Can a blue nevus go to cancer?

.

The appearance of nevi, that is, birthmarks, is a benign process that is caused by the movement of melanoblasts in the period of intrauterine development.Blue nevuscan be observed at different ages, but most often it appears during sexual development.

Subjectively no clinical symptoms a person does not note. The mole grows slowly, so it can go unnoticed for quite some time.

Features

The blue birthmark is a "colored" not too large neoplasm on the skin. The color of the birthmark is mostly blue or darkish blue.

Often, nevi appear as single entities, however, their multiple accumulation is possible. They are characterized by benign origin, but it is worth noting that they have a high risk of cancer malignancy.

What is dangerous for a blue nevus?

The growth of the nevus is mostly very slow, but in some cases its proliferation may indicate malignancy of the cells. It is worth noting that cancer, due to malignant transformation of the birthmark, is not so frequent, but it's worth to be careful.

A distinctive feature of a benign birthmark from melanoma is its constancy sizes, uniform unchanging color, absence of additional formations or cracks and growth hair on it.

Often, differential diagnosis is performed between nodular melanoma and a rapidly growing nevus. Malignant degeneration is observed mainly in the honeycomb type of the blue nevus on the scalp. The danger of this kind of birthmark is the risk of degeneration in melanoma, regardless of localization (skin, genitals, lymph nodes or cervix).

If there is bleeding, discomfort, itching, discolouration and the size of the birthmark, you should consult with your doctor as early as possible and conduct a thorough examination.

Can a blue nevus go to cancer?

The risk of degeneration of the birthmark into a malignant form always exists. Often melanoma is formed under the following conditions:

  • large nevus sizes from birth;
  • widespread defeat;
  • the appearance of a mole in old age;
  • a large number of nevi on the body;
  • constant appearance of new birthmarks;
  • localization of the nevus in places with maximum traumatism, for example, in the area of ​​the cuff, girdle or bra.

To timely suspect malignancy, it is necessary to know what a benign nevus looks like. It looks like a knot with clear contours, an oval shape and a size of up to 1 centimeter.

Coloration depends on the amount of pigment, so the birthmark can be dark blue, blue or blue-black, while unevenly colored.

Education can rise above the skin. The touch feels like a dense knot, its surface is smooth and has no hair.

The conditions under which education can transform into melanoma

As mentioned above, the presence of a mole on the skin is a risk of malignant formation due to the negative factor. However, not all nevi are subjected to malignancy.

Increase the likelihood of malignancy, the following factors:

  • trauma of the birthmark with a bruise or abrasion;
  • prolonged friction in the areas of the collar, waistband, cuff, etc., that is, when the nevus is gradually damaged and atypical cells appear during the regeneration of tissues;
  • Congenital and dysplastic kinds of moles are most often affected by malignant degeneration;
  • if the size of the pigmentary lesion is more than 20 millimeters;
  • location of the nevus on the skin of the face;
  • Multiple lesions with nevi, when the number of formations on the body exceeds 20;
  • excessive sunlight or frequent stays in the solarium. Especially negatively on the surface of the birthmark sunlight affects during their maximum activity (11.00-16.00 day);
  • immunodeficiency;
  • hormonal disorders;
  • infectious diseases.

Separately, it is necessary to focus on the traumatic factor, which in most cases is the cause of degeneration into cancer. Suppose that the nevus is located in the most frequently exposed place and is injured daily during shaving or bathing with a washcloth. In this case, it is recommended to remove the formation in advance in advance, in order to prevent traumatization and malignancy.

If you notice that the nevus has changed, you should consult your doctor in the near future. The following changes are possible:

  • rapid increase;
  • violation of the integrity of the surface in the form of cracks or peeling;
  • there were aching, twitching, pricking, itching sensations in the area of ​​a mole;
  • inflammation along the circumference of the birthmark in the form of a rim;
  • loss of clear outlines;
  • change in color;
  • appearance on the surface of droplets of blood.

Transformation of blue nevus in melanoma

If a similar transformation is detected, it is also possible to damage nearby lymph nodes. They can become painful, dense to the touch, enlarged, immobile and welded to surrounding tissues in the form of a conglomerate.

Should I remove the blue nevus?

It is not necessary to delete each formation, however, when changing its appearance, it is recommended to consult a doctor for diagnosis.

Blue nevuscan be removed by electrocoagulation, cryodestruction, laser or surgical excision. However, regardless of the method of removal, the nevus must necessarily undergo a histological examination.
