Can epidermal nevus become cancerous?

Can epidermal nevus become cancerous?

The tumor is usually benign, although rarely cancerous (malignant ) tumors develop. Some affected individuals have only an epidermal nevus and no other abnormalities. However, sometimes people with an epidermal nevus also have problems in other body systems, such as the brain, eyes, or bones.

Should I remove nevus?

There are several reasons that patients sometimes decide to undergo removal of a large nevus. Most of the time, the overriding reasons to remove a congenital pigmented nevus are first to reduce melanoma risk and second to improve appearance which can be fundamental to improving a patient’s overall psychosocial state.

Is intradermal nevus cancerous?

“Nevus” refers to the mole. “Intradermal” means that the cells of the mole are located beneath the most external layer of skin. Because of this, the birthmark has the same degree of pigmentation as the surrounding skin. In most cases, intradermal nevi appear after adolescence and are benign (noncancerous) skin growths.

What is a sebaceous nevus?

A nevus sebaceous (NEE vuhs sih BAY shus) is a type of birthmark that usually appears on the scalp. It may also appear on the face but this is less common. It is made of extra oil glands in the skin. It starts as a flat pink or orange plaque (slightly raised area). Hair does not grow in a nevus sebaceous.

How do you treat epidermis nevus?

The treatment of choice for small epidermal nevi is surgical excision. Superficial means of removal frequently result in recurrence. Aggressive approaches may be more successful, but also carry a higher risk of postoperative scarring.

How do I get rid of sebaceous nevus?

While they can be removed in a surgical excision, scarring is unavoidable and will be permanent after removal. For those who do choose to reduce the appearance of their nevus sebaceous for cosmetic purposes or to prevent malignant growths, laser treatment can be an effective option.

How common is nevus sebaceous?

This is referred to as nevus sebaceus syndrome, and it is exceedingly rare. A nevus sebaceus (also known as “nevus of Jadassohn”) is an uncommon type of birthmark seen in about 0.3% of newborns.

Can intradermal nevus turn into melanoma?

Atypical Nevi (Dysplastic Nevi) The vast majority of atypical nevi do not become melanomas, but having atypical nevi is a risk factor for melanoma.

Should you remove a sebaceous nevus?

Often, a sebaceous nevus is harmless and less noticeable than a birthmark on the face, and doctors may recommend putting off surgical removal until the child is a bit older. However, if a sebaceous nevus is very large, our surgeons may remove it earlier.

Is epidermal nevus a genetic disorder?

Most epidermal nevus syndromes are thought to be caused by a gene mutation that occurs after fertilization of the embryo (postzygotic mutation), at an early stage of embryonic development. Affected individuals have some cells with a normal copy of this gene and some cells with the abnormal gene (mosaic pattern).
