Causes of appearance


Setton's nevus is a pigmented growth around which there is a discolored patch of skin. It slightly protrudes over the skin and does not cause pain. Most often it is diagnosed in a child or adolescent.

Doctors do not know exactly why Sett's nevus arises in a person, but it was noted that it can appear in patients with vitiligo or the development of autoimmune diseases. There is evidence that this formation is able to hit close relatives of people who have been diagnosed with vitiligo.

There is an opinion that its appearance is associated with a skin reaction to ultraviolet radiation. As a confirmation of this fact called the situation when the appearance of the nevus Setton was preceded by a long stay in the open sun.

There is an opinion that the appearance on the skin of a nevus is directly related to autoimmune processes in the body. This is due to the fact that in patients with this diagnosis, a lot of cytotoxic antibodies were detected in the blood. And the formation around the nevus of the white ring is explained by the breakdown of melanocytes as a result of the action of immune cells on them.

In the risk group are people:

  1. Often staying in the open sun for a long period of time, abusing procedures in the solarium and periodically getting sunburned skin.
  2. Those who have already been diagnosed with vitiligo or close relatives of patients with this diagnosis.
  3. Those with a tendency to develop autoimmune processes in the body.
  4. Inclined to frequent stress and depression.


Nevus Setton is formed in two stages:

  • at the initial stage there is a pigmented spot that looks like an ordinary birthmark;
  • further around the birthmark appears white edging.

In some cases, doctors identify an intermediate stage, which is characterized by a preliminary acquisition of the skin that surrounds the neoplasm, a pink hue. After that, it gradually turns pale and becomes white.

Like a birthmark, the nevus slightly rises above the skin and has clear boundaries. In this case, its shade can be from the color of "coffee with milk" to a saturated brown, rarely it has a red tint. The rim that appears around the nevus has a larger diameter.

More often than not Setton's nevus is diagnosed on the chest, back or stomach of a person. They can be single or multiple. In a child, education can disappear on its own for several years after its appearance.

However, physicians advise to regularly monitor him and consult a doctor when:

  • change its outlines (if they become fuzzy or blurred);
  • darkening of education;
  • the onset of an inflammatory process in the nevus;
  • the appearance of pain or bleeding neoplasm.
According to studies, single nevi are unable to degenerate into malignant formations, unlike multiple ones.

Settone's nevuses usually do not cause complications, except for cases when the patient combs them or damages them in another way. Because of the ingress of pathogens into it, it is possible to develop inflammation, suppuration of the wound, the toxins from which quickly enter the blood, causing signs of intoxication.

Especially dangerous such a state can be in children, so parents should explain to them that they can not be touched. If the nevus is on an open area of ​​the body, then on a sunny day, going outside, it should be sealed with a band-aid or lubricated with a special sunscreen with a high degree of protection.



When identifying any unusual neoplasms on the body, a person should consult a dermatologist.

To confirm the diagnosis, the doctor will give the patient an examination:

  1. A laboratory blood test that can detect inflammation and determine blood coagulability.
  2. Instrumental examination for establishing the stage of pathology and its features:
  3. Dermatoscopy is a method of hardware research, which is always prescribed in case of painful formation or change in its hue.
  4. Siascopy is a procedure that assesses the structure of education and the definition of melanin and melanocyte levels in it.
  5. Biopsy - examination of nevus tissue for malignant formation.
Manifestations of Settus nevus can be similar to other skin pathologies (leukopathy, neurofibroma, etc.). To confirm the diagnosis, the doctor will conduct a differential diagnosis.

Such a neoplasm may outwardly resemble some types of melanoma. Therefore, if the doctor has a doubt about the nature of the lesion, then to exclude malignant process, he will conduct a tissue biopsy followed by a histological examination of the sample.


Special therapy does not require a neoplasm, however, before the beginning of regression of Setton's nevus, the patient needs to undergo regular examination at a dermatologist. In connection with the fact that it does not cause any discomfort, the use of medicines is not required for a person.

To increase the defenses of the body, the doctor can prescribe the patient general restorative means:

  • Aevit - not prescribed for cholelithiasis or pancreatitis;
  • extract of echinacea - not suitable for the treatment of pregnant women and children younger than 7 years;
  • Immunal - suitable for the treatment of children and adults;
  • Vitrum Beauty - appoint only adults;
  • Coenzyme Q10 - is contraindicated in children younger than 14 years.
Physiotherapy methods in the treatment of nevi are not used due to lack of effectiveness. If during the examination the patient shows signs of malignant formation, the doctor will prescribe an operation to remove the depigmented skin area.

To speed up recovery people's methods of treatment help:

  1. In the morning and in the evening you need to take a small amount of magnesia powder. The course of treatment is 4 weeks.
  2. A small amount of chalk powder is poured into the place where a nevus is formed and bandaged on top with a handkerchief.
