Research Articles On Congenital Nevi

A congenital nevus looks like a patch of colored skin that is round or oval-shaped and usually elevated. They can either be a single or multi-colored colour. They can vary in size from a small spot to something that covers a significant part of our body. They may in some cases have hair growing out of them. Our skin gets its color from cells which produce pigments called melanocytes. Nevi (moles) form when these cells are grouped together at one place, rather than being distributed evenly across our skin. This process occurs during the fetal stage, in the case of congenital nevi. Over time a congenital nevus may get smaller or larger. In other cases, it may become darker, elevated, and more bumpy and hairy, particularly during puberty. In rare cases they may completely disappear. Congenital nevi usually cause no symptoms, but when they are bigger they are occasionally itchy. The skin may also be a bit more fragile and easily irritated than the skin surrounding it.
