Of course! Well, i mean - what desease it can be? I was searching for an answer but found none, you know. I only know that he suffers from something like pneumonitis in anime but but blackened limb isn't a symptom of this desease.
Well, I don't think it is a desease that exists in real world, probably it is just something the author imagined.
