Abstract<\/b><\/p>\n

This case study details a rare diagnosis of recurrent ocular hemangiosarcoma in a horse. It highlights the importance of the veterinary team working in tandem and illustrates the role of the veterinary nurse in assisting with a timely diagnosis and prompt treatment.<\/p>\n

Take-Home Points <\/b><\/p>\n

    \n
  • Hemangiosarcoma (HSA) is a well-documented disease in dogs but is less common in other animals, including cats, cows, and horses.<\/li>\n
  • HSA is a malignant neoplasia that originates in the endothelial cells of blood vessels and, therefore, can travel throughout the body via the vascular system.<\/li>\n
  • HSA can affect any body system and appear as cutaneous, locally invasive, or disseminated.<\/li>\n
  • The life expectancy of horses diagnosed with ocular HSA is 18\u00a0months.<\/li>\n
  • The veterinary nurse plays a vital role in the case of equine HSA, from assisting with diagnostics and providing appropriate sedation and analgesia for standing surgery to ensuring laboratory samples are prepared and submitted properly.<\/li>\n<\/ul>\n<\/div><\/div>\n

    H<\/span>emangiosarcoma (HSA) is a well-documented disease in dogs but is less common in other animals, including cats<\/a>, cows, and horses. HSA is a vascular tumor originating from the endothelial cells that line the inside of blood vessels. Due to the nature of the disease and the fact that it can travel anywhere within the body through the vascular system, it can be present in many different forms, such as cutaneous, locally invasive, or disseminated, and affect virtually any body system. Clinical signs of HSA vary greatly based on location and body system affected; therefore, the disease is often mistaken for other diseases in the initial stages of the workup, delaying diagnosis and treatment and affecting prognosis.1<\/sup><\/span><\/p>\n

    Equine ocular HSA is a rarely documented, yet highly aggressive, vascular tumor that can affect the limbal conjunctiva and nictitating membranes.2<\/sup> Tumors can be removed through a variety of methods, including keratectomy, third eyelid removal, enucleation, or exenteration, and while they are locally invasive, lymphatic metastasis can also occur.3<\/sup> Even with aggressive treatment, prognosis is guarded.4<\/sup> Life expectancy for patients with ocular HSA is 18\u00a0months.2,3<\/sup> <\/span><\/p>\n
