Moles: congenital pigmented naevi

Congenital pigmented naevi (PCN) are present from birth or appear within one year of birth.

They are light brown to black, more or less heterogeneous, flat or hilly, sometimes warty, and are frequently covered with hair.

Their dimensions are variable. Large naevi can sometimes turn into cancer.

The sometimes unsightly appearance of some of these nevi and the even low risk of degeneration cause them to be removed whenever possible.

The giant mole

The giant congenital nevus, appears at birth. It can cover a large part of the body. It is a rare disease, cells forming the nevus can degenerate and turn into cancer.

Excision is necessary when possible, it can be done in several times.

The excision of a mole

Exeresis is performed by a benign surgical procedure, under local anesthesia, in a few minutes in the doctor's office. She is not painful.

Depending on the size of the nevus, the doctor will make a number of stitches that will need to be removed after a few days.

The removed lesion is sent to the pathology laboratory for analysis.
If it is a skin cancer (melanoma), it may be necessary to intervene again if the entire lesion has not been removed during the first procedure.

The scar will be more or less visible depending on the location of the mole, the age of the person, ability to heal.

To remember

Moles are benign tumors that rarely turn into cancer. Nevertheless, those who have many seem more exposed than others.

In any case, the sun is the main risk factor for degeneration and it is better to limit exposure to sunlight or to protect as much as possible throughout life; this advice is especially valid for people with light skin that easily catches sunburns and little bronze.
