Verrucous nevus (ichthyosiform, keratotic, warty) is a benign formation formed by warty-papillomatous growths. Verrucous nevus can have a flesh color or manifest as pigment spots. As a rule, these formations are localized on the skin of the limbs, face or other parts of the body. It belongs to the group of melanomone-dangerous nevi. Diagnosis of the disease is based on anamnesis data, visual examination also plays an important role. Today there are many effective methods of treating verrucous nevus, including laser removal, electrocoagulation, surgical excision and the like.

Verrucose nevus
Verrucous nevus often occurs in childhood, in addition, it can be congenital. Adults very rarely encounter this problem: only 0.5% of the total number of all cases. It is proved that childhood is the most dangerous period in terms of the development of this disease. More often verrucous nevus is diagnosed in women than in men.
Nowadays, the causes provoking the development of verrucous nevus have not been fully studied. Basically, a patient who has been found to have formations has certain problems at the genetic level. The first manifestations of verrucous nevus are recorded even in the process of intrauterine development of the child.
Symptoms of verrucous nevus
This disease has two forms — systemic and localized, differing in symptoms and features of development.
The systemic shape is very similar to a garland and can be located along the body, affecting a large area. As a rule, the systemic warty nevus “settles” only on one half of the body, representing a large number of papillomatous-type formations. They have a brown color, and in the middle — a small part of the unchanged skin.
The localized form is most often based on a limited part of the body. The formation of small sizes — 1 cm, in some cases — 2-4 cm. The “wart” of this type has a bumpy and rough surface. In childhood, there is a slow growth of verrucous nevus, the formation increases in height, not in diameter. In adolescence and adulthood, the growth of the nevus practically stops.
Diagnosis of verrucous nevus
To diagnose this disease, it is enough to examine the patient and find out the anamnesis data. A biopsy and histological examination may also be required. The histological method will allow to study the material taken from the formation in more detail, to identify hyperkeratosis, acanthus or papillomatosis.
Treatment of verrucous nevus
Currently, there are many effective methods of combating verrucose nevus, among which it is worth highlighting:
electrocoagulation;
cryodestruction;
laser removal;
radio wave removal;
surgical excision.
The choice of a particular method depends on the localization of the formation, size, shape and individual characteristics of the patient.
If the verrucous nevus is large, surgical excision must be performed. Also, this technique is used in cases when it is necessary to take material for histological examination.
Radio wave removal is an absolutely painless operation lasting no more than 20 minutes. The procedure is not traumatic, but with large formations, stitches are applied.
Electrocoagulation is performed under local anesthesia. The essence of the procedure is to influence the formation of a high-frequency electric current. The method is not applied to children under the age of two years.
Laser removal gives a pretty good cosmetic result. The procedure is bloodless and sterile. The skin and healthy cells remain intact. This method is often used to remove formations that have affected the face or other exposed areas of the body. But laser removal has its drawbacks: it cannot be used for large formations and does not allow taking material for histological examination.
The essence of cryodestruction is the freezing of verrucose nevus. Under the influence of low temperatures, the formation gradually dies off.
Together with the above-mentioned methods, vitamin therapy can be prescribed to improve the overall condition of the body.
Prognosis of verrucous nevus
Verrucous nevus is a non—dangerous disease, so the prognosis for its treatment is favorable. In most cases, nevi do not grow and do not degenerate into malignant formations. However, this does not apply to cases of permanent injury to the nevus, since such actions can provoke its infection and proliferation.
