PG - 70-81 AB - Three of four heifers housed together developed multiple cutaneous tumours in the linea alba and on the teats 3 months after the application of plastic muzzle plates with sharp tips to prevent mutual sucking and licking. Fibropapilloma with many koilocytes but few intranuclear inclusions was diagnosed histologically. The dermis showed neoplastic fibroblasts and a structureless intercellular matrix, and nonpurulent vasculitis was also recorded. Immunohistochemical examination with an antibody against L1 papillomavirus antigen demonstrated intranuclear positivity in single cells of the granular and cornified layers and in many mesenchymal cells in the fibrous parts of the tumours. CD3-positive lymphocytes were present in the wall of some blood vessels, and in the dermis and epidermis. Proliferating cell nuclear antigen was detected predominantly in the basal layer of the epidermis and in the superficial dermis. Electron microscopy revealed small intranuclear aggregates of virus particles in an epidermocyte, damage to desmosomes and disorganization of cytokeratin filaments in many epidermocytes. Aggregates of virus particles were revealed also in a fibroblast in the dermis. In blood capillaries of the corium, acute swelling, inflammation and necrosis of the endothelium were observed. By means of the polymerase chain reaction (PCR) and nucleotide DNA sequencing of the PCR product, the virus was identified as bovine papilloma virus type 1 (BPV 1). The presence of this virus in the tissue was further confirmed by in-situ hybridization with a BPV 1 probe.
