We examined a 26-month-old steer with neoplastic lesions in the spleen, lymph nodes, heart and kidneys, characterized by pleomorphic lymphoid cells that were immunohistochemically positive for CD20. The presence of bovine leukemia virus (BLV) at >200,000 copies per 100,000 cells by quantitative RT-PCR was considered to be due to random integration of the provirus into the neoplastic cells´ genomes. Inverse PCR identified the presence of one, two, two and three different malignant clones in the heart, spleen, mesenteric node and blood, respectively. Because BLV can rapidly induce lymphoma and a high proviral load facilitates B-cell carcinogenesis, multiclonal tumor development was suspected in the present case.
