Plain-English summary

A 5-year-old Quarter horse broodmare was brought in after showing signs of not eating, being depressed, and having diarrhea, 13 days after she aborted a fetus at 9 months of pregnancy. The veterinarian ruled out other serious conditions and used ultrasound and fluid tests to investigate further. Unfortunately, they found that the mare had a type of cancer called multicentric B-cell lymphoma affecting her uterus and ovaries. Sadly, the mare did not survive, as the cancer was confirmed during a post-mortem examination.

Abstract

A 5-year-old Quarter horse broodmare was evaluated for inappetence, depression, and diarrhea 13 days after aborting a 9-month gestation fetus. Clinical and laboratory examination ruled out uterine rupture and peritonitis. Ultrasonography of the uterus combined with cytological analysis of peritoneal fluid suggested the existence of diffuse lymphoma. A multicentric B-cell lymphoma involving the uterus and ovary was confirmed at necropsy and histopathological examination.
