How common is blue nevus?

Although nearly anyone may develop a blue nevus, they are more likely to appear in females than in males. Blue nevi are also more prevalent in Asian populations. Most blue nevi are benign, but there is a chance that a cellular blue nevus may develop into a form of melanoma. However, this is rare.

What is giant congenital nevus?

Giant congenital melanocytic nevus is a skin condition characterized by an abnormally dark, noncancerous skin patch (nevus) that is composed of pigment-producing cells called melanocytes. It is present from birth (congenital) or is noticeable soon after birth.

Is epidermal nevus hereditary?

Epidermal nevi are genetically ‘mosaic’, meaning that the mutation causing the nevi are not found in other cells of the body. Mosaicism arises when the genetic mutation occurs in one of the cells of the early embryo sometime after conception; such mutations are called ‘somatic’ mutations.

What is congenital melanocytic nevus?

Congenital melanocytic nevi (CMN) are visible pigmented (melanocytic) proliferations in the skin that are present at birth. CMN are benign, tumor-like malformations resulting from faulty development of pigment cell (melanocyte) precursors in the embryo, and composed of an abnormal mixture of skin elements.

Is Becker nevus genetic?

Summaries for Becker Nevus Syndrome The condition is thought to be sporadic (occurring in individuals with no history of the condition in the family).

What causes Becker’s nevus?

Becker’s nevus is due to overgrowth of the epidermis (upper layer of the skin), pigment cells (melanocytes) and hair follicles. The specific underlying cause is unknown.

Can a nevus grow back?

Q: Can a benign mole grow back after removal? A: If a mole has been removed by cutting it off so that it is level with the skin, some cells may remain below the skin. These can act as a “seed” and cause it to regrow. It is not possible to predict whether it will grow back.

What does nevus look like?

A common mole (nevus) is a small growth on the skin that is usually pink, tan, or brown and has a distinct edge. A dysplastic nevus is often large and does not have a round or oval shape or a distinct edge. It may have a mixture of pink, tan, or brown shades.

What is a hairy nevus?

A congenital pigmented or melanocytic nevus is a dark-colored, often hairy, patch of skin. It is present at birth or appears in the first year of life. A giant congenital nevus is smaller in infants and children, but it usually continues to grow as the child grows.

What is Nevus of Ota?

Nevus of Ota is a dermal melanocytosis originally described by Ota and Tanino in 1939. Clinically, nevus of Ota is distributed along the ophthalmic and maxillary divisions of the trigeminal nerve and presents as a blue or gray patch on the face.

How do you lighten Becker’s nevus?

The best approach to a Becker’s nevus is to use a hair reduction laser along with either a Q-switched laser to lighten the lesion or a fractionated ablative laser.

Can nevus be removed?

Is Removal Possible? Small nevi can be removed by simple surgical excision. The nevus is cut out, and the adjacent skin stitched together leaving a small scar. Removal of a large congenital nevus, however, requires replacement of the affected skin.

Can a nevus turn into melanoma?

Most melanocytes are in the skin, and melanoma can occur on any skin surface. It can develop from a common mole or dysplastic nevus, and it can also develop in an area of apparently normal skin. In addition, melanoma can also develop in the eye, the digestive tract, and other areas of the body.

Does Becker’s nevus spread?

Becker’s nevus (also known as “Becker’s melanosis”, “Becker’s pigmentary hamartoma”, “nevoid melanosis”, and “pigmented hairy epidermal nevus”) is a skin disorder predominantly affecting males. The nevus can be present at birth, but more often shows up around puberty….Becker’s nevusSpecialtyUnknown2 more rows

Does Becker’s nevus go away?

Treatment of Becker naevus There is no effective treatment for the majority of Becker naevi. However, the dark brown colour is less obvious if the affected area is kept out of the sun so that it doesn’t tan. The excessive hairs can be reduced by repeated treatments with a hair removal laser or by electrolysis.
