Plain-English summary
A 1.8-year-old Thoroughbred filly was brought in for severe abdominal pain and vaginal bleeding. The vet found an abnormal mass in her uterus through an ultrasound, and during the exam, the mare expelled a piece of this mass. It was diagnosed as hemangiosarcoma, a type of cancer, and the vet performed a hysterectomy to remove the tumor. Unfortunately, the mare developed complications after surgery and was euthanized two weeks later. This case is notable as it is the first report of uterine hemangiosarcoma in horses.

Abstract
A 1.8-year-old maiden Thoroughbred filly, without previous history of mating or reproductive management, was referred for clinical inspection due to the presence of sanguineous vaginal discharge and severe abdominal pain. Transrectal palpation indicated uterine asymmetry, and transrectal ultrasonography revealed a mass near the cervix measuring 8.3 cm in diameter, with heterogeneous echogenicity, a trabeculated center, and a well-defined hyperechoic border. Smaller masses surrounded the larger uterine mass. During the examination, the mare expelled a uterine mass through the vulva. Histological and immunohistochemical (CD31 and Factor VIII) examinations of the expelled mass suggested a diagnosis of hemangiosarcoma. Therefore, a therapeutic hysterectomy was performed, and examinations of the uterine tissue confirmed the diagnosis. However, the mare was euthanized 2 weeks later due to postoperative complications. The animal was subjected to necropsy, and intestinal adhesions in the surgical incision were diagnosed as postoperative complications. No other neoplasms were found during necropsy, establishing the primary origin of the tumor. This case study presents the first known report of uterine hemangiosarcoma in an equine species.
