Plain-English summary
An eight-year-old neutered male border collie was brought in with a painful left eye and a red bump on the side of his eye that had been bothering him for six weeks. He had previously lost his right eye due to trauma. The vet removed the mass and treated the area with a special type of radiation (strontium-90 beta radiation) to help prevent cancer from coming back. After a few months, another similar mass appeared, which was also surgically removed and treated with radiation. Fortunately, 86 weeks later, there were no signs of cancer returning in his eye.

Abstract
An eight-year-old, neutered, male border collie dog was presented with a six-week history of left ocular discomfort and a raised, red mass at the lateral limbus. The right eye had been enucleated approximately 12 months previously following suspected trauma when the eye had become red and painful. The mass was excised using superficial keratectomy/sclerectomy and the surgery site was treated with strontium-90 beta radiation. Histopathological findings were consistent with a diagnosis of haemangiosarcoma. Immunohistochemical staining showed uniform expression of CD31 in neoplastic cells, confirming their endothelial origin. Two further treatments with strontium-90 beta radiation were applied to the surgical site at weekly intervals. Twenty-six weeks after surgery, a second, raised, red limbal mass became apparent at the medial limbus of the left eye. Surgical excision and adjuvant strontium-90 beta plesiotherapy were performed as described for the initial tumour. Routine histopathological analysis confirmed haemangiosarcoma at this site. Eighty-six weeks following the initial presentation, no recurrence of ocular haemangiosarcoma was evident.
