Chiropodist: a podiatrist. 

The word chiropodist has essentially dropped from English.  It lost its job to podiatrist. 

A chiropodist was a hand and foot doctor.  The word comes from the Greek words for hand, χείρ (pronounced, kheir) and foot, ποδός (pronounced, podos).

Once again, since it sounds much more impressive to say at dinner parties, “I am a chiropodist,” than, “I am a hand and foot doctor,” English pulled a couple of old Greek words out of retirement and shoved them back into the work force. 

Eventually, though, the hand got tired and went back into retirement, leaving us with the modern podiatrist.
