Aplasia cutis congenita

Case of an infant with a rare condition known as aplasia cutis congenita of the parieto-occipital region. Aplasia cutis congenita is a condition in which there is congenital absence of skin, with or without the absence of underlying structures such as bone. It most commonly affects the scalp, but any location of the body can be affected. While most people with aplasia cutis congenita have no other abnormalities, some people have congenital malformations involving the cardiovascular, gastrointestinal, genitourinary, and central nervous systems. The cause of this condition is unclear and appears to be multifactorial; contributing factors may include teratogens, infection, intrauterine trauma, and compromised blood flow to the skin. Surgical repair is not usually indicated in aplasia cutis congenita (ACC) if the defect is small. Small underlying bony defects usually close spontaneously during the first year of life, although larger defects sometimes need reconstruction.
