Corneal squamous cell carcinoma in a dog.
Summary
A Golden Retriever was treated for corneal intraepithelial neoplasia, a type of squamous cell carcinoma in situ. Surgical removal followed by cryotherapy successfully prevented tumor regrowth one year post-treatment.
Area of Science:
- Veterinary Ophthalmology
- Ophthalmology
- Oncology
Background:
- Squamous cell carcinoma in situ, also known as corneal intraepithelial neoplasia, can affect animals.
- Previous ocular injury is a potential risk factor for developing corneal tumors.
Observation:
- An 11-year-old Golden Retriever presented with corneal intraepithelial neoplasia in its right eye.
- Papillomavirus antigen was not detected in the excised tumor tissue.
Findings:
- The tumor was surgically excised using lamellar keratectomy.
- Double freeze-thaw cryotherapy was applied to the surgical bed post-excision.
- No tumor regrowth was observed one year after the combined treatment.
Implications:
- Lamellar keratectomy combined with cryotherapy appears to be an effective treatment for corneal intraepithelial neoplasia in dogs.
- This case highlights the successful management of a rare ocular tumor in a canine patient.
- Further research could explore the long-term efficacy and potential complications of this treatment protocol.
