What causes aplasia cutis congenita?
Early rupture of the amniotic membranes, forming amniotic bands, has appeared to be the cause of aplasia cutis congenita in several cases. The bullous or membranous variants of aplasia cutis congenita reveal a distinct histologic pattern identical to those in encephaloceles and meningoceles.
Does aplasia cutis go away?

What trisomy is associated with cutis aplasia?

How does superficial aplasia cutis affect the body?
Superficial aplasia cutis involves only the epidermis (upper layers of skin). Shallow defects usually heal over before the child is born, leaving a scar. Deeper defects can extend through the dermis, subcutaneous tissue, and rarely periosteum, skull, or dura.
What are the complications of aplasia cutis congenita (AC)?
Major complications of aplasia cutis congenita are rare, but can include hemorrhage, secondary local infection, meningitis, or sagittal sinus thrombosis. Larger affected areas associated with underlying bony defects can cause death due to central nervous systeminfection, or hemorrhage from the sagittal sinus.
