His serum protein immunoelectrophoresis demonstrated monoclonal IgA lambda and bone marrow aspiration revealed plasma cells 20%. Two months alter, hematological examinations showed erythrocytosis, luecocytosis and thrombocytosis. The bone marrow showed hypercellular with increased plasma cells and monoblasts. Serum vitamin B12 and vitamin B12 binding proteins confirmed the diagnosis of polycythemia vera. After treatment with Busulfan, Prednisolone and Endoxan for 6 months, his blood examination revealed increased monocytes, metamyelocytes and myelocytes. Bone marrow examination confirmed the diagnosis of acute myelomonocytic leukemia with plasma cells.
