| Abstract: | True lymphoid leukemia of bone-marrow origin may present as two distinct clinical forms in the dog. Acute lymphoblastic leukemia is a rapidly progressive disease associated with proliferation of malignant, undifferentiated lymphoblasts. Chronic lymphocytic leukemia is a more insidious form of malignancy associated with abnormal proliferation of small lymphocytes. Recognition of these clinically distinct forms of leukemia and their differentiation from lymphosarcoma are important in considering prognosis and approach to therapy. |
