Some children are born with in. It is also known as pigmented moles. They are a proliferation of melanocytes which produces the pigment cells of the skin. They could be large or small and may cover large areas of the body. Small congenital nevi are 1.5 cm in size and the large ones measure 20 cm or more in size at birth. The aim of the plastic surgery is to remove the mole fully or to the maximum possible extent.
The nevi occur sporadically and are highly unpredictable on when it will occur. Small nevi are noticed in one in a hundred children whereas the big nevi occur in one in twenty thousand births. These moles are black in color. It can also be raised and have excessive hair on it. Since the hair growth is common, they are often referred to as giant nevi. Though the nevi can appear in any part of the body, they mostly appear on the abdomen, back, hips, and butt. Scalp and the face are also prone to nevi.
