, these nevi become melanoma. They must be under the supervision of a doctor. Rebirth can occur at any age. Removal of giant nevi is shown. The most commonly used method is surgical excision. If the mole is located in a hard-to-reach place, alternative methods of treatment may be offered to the patient. Removal is also possible with the help of laser therapy.

Nevuses on the head

Such formations are most often removed for cosmetic reasons. If the mole is on the surface of the body, no matter what size it is, it can almost always be hidden under clothing. Nevuses on the head cannot be hidden. Some patients believe that a mole emphasizes their individuality, others are sure that such an education only spoils their beauty. As a result, patients often seek the removal of even those nevi that will never become malignant.

Often, not only moles on the head are removed, but also neoplasms on the neck. The main danger of such moles is that they often rub against the surface of clothing, as a result, they are damaged, which increases the risk of rebirth. On the head, nevi also occur in the area of ​​\u200b\u200bthe hair. They are almost invisible to the naked eye, often felt by the patient when washing his hair and other procedures. The main danger of neoplasms is that they are easily damaged during the banal combing of hair. On the head in the area of ​​the hairline, nevi also often appear, including cells of the sebaceous glands. They are characterized by the shape of a wart with the absence of hair on the surface, as well as an irregular shape. Human papillomaviruses, as well as hereditary factors, can cause the appearance.

Most moles on the head appear at birth. Education is examined, studies are done to make a final diagnosis. In childhood, neoplasms are rarely removed, since they are not subject to rebirth during this period. It occurs most often during puberty. The removal method is selected depending on the size of the formation. If the nevus is small, it can be removed with the help of laser therapy, to combat large formations, surgery will be required.

It is important to remember that at the moment there is no magic pill that could remove all dangerous moles that can become malignant from a person’s skin. It is important to monitor the condition of the nevi and pay attention to any changes.

Moles are successfully removed. It all depends on the size, qualifications of the medical specialist, as well as the location of the nevus.

Removal of nevi in ​​”Laser Plus”

Moles have long ceased to be considered a serious problem. Such formations on the skin are easily removed in beauty salons. The cost of the procedure is low. It is important to remember that only an equipped clinic with qualified personnel can guarantee a good result during removal.

Before starting the intervention, it is important to carry out a comprehensive diagnosis of the mole. It is impossible to simply look at the formation on the skin and make a diagnosis. There are a large number of nevi that are similar in appearance, but have a completely different structure.

Nevus – a benign skin neoplasm consisting of pigmented cells. It can be congenital or appear during life. Looks like a spot or a bulging pea. The color varies from flesh to dark brown. When exposed to ultraviolet radiation and other adverse conditions, it can degenerate into a malignant tumor.

In simple terms, a nevus is a mole. Every person has such formations and often does not manifest themselves in any way. But sometimes they need to be removed – if they spoil the appearance, or there is a risk of degeneration into cancer.

In the clinic of Bilyak, any skin neoplasms are easily and painlessly removed. Our doctors select the removal method individually for each patient. They remove the mole without leaving marks on the skin.

Causes of appearance

Skin nevus can be congenital or acquired. The first are laid in the process of intrauterine development. The process of migration of pigment cells is disrupted, as a result, they accumulate in the skin. A child can be born already with nevi, or they appear in the first months of life. Usually, congenital moles are inherited – if the parents have a lot of them, then the child will also have them.

Acquired nevus on the skin appears when:

• Hormonal changes – during puberty, pregnancy, age-related changes in the body. Endocrine pathologies can cause active growth of moles, a change in their shape.
• Exposure to ultraviolet radiation – in people who like to sunbathe in the sun or in a solarium, insolation of the skin occurs, due to which melanin is actively produced. This provokes the formation of moles.
• X-ray and radiation – under the influence of active particles, pigmented cells move to the epidermis, forming a dermal nevus.
• Frequent skin infections – rash, irritation, pimples cause inflammatory changes in tissues.

Classification of nevi

Neoplasms of this type are classified according to several parameters. Localization:

1. Intradermal nevus is an accumulation of pigment cells formed in the deep layers of the dermis. This type is the most common. It rises above the skin and resembles a dome in shape, sometimes it has a hairline on top. It can be located both on a wide base and on a leg. This type of neoplasm is also called intradermal nevus. It is usually benign, but can be easily injured. Because of this, degeneration into a cancerous tumor is possible.
2. Epidermal nevus – accumulation of cells in the upper skin layer (epidermis). These formations are most often flat, but may rise slightly above the surface of the skin. As a rule, they do not pose a danger.
3. Mixed – pigment cells accumulate at the border of the dermis and epidermis. Most often, these are flat brown spots that do not rise above the skin.

By size:

• small – up to 1.5 mm in diameter;
• medium – with a diameter of 1.5-10 mm;
• large – over 10 mm;
• giant – occupy a large area of ​​​​the body.

Symptoms

Moles can be recognized by their appearance. It differs depending on its type. For example, an intradermal nevus usually has the shape of a pea that rises above the skin. It can grow into the skin, or be located on the leg. The color varies from flesh to black.

Linear epidermal nevus looks like a dot or spot, the color varies from brown to black. Usually it is on the same level with the skin, but sometimes it can rise above it.

Usually these growths do not cause discomfort and do not show any symptoms other than visual. But sometimes they can be accidentally injured, rubbed with clothes, damaged with sharp objects. In this case, they can hurt and bleed, interfere with the person.

Nevus most commonly occurs on the head, neck, and other exposed areas of the body. Often they form on the back, chest and limbs. They can also be localized on the mucous membranes.

Possible complications

In most cases, these skin lesions are harmless. But under the influence of sunlight, they can degenerate into a malignant tumor – melanoma. The intradermal melanocytic nevus is most at risk.

Diagnostics

To understand how dangerous education is, you need to contact a dermatologist. He will conduct a dermatoscopy – an examination with a special device with multiple magnification. At the same time, color, uniformity of edges, shape, size are evaluated. Based on these data, the doctor calculates the dermatological index of the tumor.

It is recommended to have this examination every year. This allows you to study them in dynamics. The doctor draws up a map of moles and notes if there are changes in shape, size, color.

If the surface of the mole is cracked and bleeding, a swab is taken. It is sent for histological examination and carefully examined with a microscope. This allows you to understand whether there is a degeneration into a malignant process.

Treatment

Most often, epidermal and intradermal skin nevus does not require treatment. If it does not bother a person, it is better not to touch it. Some people themselves want to remove them for cosmetic reasons. But with this you need to be careful. Before removal, you should consult a doctor.

Today, sparing cosmetic methods are used to remove the nevus without pain and a trace.
