Nevus Becker


Benignnevus Beckeris a limited area of ​​hyperpigmented skin that is densely covered with hair. A specific feature of this disease is the complete exclusion of cancerous degeneration of the spot. But despite this, patients with such a skin lesion should undergo a thorough diagnosis to exclude giant melanocytic pathology. Treatment is carried out exclusively on cosmetological indications.

Causes of nekus Becker

Hairy nevus occurs due to unknown reasons for today. Specialists point to the following risk factors:

  1. Frequent sunburn and prolonged exposure to ultraviolet radiation.
  2. Chronic trauma of the epidermis.
  3. Decreased immunity and stressful situations.
  4. Genetic predisposition.

In the molecular structure of the affected area of ​​the body, doctors note an increased amount of melanin, which is responsible for coloring the skin. But the amount of melanocytes, the cells that generate the pigment, remains within the normal range. Scientists also found in the nevus cells a large number of receptors for male hormones. This fact explains the hair on the nevus.

Symptoms and clinical course of the disease

The peculiarity of this pigmented neoplasm is the absence of manifestations after birth. The first signs of pathology can be found in 10-14 years, when a teenager develops a hormonal imbalance.

This disease is mainly diagnosed in boys in the upper limbs.

In the initial period, patients pay attention to the formation of a hummocky spot, which can be yellow. Gradually the neoplasm widens in size and captures a large area of ​​the skin.

Hairy pigment nevus is formed during puberty and, as a rule, at this time the growth of the growth is stabilized.


In most cases, the diagnosis of "nevus Becker" is not particularly difficult. Diagnosis is based on examination of the skin and dermatoscopy (examination of the epidermis through a magnifying device).

This disease should be distinguished from melanoma nevus, which has a high probability of cancer degeneration and is a congenital pathology.

What is the danger?

Numerous clinical observations indicate that this lesion is not life-threatening and can not be transformed into a cancer tumor.

Indications for surgery are cosmetic discomfort.

Modern methods of treatment

The most optimal period for radical excision of the neoplasm is the initial phase, when the pigmented spot has a yellow color and small size. In such cases, experts recommend a laser removal.

Laser therapy is based on high-temperature evaporation of nevus tissues under the action of laser beams.

It should be noted that such treatment can only slightly reduce the pigmentation of the skin.

Traditional surgical operation is not the most ideal method of therapy. Radical intervention, as a rule, is limited by the size and location of the nevus. Also to the shortcomings of surgery can be attributed postoperative scars and inflammation of the epidermis.

Is it possible to remove hair on the nevus?

Dermatologists point to a real possibility of extracting hair from a problem area. This procedure should be performed by an oncologist. In this case, hair removal can be carried out both mechanically, chemically, and with the help of laser technology.

The result of surgical manipulation, as a rule, does not completely eliminate the cosmetic defect of the skin. Laser therapy and radical intervention allows a little clarification of the problematic part of the body.

Most oncologists testify thatnevus Beckeris not a precancerous condition and does not require immediate treatment. Moreover, doctors recommend that this lesion be treated in the presence of significant aesthetic discomforts.
