Exposed, the case of a bull pure Simmental breed, age 9, with the presence of skin lesions, consistent with squamous level eye and nose cells. It is performed clinical evaluation and pathological characterization of skin lesions, these being exophytic granulomatous appearance with erythema, edema, scaling with crusting, firm and presence of exudation Serosanguinous. Subsequently, after sedation and application of local anesthesia it was taken biopsy tissue from the periphery of the cancerous lesion punch of 6 mm subsequently fixed in 10% formalin and taken to the Laboratory of Pathology of the Department of Animal Science, University of Cordoba, Colombia, where they were processed until paraffin embedding. Finally, the sample was stained with hematoxylin - eosin (HE), where the presence of islands with central core surrounded keratin tumor cells was confirmed and branching cords of neoplastic epithelial cells with varying degrees of squamous differentiation and high presence of mitosis. The final diagnosis was well-differentiated squamous carcinoma cells.

Slaughterhouse inspections play a crucial role in the sanitary control of zoonoses and foodborne diseases. This study aimed to identify and analyze the frequencies of lymph node diseases in cattle slaughtered for human consumption, using the samples sent to the anatomic pathology service of the Federal Laboratory for Agricultural Defense ( Laboratório Federal de Defesa Agropecuária), Minas Gerais, Brazil, from January 2015 to September 2022. In total, 2000 lymph node samples were analyzed, and additional information was individually retrieved. Lesions were most frequently identified in thoracic lymph nodes. Bacterial isolation and quantitative polymerase chain reaction (qPCR) were performed using samples suspected of tuberculosis. Tuberculosis cases accounted for 89.3% of the samples. Histopathology was more sensitive than other ancillary tests for diagnosing tuberculosis. Paraffin-embedded tissues from lymphoma cases were subjected to immunophenotyping using anti-CD3 and anti-CD79a immunohistochemistry. Frozen and/or paraffin-embedded tissues from lymphoma cases were used to identify the enzootic bovine leukosis (EBL) retrovirus through qPCR. Other diagnoses included primary (T- and B-cell lymphoma) and metastatic neoplasms (squamous cell carcinoma, pulmonary adenocarcinoma, undifferentiated carcinoma, undifferentiated adenocarcinoma, undifferentiated sarcoma, undifferentiated round cell tumor, mesothelioma, hepatic carcinoid, meningioma, and seminoma), actinogranulomas (pyogranulomatous lymphadenitis [actinobacillosis and actinomycosis]), idiopathic lymphadenitis (neutrophilic and/or histiocytic, granulomatous, and suppurative), and miscellaneous nonspecific lymphadenopathies (depletion/lymphoid atrophy, lymphangiectasia, erythrocyte drainage, parasitic eosinophilic lymphadenitis, follicular hyperplasia, and toxic granulomatous lymphadenitis). The combination of histopathology with complementary techniques is important for successful diagnosis, especially in complex cases of high epidemiological, economic, and zoosanitary importance, such as tuberculosis and EBL.
