Plain-English summary

A 17-year-old Arabian gelding was examined and underwent tests, including an ultrasound of the chest and abdomen, which led to a diagnosis of gastrointestinal cancer that likely spread throughout the abdomen. The owner decided to euthanize the horse and chose not to have a postmortem examination done. However, testing of the fluid from the abdomen confirmed that the horse had B-cell lymphoma, a type of cancer affecting the immune system.

Abstract

After physical examination, ultrasonographic evaluation of thorax and abdomen, and peritoneal fluid analysis, gastrointestinal neoplasia with suspected diffuse peritoneal metastasis was diagnosed in a 17-year-old Arabian gelding. The owner elected euthanasia and declined postmortem examination. Immunocytochemistry analysis of the peritoneal fluid resulted in a diagnosis of B-cell lymphoma.
