This guy is who I call Junkyard, looks like a big mature bodied deer with a very odd rack. He also has a serious goider growing off of his chin, its not just the crappie moultrie cam he had it in every pic. He will have his lungs deflated if given the chance.

Hey So. Iowa! Awesome deer ya got there. i have a cow that i just had to lance open that had an identical looking absess on her jaw. it was just a mesquite thorn infection though. typically not deadly but quite frequent down here in texas. I dont know if there might be similar thorny plants up there ( never been, but want to). the skin often times in those areas is too tough to rupture. might be the same case, but might be something more serious as well. Great looking deer though!
