Summaries for Giant Congenital Nevus

About this section
Genetics Home Reference:25 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. The nevus may be small in infants, but it will usually grow at the same rate the body grows and will eventually be at least 40 cm (15.75 inches) across. The nevus can appear anywhere on the body, but it is more often found on the trunk or limbs. The color ranges from tan to black and can become darker or lighter over time. The surface of a nevus can be flat, rough, raised, thickened, or bumpy; the surface can vary in different regions of the nevus, and it can change over time. The skin of the nevus is often dry and prone to irritation and itching (dermatitis). Excessive hair growth (hypertrichosis) can occur within the nevus. There is often less fat tissue under the skin of the nevus; the skin may appear thinner there than over other areas of the body.

MalaCards based summary: Giant Congenital Nevus, also known as giant congenital melanocytic nevus, is related to gphn-related hyperekplexia and molybdenum cofactor deficiency, and has symptoms including hydrocephalus, pruritus and hypopigmented skin patches. Affiliated tissues include skin, spinal cord and brain.

NIH Rare Diseases:48 A giant congenital nevus is a dark-colored, often hairy patch of skin that is present at birth (congenital). it grows proportionally to the child. a congenital pigmented nevus is considered giant if by adulthood it is larger than 20cm (about 8 inches) in diameter. giant congenital nevi can occur in people of any racial or ethnic background and on any area of the body. they result from localized genetic changes in the fetus that lead to excessive growth of melanocytes, the cells in the skin that are responsible for skin color. people with giant congenital nevi may experience a number of complications ranging from fragile, dry, or itchy skin to neurological problems like neurocutaneous melanocytosis (excess pigment cells in the brain or spinal cord). they also have an increased risk of developing malignant melanoma, a type of skin cancer. last updated: 5/7/2015
