Aplasia cutis congenita is a condition in which there is a congenital (present from birth) absence of skin with or without the absence of underlying structures such as bone.[1] This absence of skin most commonly affects the scalp, but any location of the body surface can be affected, including the truck, arms, and legs.[2] Most patients with aplasia cutis congenita have no other abnormalities, although the condition may be associated with congenital malformations involving the cardiovascular, 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); teratogens, genetic factors, trauma, and compromised skin perfusion each seem to play a role.[1]
