For what ? Poland syndrome is an uncommon but easily recognized pattern of birth defects that are thought to arise from poor blood flow to the involved structures during fetal development. Its limitations are usually evident on exam and stable. If you have specific concerns about origin, heredity or other issues feel free to ask or consult with a clinical geneticist.
