Plain-English summary
This case involves a mare that had two different types of tumors in one of her ovaries. For five years, she showed signs of not having regular heat cycles, which is a sign of reproductive issues. After surgery to remove the affected ovary, the tissue was examined and found to have a mix of two types of tumors. Following the surgery, the mare was able to return to her normal heat cycles and became pregnant the next breeding season. Overall, the treatment was successful.
Abstract
Ovarian tumours in mares represent 2.5% to 6% of the most frequent neoplasms found in the equine species, with a higher chance of benignity. This study aims to describe a case of two different tumours found in the same ovary of a mare that presented clinical signs of suppressed oestrous cycle during 5 years. After unilateral ovariectomy, the ovary was sent to the histopathology examination which determined a mixed tumour of granulosa cell and leiomyosarcoma. After treatment, the mare returned to oestrus and got pregnant in the next season.
