Aplasia cutis congenita is present at birth and is characterized by small midline posterior ulcers of the scalp that heal with scarring. A significant number of cases have been reported in families; the cases appear to be of autosomal dominant inheritance. This paper highlights the genetic aspect of the disease by presenting three observed cases in three successive generations of one family.
