“…Neoplasms in production animals increase economic losses, but surveys on their occurrence are scarce [ 5 , 10 ]. According to the articles and reports reviewed for this review, in the first 20 years of this century, neoplasms in domestic ruminants [ 7 , 8 , 11 , 12 , 13 , 14 ] and in pigs [ 15 ] were studied and diagnosed with greater frequency worldwide. From the 70 studies reviewed, it was possible to extract a total of 1873 cases of spontaneous neoplasms reported in ruminants and swine.…”

Background: Due to the limited information and lack of studies on neoplasms in domestic ruminants, i.e., cattle, sheep, and goats, and domestic swine, the objective of the present study was to systematically review the scientific literature to verify the occurrence, type, organ system, and organs most affected by neoplasms in these animals. Methods: The recommendations of the PRISMA methodology were followed for the elaboration of this study. The research consisted of a systematic review of neoplasms in domestic cattle, sheep, goats, and swine. Results: The number of neoplasms found was 1873. The most affected organ system was the integumentary system with 35.0%, followed in descending order by the alimentary system with 16.90%, the hematopoietic system with 13.50%, the special senses (i.e., eyes and ears) with 10.51%, the female and male genital systems with 7.31%, the urinary system with 4.38%, the liver and biliary system with 3.152%, the endocrine glands with 3.91%, the respiratory system with 2.67%, the nervous system with 2.35%, bones and joints with 0.43%, muscles and tendons with 0.37%, the cardiovascular system with 0.21%, and the pancreas with 0.16%. Of the animals with neoplasms studied, cattle were affected in 69.80% of cases, goats in 10.52%, sheep in 10.46%, and swine in 9.18%. In all species, the most frequent neoplasms were squamous cell carcinomas in ruminants, while melanoma was the most frequent in swine. Few studies carried out in slaughterhouses were found, and the existing ones referred to cattle and swine. No data were found on economic losses with carcass condemnation. Conclusions: In view of the above, it is necessary to carry out extensive and detailed studies that provide knowledge about the impact of neoplasms on the production and condemnation of carcasses in domestic cattle, sheep, goats, and swine and the respective risk factors.

“…Similar results were previously described by several authors [ 8 , 13 , 16 , 21 , 22 ]. It is also important to note that for the bovine species, independently of the organ system, SCC was the most commonly diagnosed neoplasm [ 4 , 7 , 13 , 14 , 16 , 21 ].…”

“…The latter belongs to the Papillomaviridae family which represents the oldest and widest family of viruses ( Abouelkhair and Kennedy, 2022 ). There are several distinct BPVs in cattle that are classified based on their site and type of lesion including BPV-1 ( Mathewos et al ., 2021 ), BPV-2 ( Mathewos et al ., 2021 ), BPV-3 ( Pfister et al ., 1979 ), BPV-4 ( Campo et al ., 1980 ), BPV-5 ( Campo et al ., 1981 ), BPV6 ( Jarrett et al ., 1984 ) and BPV-7 ( Ogawa et al ., 2007 ).…”

“…In adults, BPVs are unable to penetrate the host skin; thus, minimum abrasions in the skin are required to initiate the infection. Exposure of skin lesions to BPV leads to the initiation of infection followed by transformation and proliferation of infected epithelium’s basal cells, which develop into benign papilloma or fibropapilloma ( Mathewos et al ., 2021 ). In the field, there are different types of papillomatosis.…”

Background: Bovine papillomatosis (BP) is considered the most common health problem in large cattle farms. Aim: This study attempts to confirm clinically suspected BP in cattle by PCR assay, histopathology, IHC, and genotyping analysis of local isolates. Methods: According to morphological appearance and lesion features, a cross sectional study of 54 clinically diagnosed BP cattle was assigned to this current investigation from May to August (2021) in Al-Kut district (Wasit Province, Iraq) private veterinary clinics using purposive sampling technique based on set criteria. The cattle were diagnosed clinically, and the tissues were collected and some fixed in 10% neutral buffered formalin and other stored frozen and examined by histopathological technique, immunohistochemistry, and PCR assays. Results: Using PCR assay, all cattle were positive for the BPV L1 gene. According to detect the L1 gene, analysis of the phylogenetic tree showed that local BPV cattle isolates were closely related to the NCBI-BLAST BPV type-1 and type-2 of the Polish equine isolate (KF284133.1) and BPV Brazilian Bos taurus isolate (MH187961.1), respectively. Histological detection showed there were acanthosis, hperkeratosis, epidermal thickening, severe infiltration of mononuclear cells, massive hemorrhage, dermal fibroplasia, multifocal spongiosis, moderate neovascularization, moderate to severe elongation of the retention ridge towards the dermis, parakeratosis, rings of calcification, and necrosis with nuclear pyknosis of some spinosum cells. Immunohistochemical findings of tumor necrosis factor-alpha (TNF-), epidermal growth factor receptor (EGFR) and Fascin showed a significant variation in values of immunoreaction in the dermis and epidermis. These results ranged from negative (0) to mild positive (+1) to moderate positive (+2) reactions. Conclusion: The study provided essential molecular and genotyping data to improve our knowledge by emphasizing the crucial of IHC as an elegant diagnostic method to detect cellular alterations.
