Selected pathological changes of the mare uterus and ovary.

The research focuses on diverse pathological conditions affecting the uterus and ovary of mares, exploring their diagnosis, possible causes, significances, and remedial measures.

Uterine Pathologies

• The study delves into different types of focal enlargements on a mare’s uterus which can be palpated through the rectal wall. A plethora of causes are discussed and the authors hypothesize that certain factors could contribute to these uterine conditions.
• With regard to the diagnosis of these enlargements, potential pathogeneses are considered. The authors also debate their significance and possible treatment protocols, suggesting avenues for further investigations.
• Another uterine anomaly investigated is lymphatic lacunae, often found in aging mares. While they often give rise to sizeable endometrial cysts, they usually result in widespread alteration throughout the uterine horns.

Ovarian Abnormalities

• The authors highlight three unusual ovarian abnormalities in mares. The first abnormality is a large, estrogen-producing granulosa cell tumor.
• The second anomaly is a large follicle producing estrogen in a four-month-old filly. This case is particularly intriguing due to the young age of the affected filly, pointing to a potentially early-onset of the condition.
• The third ovarian condition explored is an ectopic, progesterone-producing structure located near the adrenal gland. This condition appears to be bordering on neoplasia, indicating the possibility of a malignant transformation.

Overall, this research offers comprehensive insight into specific pathological conditions affecting the reproductive organs of mares, providing valuable contributions to the existing body of veterinary pathology literature.
