The morphological studies on M2/t(8;21) acute nonlymphocytic leukemia
- 12 Downloads
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.
