title: Different cell clones in bone marrow and spleen of a patient with chronic myelocytic leukemia (CML) in blastic phase.
abstract: The chromosome study of a patient with chronic myelocytic leukemia in blastic phase revealed a 46,XY,Ph1/47,XY,Ph1,+8 cytogenetic constitution in bone marrow cells and a 46,XY,Ph1/48,XY,2Ph1,+19 cytogenetic constitution in spleen cells. As the cell clones exhibiting chromosome abnormalities in addition to the Ph1 chromosome evolved apparently independently, it is suggested that the acute transformation had a bifocal, myeloid and splenic origin.
