Good God, what is wrong with that man's legs? What the hell is that?
Ooh, boy... the juxtaposition of watching "Good Eats" and thinking I'm hungry and then watching that trailer. It seems so mean to fill the bulk of the trailer with these people without clothes.
Anywho, my guess is that guy has a whopper of an infection, secondary to severe lymphedema. Skin basically can't take the swelling, so the skin gets damaged, and infection ensues.
Add: Here's a good guess of what it is. Mostly describes what I posted, but more medical: elephantiasis verrucosa nostra.
A Google image search reveals maybe that is it.
I decided to watch again (I'm getting further and further away from finally eating dinner), and maybe it's severe cellulitis...? It's not terribly red, but cellulitis with healing spots and new abscesses may look like that. Lymphedema is definitely worsening whatever it is or outright causing it.
That's it. I'm outta bullets, lol.
EVN sounds like the disease.
