Overview

A giant congenital nevus is a dark-colored, often hairy patch of skin that is present at birth. It is usually smaller in infants and children, but continues to grow with the child. A giant pigmented nevus is usually larger than 20cm in diameter once it stops growing. They are often found on the buttocks, which is known as "bathing trunk" nevi. Individuals with giant congenital nevi have an increased chance of developing some type of skin cancer, including malignant melanoma.[1][2]
