This study was undertaken to investigate the prevalence of papilloma virus and granulomatous reaction which occur naturally in sheep in Mosul area, Iraq. These lesion were diagnosed in 10 cases out of a total 325(3%) examined cases, papilloma percentage was 1.23% and granulomatous infection percentage was 1.84% .The gross and microscopic features of papilloma showed a red tissue nodule hanging from the inner surface (mucosa) of the lower lip .Microscopically, the mass was formed from multiple papillary protrusions of fibrous connective tissue with marked increase in the number and size of inflammatory cell . The macro and micro examination of granulomatous reaction showed a subcutaneous and neoplastic mass of tissue which were connected to the jaw bone at the level of seventh and eighth cheek teeth and upon opening the skin .A white mass was observed while the microscopic exam showed the presence of a severe fibrous reaction in the form of inflammation and neoplasm granuloma. Finally, this research determined the type of papilloma and granulomatous reaction in local sheep and their prevalence rates, with accurate description of gross and microscopic lesions.
