Cutaneous fibromas, which are caused by a virus, are confined to the skin and do not affect the meat.
These wartlike growths can cover large portions of the body, but usually are small, single to multiple, and range from a fraction of an inch to several inches in diameter. Often, a virus that enters the deer through a wound causes them. Fibromas are more common in bucks because they are more likely than does to incur wounds while fighting and rubbing antlers.
Although sometimes grotesque in appearance, fibromas generally do no harm to deer. The virus that causes them to grow in whitetails does not infect other wild animals, domestic animals or humans. Fibromas are confined to the skin and, therefore, are removed when the deer is processed for consumption. They do not affect the quality of the meat.
