Brown moles appeared on the body. What causes moles to appear - the causes of their occurrence in humans. Why moles appear on the body, video

Most people have dark moles. Rarely does anyone pay attention to them close attention. The only cause of concern is the changes occurring in birthmarks, which can lead to the degeneration of a benign mole into a malignant one. In order to prevent and notice such processes in time, you need to be well informed about why moles appear, about the signs of their degeneration, preventive measures. This article is devoted to these issues.

Causes of moles

the mole begins to increase in size (this happens gradually over several months, maybe even years);
the nevus changed its rounded shape, became asymmetrical, with uneven, jagged edges;
the formation began to crust over light yellow color, after which disappears appears serous fluid, or blood;
bleeding of a mole for no specific reason (remember, if the wound does not heal within 2-3 weeks, then this is a reason to consult a doctor);
color change birthmark, which takes on a bright shade of burgundy interspersed with black;
soreness, burning sensation, itching in the area of the nevus.

It is also worth noting that hair, which previously appeared regularly, stops growing from a degenerated mole. Therefore, if a black mole appears, which is characterized by such dynamics, then you need to immediately contact an oncologist or dermatologist in order to exclude the possibility of developing cancer.

Diagnosis of a pigmented spot

To diagnose the disease, the doctor will conduct a thorough examination, possibly dermatoscopy, which will help increase the size of the birthmark being examined. Also, if the doctor has any concerns, they will take additional tests:

histological, when a piece of tissue is taken from the neoplasm and can be further examined for the presence of dividing cancer cells. However, for malignant melanoma this analysis is not performed so as not to aggravate the situation;
a cytological impression of a neoplasm, in which the doctor does not touch the mole, but only makes an imprint of it.

Only after these tests can the type of cancer and the degree of its development be accurately determined. IN currently Such skin diseases can be successfully treated if they are identified in time.

Treatment methods for pigmented spots

However, it is better to prevent a bad scenario from developing. Therefore, if a convex black mole has formed on the skin of an adult or child, groin area, under the breasts, under the arms or in another area where it is easily injured, in which case the doctor may recommend its removal. On this moment, there are many safe procedures, with the help of which you can quickly and painlessly remove disturbing tumors that are often injured. For these purposes the following are used:

laser therapy– the process of removing a mole using laser light, which destroys neoplasm cells;
cryodestruction– freezing the nevus with liquid nitrogen, which leads to tissue necrosis and, at the same time, separation of the growth from the skin;
electrocoagulation - the process of cauterizing a mole with an alternating electric current (after this procedure a small scar may remain);
radio wave surgery – removal of a convex nevus with a radio wave knife;
surgical an operation in which tumor tissue is excised.

The above procedures are very effective and widely used in medical practice. Remember, if an unpleasant black mole appears, it must be removed by a qualified specialist. It is absolutely impossible to get rid of a nevus on your own, at home, since trauma to the birthmark can lead to its degeneration.

However, in the best possible way Avoiding malignancy (degeneration of nevi) is the prevention of skin cancer. You should always remember these safety rules:

do not visit solariums or at least limit the number of visits;
When tanning, always use sunscreen;
wear in summer Sunglasses, hat, clothes that cover the areas of greatest localization of moles;
limit exposure to the sun in the hot season from 11 to 16 hours of the day;
clothing should be made from natural materials: linen, cotton, silk;
during the reception water procedures be very careful not to damage prominent nevi;
regularly examine your body skin, pay attention to even minor changes that occur with growths on the skin.

Most importantly, don't be afraid to see a doctor. Get a dermatological examination regularly and follow all doctor's instructions. If you follow these simple tips, then no disease will be terrible.

Where do new moles come from?

There is nothing scary or frightening about the appearance of moles, but there are many mysteries. For example, not everyone knows why moles appear, where they originate and how they develop. In fact, this is very interesting, just like the fact that moles can be completely different; in fact, there are no exactly identical nevi on the body - this is a fact! So, moles first appear in the first or second year of life, although some people are born with birthmarks that are visible immediately or appear by 1-2 months. Moles are most often divided into:

Vascular and non-vascular,
Melanoma-hazardous and non-hazardous.

With age, the number and visibility of moles increases, although many have long believed that moles are spots with which they were born. The main rash of moles appears during hormonal imbalances such as pregnancy, stress, illness and, of course, puberty in teenagers.

Vascular moles are a collection of small blood vessels, hence the color of moles, which can be either light pink or bright red. Moles of this type can be either flat or convex, but they have one feature: these are benign neoplasms that do not develop into malignant tumors, i.e. are melanoma-free.

This cannot be said so easily and beautifully about non-vascular (ordinary) moles. They are easy to recognize - they can be small or large, convex or flat, but they can be identified by their color - from light brown to black. Such moles are melanoma-dangerous, although the degeneration of the mole into malignant tumor is rare. In fact, non-vascular moles are the cells of our skin, where a lot of pigment is accumulated; they are only formed due to melanin. Birthmarks that appear immediately after the birth of a child are considered congenital skin defects, the rest are acquired tumors.

So, where moles come from, as you yourself understand, directly depends on their type. Children often experience hemangiomas, which need to be treated so that over time they can disappear from the child’s skin and do not interfere with his life, either physically (when moles get touched and torn off), or morally (when children and adults are embarrassed by birthmarks and feel insecure). Vascular moles have the ability to disappear in the first 10 years of a child’s life, but for this you need to seek help from a dermatologist as early as possible.

Reasons for the appearance of moles.

Dermatologist patients are interested in what causes moles to appear. Indeed, what causes the appearance of new nevi?

Genetics. First of all, of course, moles are the echoes of a generation; they are inherited, so if mom or dad, grandparents had a large birthmark or they had similar moles, but the child will probably get it too.
UV rays. As is known, ultraviolet radiation negatively affects human skin. Despite the fact that many people love to sunbathe, everyone understands how negatively it can affect the skin. Think for yourself, because often the love of tanning turns out to be the cause of skin cancer. UV radiation also has an impact on the appearance of new nevi, as well as a negative impact on the development of old formations. Excessive exposure to the sun can cause a benign mole to degenerate into malignant melanoma.
Hormones. Hormones are very difficult to cope with, but you have to monitor your hormonal levels to prevent the appearance of new moles. Hormones rage at different times:

In children and adolescents - during adolescence,
In women and girls - after an abortion, during pregnancy, after childbirth, during menopause,
In men - with damage to the testicles, with a malfunction of the hypothalamic-pituitary system, with increased formation of estrogen, etc.,
Due to illness and stress, infections or birth defects development.

So it's no surprise when you get new moles. There is also a theory that the cause of the appearance of moles is the aging of the body, especially rapid aging.

However, do all moles have the same reasons for their appearance? For example, why do new moles appear that are pendulous or red in color? So, hanging moles are a kind of mixture of nevus and papilloma. They arise due to the fact that the human papillomavirus has probably appeared in the body. Most often, such moles are more confusing due to their inconvenient location and the risk of injury.

Red moles are most likely vascular neoplasms. Causes of red vascular moles May be:

Malfunctions in the functioning of internal organs such as the colon and pancreas;
Failure of lipid metabolism;
Dermatological pathology.

However, only a doctor after an examination can name the exact reason.

What to do when moles appear.

When many nevi appear on the body, people begin to wonder what to do if moles appear. In fact, it primarily depends on the reason and what kind of moles you began to appear. Only a good dermatologist can help with this.

But here’s how you can help: try to keep the following factors in your life under control:

Sunbathe less in the solarium, because... this is not only harmful to the skin, but can also cause new nevi to appear;
You are less likely to be in direct sunlight, because... this has an extremely negative effect on the health of the epidermis;
Before going outside, do not forget to wear a hat at home and be sure to apply sunscreen to your skin. This is especially true in summer;
Try to walk and sunbathe on the beach when it is safe daytime hours– before 10 am or after 16-17 pm;
Watch your health, because... any colds and infections can serve you badly;
Level up your hormonal background to neutralize hormone surges, which will lead not only to feeling unwell, but also to the appearance of neoplasms.

If your new moles don't bother you at all, there's no need to worry, although you may want to see a doctor to make sure they're safe. As a rule, one remedy is used as a treatment - removal of moles from surgical method before modern methods getting rid of nevi.

Red moles are most often removed with a laser, and to prevent the appearance of new red vascular moles, you need to be examined by a dermatologist and undergo a course of treatment, which will be prescribed by a specialist after identifying problems in the body.

If hanging moles begin to appear on the body, then it is necessary not only to remove the moles that bother you and interfere with you, but to seek help from a doctor. The fact is that the appearance is caused hanging moles-papillomas can be a human papillomavirus, the causes of which must be found by a specialist. To prevent new hanging moles from appearing, it is worth undergoing treatment. It is worth removing hanging moles:

Laser removal method,
Electrocoagulative removal method.

IMPORTANT! Remember just one thing - which moles should be removed, which are dangerous, and which cannot be touched only by a qualified dermatologist. Do not try to diagnose your moles yourself, much less “cure” them.

Why do small moles appear on the body? This is the question many patients turn to dermatologists with.

Moles or nevi are present on the skin of any person in small or large quantities, both in adults and in children. But situations arise when their number begins to increase rapidly. Should I be concerned or is this a normal condition?

What are moles?

Moles are pigment spots of various sizes that can be congenital or develop in a person throughout life. The main “building” unit for such formations are melanocytes - epidermal cells containing a special coloring pigment called melanin.

Under the influence of injuries, long stay under direct sunlight, melanocytes are activated, as a result of which they appear on the skin dark spots.

In most cases, spots appear in a child during the first 12 months of life - they are small in size and pale in color.

During puberty, they become larger and more pronounced, which can make a teenager dissatisfied with his appearance. Also, the number of formations rapidly increases during pregnancy or against the background of frequent exposure to ultraviolet rays.

In case pigment spots appear on the surface of the face or exposed areas of the body, it can become serious. cosmetic defect. But the main danger is that they can degenerate into malignant formations - melanoma.

Causes for concern

Many moles on the body or face - this is absolutely normal phenomenon which does not require any treatment.

Contact for medical assistance and it is recommended to remove them in the following cases:

the color of the formation changes;
the edges of the mole become deformed and uneven;
the pigment spot begins to hurt or bleed;
there is itching or burning at the site of the lesion;
the spot begins to quickly increase in size.

It is also best to consult a specialist if the rashes are located in areas where they can be easily damaged by clothing - neck, collarbones, palms, lower back. As a result of such injury, there is a possibility of infection, so it is recommended to remove the formation.

If the moles remain in their normal state and do not change their color or size, there is no cause for concern. The appearance of hairs growing from a nevus does not indicate degeneration into a cancerous formation, but it is strictly forbidden to pull them out yourself.

The only thing allowed if the presence of a hair causes discomfort is to carefully cut it off with scissors.

Reasons for appearance

The main reasons for the rapid appearance of nevi on the surface of the face and body are conventionally divided into 2 main categories - internal and external.

Internal factors are presented various injuries and diseases, external – negative environmental influences.

A sudden appearance of moles can be caused by:

Hormonal imbalance in the body - occurs while taking hormonal drugs, during puberty, menopause, small moles also often appear on the body during pregnancy.
Hereditary factor - if the parents or one of them has a large number of rashes, most likely the child will also have this problem.
Prolonged exposure to direct sunlight - nevi appear in the sun as a result of increased melanin production provoked by ultraviolet radiation.
The process of natural aging of the epidermis and the whole organism.
Allergic skin reactions.
Contact with various chemicals.
Among the external factors, insect bites stand out - mosquitoes and other blood-sucking insects leave behind long-term non-healing wounds, in the place of which pigment spots are formed.

In some cases, the reason that a short time many small moles have appeared, there is a disruption in the functioning of internal organs - the large intestine, metabolic processes, pancreas. Only a dermatologist can determine with maximum accuracy what a sharp increase in the number of rashes on the surface of the face and body means after all the necessary examinations.

Some men and women who find many nevi on the stomach, back or any other part of the body turn to folk remedies based on iodine, celandine or other cauterizing components.

Under no circumstances should such preparations be used to remove age spots. This can not only provoke a severe burn and leave a deep scar, but also cause the formation of melanoma, that is, a malignant neoplasm.

Removal of nevi

If a person has many moles on the face or body in a short time, it is best to consult a dermatologist to determine the exact cause of the changes.

The specialist will prescribe everything necessary tests And diagnostic measures, allowing us to identify the origin and nature of neoplasms, as well as select the optimal removal method.

Small moles are removed using modern methods:

laser beam - allows you to target the area of the tumor without touching healthy areas of the skin; it is a painless and low-traumatic technology with a short recovery period;
cryotherapy – removal through liquid nitrogen, which freezes the mole, promoting its death;
classical surgery - elimination of formation using a surgical scalpel, is rarely used, since deep scars and cicatrices often remain on the skin after surgery;
radio waves – the procedure involves the use of a so-called “radio wave knife”, accompanied by fast recovery and no risk of infection;
electrocoagulation - use electric current, after which the formation completely dries out and dies, leaving no scars or marks.

The decision that this formation on the surface of the epidermis needs to be removed can only be made by a doctor. In case he decides to keep them, the patient is advised to visit a dermatologist and oncologist for regular preventive examinations.

Preventive measures

In order to prevent the appearance of new formations on the skin of the face and body, you need to try to limit as much as possible the factors that can cause them.

Avoiding prolonged exposure to direct sunlight and visiting a solarium will help stop the process of nevi appearing. This will slow down the production of melanin and they will appear much less frequently.

People prone to frequent rashes and age spots, it is recommended to use sunscreens with a high ultraviolet filter. Effective protection from the sun's rays is clothing made of dense materials covering the skin. To protect your face, you should wear a wide-brimmed hat.

Conclusion

An increase in the number of moles is a common occurrence and should not be a cause for concern. A warning sign considered a change in the normal color or size of the nevus, pain, itching, burning, and the appearance of bloody discharge. In such cases, you should immediately consult a doctor to remove the formation.

It is generally accepted that the reasons for the appearance of moles on the body, which can form on any part of the body, lie in the benign local proliferation of melanocytes - dendritic cells of the basal layer of the epidermis.

These are the only cells that synthesize the pigment melanin, which protects the skin from ultraviolet rays and determines the color of the skin, hair and eyes.

In terms of structure and properties, melanin is a UV-filtering biopolymer, which is obtained through a multi-stage biochemical transformation of the α-amino acid tyrosine; the pigment is deposited in the organelles of melanocytes - melanosomes, and enters the upper layers of our skin thanks to keratinocytes.

Accumulating in one place, melanocytes form moles, and their average number in one person is from 30 to 40.

Key reasons for the appearance of moles in adults and children

For the sake of clarification the real reason Based on the appearance of moles, biologists and doctors have conducted and are conducting (and will continue to conduct) numerous biochemical and genetic studies.

At the same time, experts remind that the skin is the most important multifunctional organ, the formation of which occurs during the process of embryogenesis, that is, during the development of the human embryo.

Most moles appear during the first 20 to 30 years of a person's life, and according to statistics, only one in every 100 babies will have moles at birth. And the reasons for the appearance of moles in a child, that is congenital nevi(in Latin naevus means "birthmark") is associated with a minor embryonic malformation in the first twelve weeks of pregnancy.

Melanocytes, which produce skin pigment, are formed from neural crest cells, melanoblasts, which initial stages embryogenesis disperse along the upper (dorsal) part of the neural crest to various parts of the body ( squamous epithelium skin and mucous membranes, hair follicles, arachnoid tissue of the brain). In the basal layer of the epidermis, melanoblasts mature into melanocytes, which are capable of producing melanin. The defect is believed to result in accelerated proliferation of melanocytes.

This means that an excess of them is formed, and “excessive” melanocytes do not spread evenly in the skin, but gather together - in nests, clusters, islands - in the very top layer skin and even protrude from it.

Recent research clears up the picture a little. The fact is that some melanocytes arise from melanoblasts migrating ventrally - along bottom surface neural tube and then along the nerves. These melanocyte precursor cells give rise to peripheral nervous system and adrenal medulla. Thus, they end up in the sheaths of nerves and axons, among Schwann cells, and are able to produce melanocytes after birth.

There is scientific evidence that melanocytes in moles change into so-called dermal nevus cells - skin nevus cells. This option melanocytes differ from normal ones in their size, the volume of cytoplasm and the absence of processes (dendrites). They are usually located at the junction of the dermis and epithelial tissue, and depending on the degree of maturity can be further classified as epithelioid, lymphocytoid and neuroid. It is argued that nevus cells are able to migrate, penetrating into The lymph nodes and even into the thymus gland (thymus), where immunocompetent cells - lymphocytes - form and mature.

To date, it has been established that in 60% of cases, the causes of moles in adults and children are hereditary. More than 125 different genes are already known to regulate pigmentation either directly or indirectly. Many of these genes control the differentiation of melanocytes or influence the biogenesis and function of melanosomes, and also ensure the participation in the biochemical processes of pigmentation and proliferation of epithelial cells of hormones, growth factors, transmembrane receptors (EphR, EDNRB2, etc.), transcription factors (such as MITF, Sox10, Pax3, etc.). The interaction of the totality of all of the above determines the reasons for the appearance of new moles.

By the way, about hormones. Hormonal changes during pregnancy and in patients diabetes mellitus often contribute to the formation of moles. A hormonal reasons The appearance of moles in children and adolescents is explained, first of all, by the activity of hormones and biochemical growth factors (for example, SCF stem cell factor): after all, children grow, and the area of the skin is constantly increasing. Also in a growing body, melanocortins produced by the pituitary gland are very active - hormones that purposefully stimulate the synthesis of melanin (they also affect the production of corticosteroids in the adrenal cortex and the activity of lipid metabolism in adipose tissue cells).

Under the influence of solar radiation, melanin synthesis increases (and we see this when a tan appears). All this is the result of activation of tyrosinase in melanocytes, which provides increased skin protection from UV. Some scientists suggest that excessive sun exposure may play a role in the formation of acquired moles. So far, the biomechanics of the interaction between genetic makeup and overall exposure to ultraviolet rays has not been elucidated. However, the fact that this is exactly the case is evidenced by the almost complete absence of moles on the buttocks...

Causes of moles on the neck, face and armpits

Almost everyone is interested in answers to three questions:

Are there any special reasons the appearance of moles on the face?
What are the causes of moles on the neck?
What are the reasons for the appearance of moles in the armpits - in such an uncomfortable place, which, in general, is not even exposed to the sun?

We will try to answer them, relying on what is already known in clinical dermatology regarding the formation of epidermal nevi of the indicated localization.

Melanocytes are found between basal keratinocytes in an approximate ratio of one to ten and distribute melanin through their elongated processes (dendrites), as well as through direct cell contacts. As is known, keratin skin cells in the upper layers of the epidermis replace each other quite quickly and, rising upward (to the stratum corneum of the skin) carry away captured melanin - to form a barrier from ultraviolet rays.

At the same time, in different parts of the epidermis, the content of melanin and the number of cells producing it are different: in the skin of the head (including on the face), as well as the neck and hands, there are twice as many melanocytes as in other parts of our body. Obviously, this is due to the fact that these areas are much more often open and receive the most sunlight.

Among the as yet unproven versions of the cause of the appearance of moles on the face, there is an assumption that the process of formation of nevus skin cells is facilitated by increased metabolism in the cells of the epidermis - due to the stressful effects of changes in temperature and air humidity on the skin of the face, as well as constant stretching and compression of the skin by facial facial muscles .

In addition, there is an opinion that there may be reasons for the appearance of moles on the neck associated with disturbances in the formation and distribution of melanin in areas of the epidermis directly above the nerves of the cervical nerve plexus (see above about the migration of melanoblasts during embryo development). These are branches of the motor, cutaneous and phrenic nerves, which are connected by loops and are located in the neck (back, front and both sides).

But researchers tend to see the reasons for the appearance of moles in the armpits in the presence of the skin of the armpits hair follicles and glands - sweat and apocrine. But the specific mechanism for the formation of nevi in the armpits has not yet been studied. Moreover, it remains unknown how the flow of melanocytes into the epidermis is controlled, although there is certainly a regulatory circuit this process exists.

Causes of pink and red moles

Most probable cause the appearance of red moles is that the “body” of the nevus can be not only melanocytes, but also epidermal cells connective tissue, adnexal fibers, as well as vascular elements. So-called vascular nevi (nevus vascularis) appear as reddish swellings or spots of varying sizes on the skin due to capillary hypertrophy - the proliferation of blood vessels in the skin.

In addition, there may be a connection with a lack of blood clotting factors and vitamin K, which leads to increased bleeding when the walls of the skin capillaries are damaged, partially trapped in the formation.

According to dermatologists, red moles are characteristic of such diagnoses as autoimmune rheumatoid arthritis or systemic lupus erythematosus.

The reasons for the appearance of red are similar. raised moles. Moreover, their “bulge” (as in the case of brown moles) is the result of the fact that melanocytes are often located significantly above the dermoepidermal junction and are localized in the upper layer of the epidermis, including the granular zone and the stratum corneum.

The reasons for the appearance of pink and red moles do not exclude the influence of the composition of the melanin produced. Melanin can be either brown-black (eumelanin) or reddish-orange (pheomelanin). In the latter case - especially in redheads and natural blondes - the moles are often light beige or pink.

Causes of hanging moles

It is unnecessary to say that the reason for the appearance of a mole on a leg, as well as the reasons for the appearance of hanging moles on the neck, have been thoroughly studied. Although much attention is paid to the study of the etiology of this type of epidermal nevi.

Thus, an association of melanocytic nevus with eccrine sweat glands has been revealed, which is expressed not only in the body of the mole capturing the gland itself (which may be located in the center of the mole), but also in the exit of nevus cells in the form of a node to the outside - through the eccrine ducts.

In other cases, the peculiarity of infiltration leads to a linear distribution pattern of intradermal nevus cells. Extending beyond the dermoedermal border and the papillary layer of the skin, a group of such cells penetrates the surface, expanding the part of the epidermis between the collagen fibers. Moreover, intradermal nevus cells can form a pigmented dome-shaped or papillomatous papule (up to 1 cm in diameter), equipped with a stalk. A mollusc-like form with a wide base, with colors ranging from light brown and black to whitish or pink-red, is also possible.

Hanging moles can form anywhere, but their “favorite places” are the neck area, armpits and skin in the perineal area.

In the middle of the last decade, researchers at King's College in London examined 1,200 female non-identical twins aged 18 to 79 and found that those who had larger number moles on the body, had more strong bones, i.e., they are less likely to develop osteoporosis. In addition, older women with more than 60 moles had less wrinkled skin and looked younger than their age... It turned out that in people with a large number of moles, chromosomes have unusually long telomeres - the terminal sections of DNA polymerase, which prolongs the period of active replication and delays many age-related processes in the body.

And dermatologists advise - regardless of the time and cause of the appearance of moles - to consult a specialist for any changes in epidermal nevi, since the risk of developing skin cancer associated with the presence of moles is quite high.

Age-related moles are pigmented formations on the skin. Spots on the body are present in almost all people, regardless of race or gender. The tendency for more moles to appear with age depends on genetic reasons, skin sensitivity to ultraviolet radiation. Age-related nevi can be benign changes in the epidermis and dermis or a signal of the manifestation pathological changes in internal organs person.

The appearance of pigment spots on the body with age - natural process changes in the skin when metabolism is disrupted. When melanin (the pigment that colors the skin) accumulates, new benign formations. Elements appear singly, in groups of several formations, or in multiples, with localization throughout the body.

In shape, round formations are more common, in the form of hyperpigmented plaques, up to several millimeters in size. Rarely appear on the palms and soles due to the structure of the skin in these areas, less susceptibility to direct sun rays. The favorite place is the head, face, and décolleté. Less common: neck, hands and back, forearms.

There are huge birthmarks and nevi. They can take on a bizarre appearance (stars, fish, triangles).

By it's nature, genetic characteristics, living in latitudes with intense year-round insolation, the risk of acquiring large quantity moles on the body are increasing. Under the influence of constant sun irradiation, lack of protection (special creams with high level protection, underwear) and traumatization, modifications of nevi with malignant degeneration are possible.

Senile moles on the body are the result of excess melanin. There are types:

black nevus - a large accumulation of melanin or germination of papilloma (human papillomavirus, keratoma);
brownish flat round plaques. The appearance is associated with darkening of freckles or a burn of thin skin with the formation of a defect in the form of a nevus;
flat lentigines, tend to appear in groups of plaques under the influence endocrine disorders in organism;
senile senile hemangioma. The formations are red in color. The basis - vascular defect under the skin: dilated vessels located close to the epidermis become visible due to thinning of the skin with age.

Causes of pigment spots with age

Among the factors that provoke the appearance of moles on the skin with age are:

A common reason is hereditary predisposition. In the womb, the development of skin is laid down. With age, the effect of accumulation of pigmented plaques increases.
A direct provocateur of the formation of moles is sunlight. The damaging factor of the sun, affecting the deep dermal layers, enhances. Pigment cells undergo mutation, beginning to divide excessively and spread throughout the body.
When oppressed immune defense body, especially against the background infectious diseases and the aggressive influence of HPV (papillomavirus). Education ( cutaneous horn) have a hard core and may fall off during treatment.
Hormonal changes weaken the protective reaction against skin pigmentation. During pregnancy, in puberty and disruption of the endocrine glands (thyroid and pancreas), the number of moles on the body increases.
Neoplasia and metastatic components initially look like harmless nevi. With the addition of symptoms of malignant formations (suppuration, pain, bleeding) require treatment under the supervision of a physician.
When skin defects with age-related impairment of surface renewal occur, senile pigmentation occurs - chloasma.
With loss of elasticity and protective lipid barrier due to frequent use chemicals(washing dishes, floors) the papillomavirus is allowed to enter the body and, accordingly, the formation of moles.
When red nevi appear, we can talk about a violation internal systems – of cardio-vascular system, work of venous valves, diseases of the liver and gastrointestinal tract.
Individual hypersensitivity to ultraviolet radiation and marbled pale color type of human skin.

Can a mole get bigger with age?

An enlargement of a mole or any changes (bulge, change in color) require consultation with a medical specialist. An increase in the number of moles with age can be absolutely harmless or a sign of disorders in the body. Increases with stretching and loss of elasticity skin, in the presence of inflammatory reactions skin and subcutaneous tissue. It may be a sign of the degeneration of a benign neoplasm into a malignant tumor (melanoma).

Among the signs of malignancy are:

rapid increase in size without prior provoking factors;
asymmetry of the plaque with surface roughness, the effect of a torn edge with a blurred rim;
surface convexity, roughness or excessive softness, peeling, bumps or grooves, cracks;
color indicators with the appearance of unevenness, redness, lightening, blackening;
the surface bleeds, cracks, crusts, purulent contents or ichor appear;
additional discomfort, pain, and may itch.

The presence of one of the symptoms does not necessarily indicate malignancy, but the process should not be started due to a weak immune response and deterioration of skin metabolism. With age, the likelihood of degeneration increases.

Can a mole fade?

There is no need to worry if the mole becomes lighter with age. A normal process, during age-related hormonal changes, hormonal protection decreases, especially in women after menopause. Sometimes the neoplasm completely disappears. It happens in the absence of stimulation of the sebaceous subcutaneous glands, the effect on melanocytes (melanin production is blocked).

With age, the skin loses adequate nutrition from blood vessels, becomes thinner, and lipid substances and sweat are not released. Involves susceptibility to dryness and desquamation, removal of the outer keratinized layer of the nevus with its subsequent fading. Large and dark spots become pale, hanging or convex spots may fall off and become less noticeable.

How to get rid of age-related moles at home

Many traditional methods successfully used to remove or lighten moles. Women often use home recipes to get rid of nevi for aesthetic purposes: when localized on the face, when they are huge in size, causing inconvenience to the owner of the education.

You should first consult with your doctor before treatment. The danger of getting rid of it yourself is provoking wounds at the site of moles and stimulating malignant oncological processes. High risk of scar formation at the site of the removed pigmented plaque. The application of some substances causes burns to surface tissues.

Using willow bark tincture with vinegar. The wood is burned, the resulting ash is mixed in equal parts with table vinegar. Treat the nevus with gruel 2-3 times a day.
A chalk solution with hemp oil dries and scrubs the surface of the birthmark. Apply in a ratio of 1:4. The course of treatment is 1 month.
The juice of plants that have the property of eliminating pigment formations is applied to the area of the plaque: Fresh Juice milkweed, sundew juice, crushed calendula leaves, field celandine. Should be used with caution due to risk of burns.
Using ammonia lotions. Disinfects and cauterizes formations. Do not apply to adjacent areas to avoid irritation or burns. Apply pointwise to condyloma.
A compress made from propolis tincture has a strong anti-pigment, softening, antiseptic property, gently removes formations.
A compress of young aloe leaves, previously crushed and released juice. Apply for 30 minutes and wash off. The course of therapy is 1 month.
Porridge from castor oil And baking soda. Apply under a bandage at night and have an exfoliating effect.
Ointment made from butter and dandelion root. Rub the mixture twice a day.
Lotions made from a concentrated solution of potassium permanganate. Apply for 30 days.
Finely grated garlic mixed with apple or table vinegar. Rub into the area of pigmentation, seal tightly with a band-aid, and leave for a day.

Using alternative medicine It is important to monitor the condition of the skin and at the slightest sign of damage (inflammation, pustules, bleeding), consult a doctor to clarify the condition of the skin.
