That yellow thing not sure what it is

Without being able to look at it in person it could be a number of things, it could be dry skin, it could be an old scab, but i think it is most likely to be a bit of dried boar glue.

Ditto @Soecara. I'd watch it to make sure it doesn't get any larger, change colors or anything like that, but it sure seems to be that it's probably boar glue. If it is, it'll disappear all by itself.
