Third eyelid resection as a treatment for suspected squamous cell carcinoma in 24 horses.

The research article revolves around the surgical removal of the third eyelid in horses suspected of having squamous cell carcinoma. The study reviews 24 cases between October 2000 and January 2007 and provides insights based on long-term follow-ups.

Research Methodology

• The researchers examined the medical records of 24 horses brought in with suspected third eyelid squamous cell carcinoma, from October 2000 to January 2007.
• These records were analysed retrospectively to gather data on the cases.
• Follow-up communication was conducted through telephone calls with the horse owners and referring veterinary surgeons to monitor the progress post-surgery.
• Out of 24, the resected third eyelid tissues of 21 horses were submitted for histological examination. The remaining 3 did not undergo examination due to the owners’ financial concerns.

Research Findings

• Out of the 21 examined cases, 16 were confirmed to have squamous cell carcinoma.
• Three cases were histopathologically diagnosed as lymphoid hyperplasia, a condition characterised by an abnormal increase in the number of lymphocytes.
• One case was identified as a mast cell tumour, which is a type of cancer that typically affects the skin.
• One case was diagnosed as a sebaceous gland adenocarcinoma, a rare form of cancer that begins in the oil-producing glands of the skin.

Long-Term Follow-Up

• The researchers conducted a long-term follow-up over an average duration of 41 months to track health progress post the resection surgery.
• No recurrence of squamous cell carcinoma or associated complications were detected during the follow-up.
• Out of the 16 confirmed cases of squamous cells carcinoma, six horses were euthanized for issues unrelated to the surgery or the carcinoma during this period.

Overall, this research paper gives a comprehensive analysis of the use of third eyelid resection as a treatment for suspected squamous cell carcinoma in horses. It provides valuable input about the effectiveness of the method and can be referenced for future clinical decisions and studies.
