title: Peritoneal fluid immunocytochemistry used for the diagnosis of a possible case of equine gastrointestinal B-cell lymphoma.
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.
