Verrucous nevus

Verrucous nevus (Verrucous nevus), also known as epidermal nevus, linear epidermal nevus, etc., usually onset at birth or early childhood, but it also appears before the age of 10 to 20, and can be affected by both men and women. Usually manifested as light yellow to brownish black wart damage. Its size, shape and distribution are different. Most of them are papillary uplifts, arranged in ribbons, lines, or patches, and can occur everywhere in the body, usually in a linear arrangement. Occurs on one side of the body. Occurs in and around the male and female genitals and anus. At this time, it is often misdiagnosed as condyloma acuminata.

Cause:

The disease belongs to a congenital verrucous hyperplasia of epidermis, which develops since childhood.

Clinical symptoms:

It is more common in children, the incidence of both sexes is equal, and it can occur in any part of the body. In most cases, it is wart-like hyperplasia, brown or black. Small papilloma-like spines, irregularly shaped ridges, and greasy surfaces when touched. Long or short strips, the strips run very irregularly. No symptoms, just unsightly.

Prevention:

Laser treatment can be performed under local anesthesia. There will be a little imprinting after the operation, but it is basically normal skin.

1. Verrucous moles, also known as linear moles, are usually arranged linearly. Occurs on one side of the body. Smaller skin lesions can be removed surgically. If the skin lesion is too large, skin grafting is required after resection. The lesion can also be treated with electrocautery, laser and liquid nitrogen cryotherapy. Preschool treatment is better.

2. On both sides of the bridge of the nose, the skin is thin, and the subcutaneous fat is also thin. The veins walking underneath can look like bruises and blood stasis through the cortex, but hemangioma should be ruled out.

Identification points:

Verrucous moles often occur unilaterally, are arranged in a linear shape, are harder, and have a clean damaged surface and are not easy to bleed. Except for some special parts, there are often the same rashes elsewhere. The medical history is long, and the efficacy of topical drugs is poor. Pathological changes of the epidermis showed varying degrees of hyperplasia, mainly hyperkeratosis, papilloma-like hyperplasia, and spinous hypertrophy, increased melanin in the basal layer, and vacuolated cells without condyloma acuminatum. Pathological identification is easier.
