- 2 groups:
- Fibropapillomas: viral DNA sequences, but no virus found
- Epithelial Papillomas: virus found
- Calves most commonly affected
- Usually resolves spontaneously
- Can undergo malignant transformation to alimentary carcinomas
- Usually concurrent with grazing bracken (co-carcinogen) and ingesting quercetin (immunosuppressant)
- Can cause squamous cell carcinoma of the eye in Hereford cattle, where UV light acts as the co-carcinogen
