Ocular neoplasms of vascular origin in the horse.

Abstract: HAENIANGIOMAS and haemangiosarcomas are neoplasms of probable vascular origin that occur rarely in the equine eye in a survey there were 21 cases of vascular neoplasia in the skin of horses, and the prevalence of these two tumours was estimated to be 0.25 and 0.02 percent respectively (Hargis and McElwain 1984). Their incidence is likely to be less in the eye than in the skin and in two surveys of equine ocular tumours there is only brief mention of two hacnumgiasarcomas. one involving the lid (Morgan 1969), the other the orbit and lower eyelid (Lavach and Severin 1977). Only two cases of hacmangioma and four of haemarwicaarcorna have been reported. to our knowledge. One hacmangioma was conjunctival (Vesture. Turner and Carlton 1982) and the other conical (Crawley. Bryan and Gogolewski 1987): all four haemangiessarcornas originated in the conjunctiva (Hacker. Moore and Buyukmihci 1986). This report describes the clinical features. histopathology. treatment and follow-up of a case of haemangioma and two of haemangiosarcoma in horses presented to Murdoch University Veterinary Hospital.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research paper discusses unusual cases of ocular neoplasms, specifically haemangiomas and haemangiosarcomas, occurring in horses and details their clinical features, treatment processes, and follow-ups.

Overview of Ocular Neoplasms in Horses

  • The study examines haemangiomas and haemangiosarcomas which are rare tumors presumed to have a vascular origin.
  • Prevalence of these two types of tumors is generally low, occurring at 0.25% and 0.02% respectively.
  • The paper focuses on the occurrence of these tumors in the eye, which is even rarer.

Case 1: Haemangioma in a Thoroughbred Gelding

  • A seven-year-old Thoroughbred gelding presented a lesion on the left eye.
  • The lesion, initially described by the client as a ‘blood-shot vessel’, became more distinct over time. At the time of presentation, it was slightly raised, circular, and 3mm in diameter.
  • Treatment for the horse involved sedation and biopsy of the lesion which was diagnosed as a haemangioma.
  • The affected tissues were then treated with cryosurgery, a procedure involving freezing and thawing cycles to destroy abnormal cells.
  • The horse was discharged and later re-checked. A scar tissue was noted in the area of treatment but no tumor regrowth was reported by the client as of the horse’s destruction due to an unrelated accident.

I’m not able to finish the explanation as part of the research study is missing.
