Plain-English summary
A 12-year-old Belgian draft horse was brought in because of a mass on the right eye's third eyelid and red discharge that had been present for three months. The mass was surgically removed and later found to contain both hemangiosarcoma (a type of cancer affecting blood vessels) and squamous cell carcinoma (a skin cancer). Unfortunately, about 16 months after the surgery, the horse developed thickened eyelids and bleeding from the eye again, leading to euthanasia. Further examination confirmed that the cancer had returned and spread to nearby areas.

Abstract
A 12-year-old Belgian draft horse presented for a right eye third eyelid mass and red-tinged ocular discharge of 3 months' duration. The third eyelid was excised and submitted for histopathology. On histopathologic examination, the mass was composed of both hemangiosarcoma and squamous cell carcinoma. The horse developed thickened eyelids and hemorrhagic ocular discharge from the right eye approximately 16 months following surgery, and was euthanized. Necropsy and histopathology confirmed local recurrence and regional metastasis of the hemangiosarcoma. This was an unusual case because there were two distinct neoplastic processes composing the same mass that could not be differentiated grossly.
