Plain-English summary
A 3-year-old Quarter Horse mare had been losing weight and eating less than usual for about a month, and she became very tired. Her condition suddenly got worse just two days before she passed away. A post-mortem examination showed a large mass in her abdomen and fluid buildup, which was pushing her intestines out of place. The diagnosis was an ovarian teratocarcinoma, a type of cancer that had spread to nearby lymph nodes. This case highlights a rare and serious type of tumor in horses.
Abstract
A 3-year-old Quarter Horse mare presented with an approximate 1-month history of progressive weight loss, anorexia and lethargy that abruptly worsened 48 h before death. Post-mortem examination revealed free flocculent fluid and a large mass within the ventral abdomen that dorsally displaced the caecum and large intestine. An ovarian teratocarcinoma with metastasis to regional lymph nodes was diagnosed histologically. Although benign teratomas are the second most common ovarian neoplasm in equids, reports of malignant teratomas in horses are rare. This report documents an unusual presentation of a rarely reported malignant neoplasm of the reproductive tract in horses.
