Verrukovy nevus is pigmented formation, which is a warty growth over the skin. Verrux nevus has a tuberous surface, consisting of individual segments (externally resembling cauliflower); dark color. In contrast to melanoma-sensitive nevi, characterized by slow growth, not prone to ulceration and bleeding. Differentiating verrukous nevus from other skin tumors allows carrying out dermatoscopy, biopsy and histological examination. Removal of the verrux nevus can be performed surgically, by radio-wave method, by electrocoagulation, laser coagulation, cryodestruction.
Symptoms of a verrucous nevus
The localized form of the verrux nevus is a new growth over the skin up to 1 cm, rarely 2-4 cm. It consists of papillomatous outgrowths of the skin tightly adjacent to each other. The rough and bumpy surface of the nevus makes it look like a wart . Such formations can be several in different parts of the body. In childhood, there is a slight increase and an increase in the number of nevi. And the growth of a nevus is noted more in height than in diameter. In adulthood, there is no growth, and in adolescents, only those nevi that have apocrine and sweat glands are enlarged.
Diagnosis of Verrux nevus
Diagnosis is based on a visual examination of education and history data, indicating its appearance in childhood and the absence of sprawl. To confirm the diagnosis, a biopsy and a histological examination are performed, which reveals the unevenness of the granular layer of the epidermis, the presence of hyperkeratosis, papillomatosis and acanthosis. Verrux nevus is differentiated from acne vulgaris, ordinary wart, red flat lichen.
Treatment of verrux nevus
Surgical excision of verrux nevus is used for large sizes of education and in situations where its careful histological examination is necessary. Radio wave removal of the nevus is less traumatic. But with a large amount of education for the remaining after the removal of the wound has to overlap.
The layered laser removal of the nevus gives a good cosmetic effect, is an absolutely sterile and bloodless method. However, it does not provide the possibility of histological examination of the removed material, since in the removal process, the evaporation of the tissues takes place. The removal of localized forms can be performed by electrocoagulation.
