My son was born with cutis aplasia congenita. He had two midline spots on his scalp, one spot was 11mm in diameter and the other spot was 13 mm. They have finally healed now and it took about 2 months. I was wondering if there is any research out there for a cause or if it is known what causes it. I have taken him to four different doctors who have never seen it before and don't have a lot of information on it. He did have genetic testing done at birth which all came back normal.
