Summaries for Giant Congenital Nevus

NIH Rare Diseases : 54 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 have no other symptoms or may have several symptoms such as fragile, dry, or itchy skin. In about 5% to 10% of the cases the giant congenital nevus is associated with neurocutaneous melanocytosis (excess pigment cells in the brain or spinal cord) and is characterized by neurological symptoms. They also have an increased risk of developing malignant melanoma, a type of skin cancer, especially if the nevus is localized in the vertebral column or when there are multiple associated lesions (satellites). Whenever possible, treatment includes surgery to remove the nevus. In other cases other treatment such as dermabrasion, shaving or facial excision, chemical peels and laser can be done. In most cases, when there are no neurological problems, the prognosis is good, but it is necessary for the lesions to be examined regularly.

MalaCards based summary : Giant Congenital Nevus, also known as giant pigmented hairy nevus, is related to melanocytic nevus syndrome, congenital and nevus, epidermal. An important gene associated with Giant Congenital Nevus is NRAS (NRAS Proto-Oncogene, GTPase), and among its related pathways/superpathways are Regulation of actin cytoskeleton and ErbB signaling pathway. The drugs Lidocaine and Sunscreening Agents have been mentioned in the context of this disorder. Affiliated tissues include skin, brain and spinal cord, and related phenotypes are Decreased shRNA abundance (Z-score < -2) and Decreased shRNA abundance (Z-score < -2)
