Oral papilloma
Like many other mammals, rabbits can suffer from papilloma viruses that cause rough, reddened, wart-like skin lesions. Benign oral papilloma are most common in domestic rabbits but in some regions of the world, a more serious form of the virus can affect other areas of the skin and can develop into a more serious form of cancer. Oral papilloma virus has been observed in domestic rabbits within South and North America, the United Kingdom and the Netherlands.
