A 9-year-old, spayed female Golden Retriever dog was referred to us for lymphocytosis and lymphadenopathy, secondary to suspected chronic lymphocytic leukemia (CLL). The dog had a clinical history of anorexia, vomiting and melena lasting two days. The popliteal lymph node contained small-to-intermediate lymphocytes, which led us to suspect low-grade lymphoma. Thickened lesions in the stomach and small intestine were detected by ultrasonography. Histopathology of the popliteal lymph node and small intestine revealed a simultaneous presence of T-zone lymphoma (TZL) and high-grade gastrointestinal (GI) cytotoxic T-cell lymphoma. Large granular lymphocytes (LGLs) were seen on cytological examination. Polymerase chain reaction (PCR) revealed that both lymphomas originated in the T-cells. The dog died 15 days after diagnosis, despite chemotherapy.
