The objective of this study was to study the clinical, histopathological and histochemical aspects of cutaneous papillomatosis (CP) in cattle (Bos taurus) of the department of Córdoba, Colombia. This study was descriptive, not probabilistic, in animals of convenience. Were used Twenty four bovines with BCP diagnosed clinically and histopathologically. In describing the lesions exophytic and hyperpigmented masses were observed in some cases, pedicled or in the form of cauliflower in others and even in the flat papillomas showed the pedicles to the compression. Similarly, large pendulum papillomas were surgically removed, which when dissected revealed epithelial hyperplasia, hyperkeratosis and the projection of the epidermis to the dermis. At head level, the largest presentation was given in mouth, ears, forehead and eyelids. Histopathologically in the H-E staining, were observed epithelial hyperplasia, acanthosis, digital projections to the dermis and hyperkeratosis. In the T-G staining, marked dermal proliferation of disorganized collagen with little diffuse connective tissue was present, and in the P-R / P staining, marked areas of reddish birefringence and scarce birefringence were observed. The definitive diagnosis of the disease was based on the clinical characteristics, differential diagnosis and histopathological findings, being conclusive as diagnostic methods for CP in bovines in the Department of Córdoba.
