Cutaneous porphyria

Cutaneous porphyria is a disorder that causes blisters, excess hair, swelling, and necrosis of the skin. It can cause red colored teeth and fingernails, and after exposure to sun, urine can turn purple, pink, brown, or black. The disease is thought to be connected to the many werewolf and vampire legends of the past, where a sufferer (who would have lived apart from society) might have been confused for a monster. The disease is part of the more general group of disorders called porphyrias which cover a range of mental and physical disorders due to the overproduction of certain enzymes in the body. The disease gets its name from the Greek word “porphura” which means “purple pigment”.

I was going to add a picture but might get infractions so feel free to image google "cutaneous porphyria" and you'll see a Krang lookalike.

And you are telling us about this because...you suffer from it?

Because the disease is thought to be connected to werewolves and vampires, i'm just trying to save the world here.
