A 7-month-old castrated male French Bull dog was presented with vomiting, lethargy, anorexia and weight loss of 2 weeks duration. The patient's history and clinical manifestations of suspected hepatopathy were subjected to ultrasonography, radiography, biochemical investigations and cytology of hepatic lesion. The cytologic impression was hepatic lymphoma, which was later confirmed by histopathology. The neoplastic cells were strongly diffusely immunoreactive for PAX5, but not immunoreactive for CD3, and B lymphocyte specific clonal proliferation was detected using by assay of antigen receptor rearrangement. Large numbers of immunoreactive mature non-neoplastic lymphocytes were admixed with the neoplastic cell population. Therefore, the immunohistochemical results were definitively consistent with a T-cell rich B-cell lymphoma (TCRBCL). This is the first description of a hepatic TCRBCL in a juvenile dog showing a poor response to aggressive chemotherapy.

A 5-y-old female Golden Retriever was presented with a 2-wk history of hyporexia, vomiting, diarrhea, lethargy, weight loss, polyuria, and polydipsia. Clinical examination and ultrasonography revealed multiple organ enlargement with gallbladder and kidney nodules suggestive of disseminated neoplasia. Hematologic and biochemical analyses revealed pancytopenia, hypercalcemia, and monoclonal IgA gammopathy suspicious for a plasma cell neoplasm. Bone marrow and blood smear examination revealed neoplastic atypical cells highly suggestive of lymphoid origin. Autopsy confirmed the presence of homogeneous white masses and multifocal pale infiltrates in the spleen, kidney, small intestine, gallbladder, and urinary tract. Histologic features were consistent with a multicentric atypical plasma cell tumor. Tumor cells were negative for CD204, IBA-1, E-cadherin, CD3, CD5, CD79a, CD20, and PAX5, and positive for MUM1, consistent with plasma cell origin. The presence of > 20% of circulating blastic plasma cells was consistent with primary plasma cell leukemia with plasmablastic morphology, a disease rarely described in veterinary medicine.
