Plain-English summary

This case report discusses an 18-year-old Warmblood mare that was diagnosed with uterine fibrosarcoma, a type of cancer in the uterus. Since her last foaling, she had been showing signs of bloody fluid in her uterus and bleeding from the vagina. Unfortunately, the mare was euthanized, and further examination revealed that the cancer had spread to her lungs, liver, and spleen. The tests confirmed that the tumor was indeed a fibrosarcoma. This is the first documented case of uterine fibrosarcoma in a mare.

Abstract

This paper describes a case of uterine fibrosarcoma in an 18-year-old Warmblood mare. The mare had exhibited bloody fluid accumulation inside the uterus and vaginal haemorrhagic discharge since the previous foaling. The mare was euthanized, and on pathological examination, in addition to the uterine neoplasia, multiple metastases were found in the lungs, liver and spleen. The histological and immunohistochemical examination determined that the tumour was a fibrosarcoma. To our knowledge, this is the first paper to describe a uterine fibrosarcoma in a mare.
