About Large congenital melanocytic nevus

What is Large congenital melanocytic nevus?

Large congenital melanocytic nevus (LCMN) is a type of birthmark that is present at birth. It is a large, dark-colored patch of skin that is made up of melanocytes, the cells that produce the pigment melanin. LCMN can range in size from a few centimeters to several inches in diameter and can be found anywhere on the body. It is usually present at birth, but may not be noticed until later in life. LCMN can be associated with an increased risk of developing melanoma, a type of skin cancer, so it is important to have regular skin checks and to monitor any changes in the nevus.
