Bovine papillomatosis is a frequent cosmopolitan infect-contagious disease, mainly in dairy bovines. This work had as objective to describe the macroscopic and histopathological aspect of bovine cutaneous papillomatosis (BPV). Were used nuliparous, primiparous and multiparous females of Holstein Friesian crossbreed showing different types of cutaneous papillomas (typical, atypical, filamentous and mixed) and of degrees defined for this study: light (25% of the body affected), moderate (50% of the body affected) and intense (more than 50% of the body affected). For histopathological evaluation, the animals were submitted to cutaneous biopsy of the cutaneous lesions. Macroscopically, the papillomas presented color, aspect and form well defined. The papillomas were most present in the lateral abdomen, dewlap and snout, showing mixing injuries, followed for basal. In the histopathological analysis there were observed epithelial and conjunctive hyperplasic alterations with extensive vegetative growth of the epithelium, with wide and deep epidermal crest, these results characterize phase of development with viral replication and synthesis, being a characteristic finding of papillomatosis. It can be concluded that dairy bovine cutaneous papillomatosis presents predilection for specific areas, with papillomas of distinct forms and aspects. KEY WORDS: Bovine papillomatosis, macroscopic and histopathological aspects.
