QUEBRADA, S. F.  and  RAMIREZ, L. D.. Ocular squamous cell carcinoma in cattle of the Gray Brahman breed: case report. Rev. Med. Vet. Zoot. [online]. 2023, vol.70, n.2, pp.234-244.  Epub Apr 16, 2024. ISSN 0120-2952.  https://doi.org/10.15446/rfmvz.v70n2.104915.

In this paper a 5-year-old Brahman breed bovine is reported, which was submitted by presenting a mass in the third eyelid of the left eye which obstructed vision. Histopathological analysis of the submitted sample shows a well-differentiated squamous cell carcinoma with no evidence of lymphovascular invasion. The therapeutic management consisted of exenteration to avoid recurrences, for which the patient's evolution was satisfactory without causing problems in his productive performance. It has been described that a possible risk factor is related to permanent exposure to sunlight that affects the replication of DNA in cells and induces tumor processes. While it is true; in cattle breeding systems where females spend most of the time grazing and are exposed to ultraviolet radiation, this would explain the reason for the presentation of this neoplasm in this type of patient. In this sense, it is essential to pay attention and monitor abnormalities that may occur in cattle, whether Zebu or Taurine.

Keywords : neoplasia; ultraviolet radiation; zebu; epithelium; skin.
