title: The morphological studies on M2/t(8; 21) acute nonlymphocytic leukemia.
abstract: Bone marrow studies including morphological, morphometrical and ultrastructural aspects were performed in 35 patients with M2/t(8; 21) and 23 patients with M2/NN. It was found that M2/t(8; 21) patients had higher cellularity in bone marrow. Type (II) myeloblast cells were predominant among myeloblasts. Deformation of nuclei, nucleocytoplasmic asynchronism and dysmegakaryocytopoiesis were more evident in M2/t(8; 21) than in M2/NN patients.
