Aplasia cutis congenita is a condition in which there is congenital (present from birth) absence of skin, with or without the absence of underlying structures such as bone.[1] It most commonly affects the scalp, but any location of the body can be affected.[2] While most people with aplasia cutis congenita have no other abnormalities, some people have congenital malformations involving the cardiovascular (heart), gastrointestinal, genitourinary, and central nervous systems.[1] The cause of this condition is unclear and appears to be multifactorial (many different factors appear to play a role); contributing factors may include teratogens, genes, trauma, and compromised skin perfusion.[1]
