Its called either a fibroma tumor or papilloma. Papilloma is a warty growth caused by a viral infection. I actually have one in a jar of formaldihyde. Mine is about the size of a lemon and the doe that had it tasted just like any otherdeer I have killed. Although I was a bit weary about that hind quarter.

Anyway, I just ran for my book and these are "not transmitted to man, are seldom injurious to the deer, and although papillomas are common they occur in less than 1 % of deer. "

They are only skin deep and I can attest to that with my doe. After skinning, it was tough to see where the growth was.

That was years ago and I'm still here. It could account for the way I am though!
