Abstract:

In the present clinical case the presence of cutaneous horn of 4 months of evolution in the phalanx of the left anterior limb in a 3-year-old French Bulldog canine is reported, the collective surgical ablation of a sample (4.5 x 3.2 cm) of two Phalanges of the left anterior limb, which included skin, hair and nail, for macroscopic examination and excisional biopsy of the phalanges. Histopathological study determines as a presumptive cause the canine papillomavirus, a lack of confirmation by immunohistochemistry, PCR and / or molecular sequencing. The development of papillomavirus-induced lesions in adult dogs is often associated with the immunosuppression of underlying diseases or drugs, such as corticosteroids and cyclosporine, however in this case it did not present previous diseases or ingests of immunosuppressive medications. The objective of this work is to report the first documented case in Latin America of a canine cutaneous horn allegedly associated with Papillomavirus infection.
