Here's some good info written on that very subject:
"Rarely do fibromas cause deer any problems but occasionally the location of a large single or multiple clumps of fibromas can interfere with sight, eating, breathing, or even affect the ability of the deer to walk. The attachment of the fibroma is limited to the skin and no evidence of it can normally be found in the muscle. Fibroma presence is typically indistinguishable after skinning the deer.
No human infection from cutaneous fibromas has ever been reported or discovered. Most of the time it is safe to consume the meat of a deer as the tumors only involve the skin. The only concern one should have is when the deer has severe secondary bacterial infection within the warts. Occasionally the larger fibromas acquire a bacterial infection through a break in the skin, which would render the deer unsuitable for human consumption. Therefore, you should discard any carcass and contact the local F&G if the fibromas look like they have been injured or have a foul smell."
