Medpundit comes this oddity. This former adolescent had a disease called "yaws", described in this case as "bilateral goundou".
Yaws is almost wiped out as a disease. It is caused by a micro-organism related to syphillis, in this case growing out the bone itself. Imagine what this person would have looked like.
The development of antibiotics blew out the disease in the developed world and today it only exists in tiny levels in Africa.
