Slayer's guitarist Jeff Hanneman's scar after surgery

(c) ? Scar tissue: impressive !

Jeff Hanneman contracted necrotizing fasciitis, likely caused by a spider bite, and has been undergoing surgeries, skin grafts and intense rehab.
Tom Araya on Jeff's disease :"Jeff ended up contracting a bacteria that ate away his flesh on his arm, so they cut open his arm, from his wrist to his shoulder, and they did a skin graft on him, they cleaned up… It was a flesh-eating virus".
