thumb|A chick with two beaks and three eyes Diprosopus (, "two-faced", from , , "two" and , [neuter], "face", "person"; with Latin ending), also known as craniofacial duplication (cranio- from Greek , "skull", the other parts Latin), is an extremely rare congenital disorder whereby parts (accessories) or all of the face are duplicated on the head.
== Development == Although classically considered conjoined twinning (which it resembles), diprosopus is not normally due to the fusion or incomplete separation of two embryos. It is the result of abnormal activity by the protein SHH (sonic hedgehog).
