Whitetail Doe With Terrible Growth Near Mouth

August 08, 2017  •  Leave a Comment

Back in 2009 I photographed this Whitetail Doe with a terrible looking growth near her mouth. This was at the Sequoyah National Wildlife Refuge in Oklahoma. I have seen Deer with large growth on their bodies before, but not one like this one. It looks like it could burst at any moment.

I did some research and I discovered that Deer get a common skin disease called Fibromatosis. I'm not sure if this is what this Doe has, but it could be. I also read that Infected deer behave normally unless the location of the fibromas blocks vision or results in other physical impediment to normal activities.

Fibromatosis In Deer Facts

  • Large, warty growths, or fibromas appear as firm, round, nodular, hairless, pigmented skin abnormalities adhered to or incorporated within the skin of deer. 
  • The masses occur most frequently around the eyes, mouth, face, neck, and forelimbs, and may appear as a single mass or numerous growths. 
  • In a survey made in New York state it was found that the incidence of fibromatosis is highest in deer 2.5 years of age and younger, and 5 times higher among bucks than does.
  • Infected deer behave normally unless the location of the fibromas blocks vision or results in other physical impediment to normal activities.
  • Fibromatosis is not an important cause of deer mortality. The disease is not known to infect humans.
  • There is no reason to believe that fibromatosis of deer is infectious to domestic animals.
