Oral papillomatous lesions in a snow leopard. The pale nodules on the bottom of the tongue are papillomas and are indicated by the black circle. The papillomatous lesions are arranged in a ring. This circular arrangement is likely the result of an earlier biopsy in this animal. During the biopsy, viral particles seeded the surrounding skin and caused additional papillomas to form in a circle around the original site of ablation.
