Imagine that almost all newborns are born with clean skin. Now look at your body - from 20 to 40 moles will be counted without much difficulty. What are birthmarks, why, when and where do they appear? We will respond as accurately as possible. You will find out whether it is good or bad if a white halo appeared around the birthmark.
What is a birthmark
Birthmarks on the skin, or nevi, are benign pigmented lesions. They are formed from cells that are located between the dermis and the epidermis - the inner and upper layers of the skin. They consist mainly of melanocyte and melanin cells.
Like all other formations on the human body, the mole goes through its development cycle. Typically, this is first a small speck, mostly flat. Over time, it may rise slightly above the surface of the skin. This all depends on the level at which, in this case, the pigmentary cells-melanocytes are located. If the nevus is flat - these cells are in the epidermis, and as they immerse, the mole is more and more elevated above the skin.
There is a sign that the one who has many birthmarks on his body is happy. Let's make the amendment: the one who even from one birthmark will not have a lot of problems is happy.
Why birthmarks of
appear Nevus, including a mole with a small aureole, can be either a congenital skin defect, or a benign neoplasm that has appeared during a lifetime. According to experts, the reasons for their appearance may be the following.
Information on the location of the appearance of nevi is embedded in human DNA.Very often birthmarks on any part of the body of the father or mother are "mirrored" on the skin of the child. For example, on the nose or on the elbow.
Sunlight, the most active source of such radiation, contributes to the appearance of moles most often. It is under his influence that melanin, the main "creator" of moles, is very intensively produced.
Excess melanin accumulates in small nodules, forming new spots on the body. Numerous nevi are considered a risk factor. After all, no one can say when an inoffensive mole under the influence of ultraviolet will begin its degeneration into a malignant tumor.
The formation of melanin is greatly influenced by the hormone released by the pituitary gland. Sexual maturation, pregnancy, disease or severe stress can lead to the formation of new ones or vice versa - the disappearance of old moles.
Radiation, X-rays, viruses, long-healing injuries or even insect bites can become a triggering mechanism for the appearance of neoplasms on the skin.
Unconventional medicine, Chinese in particular, believes that moles - a kind of traces of a dynamic release of internal energy. The ejection itself is the result of a latent inflammation that promotes the concentration of energy, its stagnation.

Kinds of moles
In its shape and location on the skin moles are divided into:
- Hemangiomas. These vascular formations can be different in size, painted in pink, red or in bluish-red tones. It depends on the vessel from which they appeared. And birthmarks capillary will be flat, superficial;cavernous same - tuberous and nodular, embedded in the thickness of the skin.
- Birthmarks are not vascular. Formed as skin pigmentation, stalk and warty elevations. These are plural or single plaques of various shapes and colors with a horny surface. They can take a variety of sizes and colors - from beige to black, in some cases covered with hair.
There is a classification that distinguishes the skin formations as follows:
Pigmented growth of light or dark color is the birthmark, or flat birthmark. It is located in the upper layers of the epidermis, consists of melanocytes. The number and size does not change over time.
Multiple spots of brown or brownish shade - lengito. The number of them increases quite rapidly in adolescence or senile age. Lentiginosis can enter the disease.
Education in the deep layers of the epidermis - a convex birthmark. Bumpy or smooth, not more than 10 mm in diameter, often with growing hairs. Appears usually on the palms, soles of the feet, in the genital areas.
A small dense and smooth hemisphere up to 2 cm in diameter. is a blue birthmark, or a blue nevus. It rises above the surface of the skin, it can appear on the face, extremities, buttocks. It has different shades and sizes.
Formation of gray, brown or black is a giant pigment nevus. Increases to a huge stain as a person grows up.
Group of formations of various shapes and sizes ( more than 1 cm) - nevus dysplastic. Passed by heredity.
Birthmarks are safe for human health. But in some cases, especially when a mole with a white or red halo appears, the nevus regenerates.

Signs and causes of nevus degeneration
The main signs of the beginning of the birth of a mole may be an itch, a color change, an increase in size, a halo around the mole.
Neovuses with halo - evidence of weak pigment cells. Such a disease of the skin is called Vitiligo. Previously, this infectious disease was considered to be the infectious theory. But recently this hypothesis was rejected.
It is generally accepted that the following factors contribute to the onset and development of the disease: nervous experiences and stresses, a special disease transmitted by inheritance - syringomyelia( spinal cord disease), syphilis, spinal dyspnea, impaired functions of endocrine glands, and others. Violations of metabolic processes, shortage in the body of iron and copper, too, are not the last place in this process.
Why the nevus is white
It must always be remembered that not all changes or formations of moles will entail serious consequences. Appearing new, with a white halo around, a birthmark does not say anything definite. In such cases, two special reasons for its appearance stand out:
- Positive - such a halo is not a sign of something bad. Rather, on the contrary - this is evidence that the pigmentation spot on the skin begins to disappear. It resolves, and this is the reason for the appearance of white color.
- Negative - a mole with a white halo is extremely dangerous. This is not only a threat to health, but also a mortal danger to life itself.
However, you can not determine what happens to birthmarks or diagnose yourself. And in any case, do not try to treat them with any kind of folk remedies or contact a cosmetologist. In such cases, only an oncologist or an oncodermatologist can help. Only specialists will be able to accurately determine what is happening, what changes have occurred in the nevus and in accordance with this will prescribe the treatment.
Removal of the problem nevus
Modern medicine has a rich arsenal of ways to remove moles. To date, there are many methods for carrying out this procedure.
- Scalpel removal under local anesthesia - surgical intervention. After the operation, sutures are applied, which must completely dissipate. But if the mole is large - the risk that there will remain scars remains.
- The most painless, bloodless and leaving no traces - the method of laser intervention. With a laser beam, the nevus is cut off layer by layer, anesthesia is absolutely unnecessary.
- Influence on a pigmentary stain electrocurrent of high frequency - electrocoagulation.
- Removing by means of exposure to cells of the mole of low-temperature nitrogen - the method of cryodestruction. But thus long enough heals wound.
- Cells of the nevus are not destroyed, but are removed by high-frequency radio waves.
It should always be remembered that the springs themselves are safe, but at the same time it is a constant threat. Do not forget to undergo an examination with an oncologist at least once a year, then there will be nothing to worry about.
