Plain-English summary
A mixed-breed goat was brought in with a 9-month history of unusual vaginal discharge. After examining her, the vet suspected tumors in the uterus and recommended surgery to remove the affected organs. During the operation, they found multiple masses that couldn't be removed, leading to the decision for euthanasia. An autopsy revealed that the goat had a rare type of tumor made up of two different cancer types in her uterus. This case emphasizes the need for biopsies of all masses to understand their behavior and guide treatment options.

Abstract
An aged mixed-breed goat doe was presented with a 9-mo history of serosanguineous vaginal discharge. Vaginal speculum examination revealed serosanguineous discharge but otherwise no abnormalities. Transrectal ultrasonography showed normal ovaries and multifocal cystic lesions within the uterus. Ovariohysterectomy was recommended because of a strong suspicion of neoplasia. Multiple, non-resectable masses were noted in and around the uterus intraoperatively, and euthanasia was elected. Autopsy revealed multiple masses within the uterus, cervix, and lung parenchyma. Histologically, the masses within the uterus represented a likely collision tumor of primary adenocarcinoma and leiomyosarcoma. Our report highlights the importance of obtaining biopsy samples of all masses because the lesions described showed significantly different biological behavior. This information is vital to guide treatment and prognosis.
