Human child with diprosopus condition. Diprosopus means “two-faced” in greek. It is a congenital deformity in which craniofacial duplication occurs; one or more facial features, or even the whole face, is duplicated on the child. This medical anomaly is extremely rare but is documented on both animals and humans.
Correction: as people have pointed out, this newborn child is also anencephalic. I chose to deliberately leave that out because I did find the diprosopus condition a bit more exhilirating :3
