Plain-English summary
A 6-year-old standardbred gelding suddenly collapsed while training and showed signs of severe bleeding from the nose and struggled to breathe before being put to sleep. Before this incident, he had been performing poorly, seemed very tired, and had swelling in one eyelid with watery discharge from his eye. After he passed away, a thorough examination revealed that he had thoracic lymphoma (a type of cancer in the chest) along with bleeding in the lungs caused by exercise. Unfortunately, the treatment options were not applicable as the horse was euthanized due to the severity of his condition.
Abstract
During training, a 6-year-old standardbred gelding collapsed, exhibiting severe epistaxis and agonal breathing and was euthanized. The horse had a recent history of poor performance, lethargy, and unilateral eyelid swelling with serous ocular discharge. Postmortem and histopathologic examination findings revealed thoracic lymphosarcoma and concurrent exercise-induced pulmonary hemorrhage.
