Other lesions, such as seborrheic keratosis and soft fibroma, also go through this mistake. "

The main types of warts

The following three experts explain the main types of warts and how to recognize each:

Common or common warts

As the name already says, are the most common warts that exist. Its appearance is rounded and rough, without different coloring of the rest of the skin. They manifest mainly in the areas of greater friction of the body, such as hands, knees, elbows and fingers. They can occur from childhood and are benign, that is, they do not lead to other diseases.

Plantar warts

Popularly known as "fish eye", plantar warts appear on the soles or soles of feet - so many Sometimes they are confused with corns. Its appearance is rough and grayish. Although warmer and more difficult to treat, they are benign warts.

Flat warts

Flat and yellowish, they usually appear on the face and are often multiple. Flat warts do not lead to the development of other diseases.

Filiform warts

They are benign and thin warts, which look like a wire or a snake. They are more common in older people or with low immunity. They can be present anywhere on the body, especially on the face, neck and eyelids.

Periungual warts

With the same appearance as common or common warts, periungual warts have the differential of occurring around the nails and they are benign.

Subungual warts

They also have the appearance of common or common warts, but subungual warts appear under the nails, that is, beneath them. They may be visually hidden because of the use of dark enamels, but it is impossible not to notice that something is different, since they make the nails grow crooked or undulating. They are benign warts.

Anogenital warts

Occur in the genital, perianal, oral and urethral regions and are usually associated with STIs. They are more resistant to treatments and, although not exactly malignant, may be precursors to malignant tumors, such as uterine cancer and penile cancer, so they deserve special attention.

What to do when noticing a wart

The first measure to take when you notice a wart of either type is to go through an appointment with a dermatologist. In the case of anogenital warts, both the gynecologist and the urologist can examine and continue with the necessary treatment.

In addition, the wart must always be removed, whether benign or potentially malignant. "It is advisable to remove them because they are viral and can spread to the body as much as to contaminate other people," says Guilherme.There are many ways to remove a wart: electrosurgery, cryotherapy (freezing of the wart with liquid nitrogen), curettage, chopping and acid application in the office or home removal (for common or vulvar plantar warts). Treatment will depend on the physician's assessment and indications.
