Q84: Other congenital malformations of integument

The group of conditions classified under "Other congenital malformations of integument" refers to a variety of abnormalities of the skin, hair, and nails that are present from birth. These malformations occur when the outer layer of the fetus's developing body, called the integumentary system, does not form correctly during the early stages of pregnancy. The exact cause of such malformations can vary, and might be due to genetic factors, exposure to harmful substances during pregnancy, or a combination of both. Symptoms depend on the specific malformation, but may include unusual skin color or texture, abnormal hair growth or absence, nail deformities, or unusual marks or growths on the skin. The progression of these conditions can vary, with some remaining stable over time and others changing or evolving. These congenital malformations primarily affect the skin, hair, and nails, but may also impact other body systems depending on the severity and type of malformation.
