A case of canine renal lymphoma of granular lymphocytes with severe polycythemia.

Background: Renal lymphoma in dogs is rare and has a poor prognosis. Granular lymphocyte morphology is rarely reported in canine renal lymphoma. Mild to moderate polycythemia is reported in a number of canine renal lymphoma cases.

Comparison of serum cytokine concentrations between healthy dogs and canine osteosarcoma patients at the time of diagnosis.

Systemic immune responses in cancer patients are of tremendous importance, both to advance understanding of disease mechanisms and for development of new diagnostic testing. Minimal published information is available on the systemic cytokine response in canine osteosarcoma (OS) patients. The goal of this study was to investigate serum cytokine alterations present in OS patients at the time of diagnosis.
