Is it on his other leg? it might just be a color changing mark. other than that it could be a burn (unlikely speaking its on the inside of the leg) It might also be a bacterial infection but I am not that experienced. You could take him to the vet for a checkup. I AM NO PROFESSIONAL IF MY INFO IS WRONG PLEASE CORRECT ME IF I DONT SOUND RIGHT PLEASE WAIT FOR ANOTHER USER OR FACT CHECK ME.

Looks to be the tail, not leg. It doesn't look like a burn to me...if anything it may be some sort of fungus infection. Do you have any other pictures showing? Does it darken or lighten with him or does it always stay the same color?
