Extensive bone marrow infarction followed by myelofibrosis in patient with Ph' positive chronic granulocytic leukaemia.
A 28-year-old man with Philadelphia chromosome positive chronic granulocytic leukaemia developed extensive bone marrow and bone infarction which was associated with anaemia and thrombocytopenia. He survived 20 months from the first symptoms of bone marrow infarction; during this time he developed myelofibrosis and osteosclerosis followed by blastic transformation. Extensive bone marrow infarcti...
متن کاملClonal evolution in atypical chronic granulocytic leukemia: a non-Philadelphia translocation.
Hemopoietic cells in chronic granulocytic leukemia (CGL) frequently contain a chromosome translocation involving chromosome 22 and another autosome, usually number 9. The translocated chromosome 22 is known as the Philadelphia (Ph) chromosome. The appearance of a second Ph chromosome is the most common cytogenetic abnormality in CGL signaling the blastic phase. For 6 yr we serially studied a ma...
متن کاملChronic myelodysplastic syndrome (preleukemia) with the Philadelphia chromosome.
A patient with severe anemia, reticulocytopenia, and erythroid hyperplasia of the bone marrow developed fatal acute nonlymphocytic leukemia after 3 yr. A Philadelphia chromosome with the typical 9/22 translocation t(9q +;22q-) was identified by banding techniques in a small number of bone marrow cells throughout the preleukemic phase of the illness (14%--38% of metaphases) and during the acute ...
متن کاملLymphoid blastic crisis in Philadelphia chromosome-positive chronic granulocytic leukemia following high-grade non-Hodgkin's lymphoma A case report and review of literature.
In this paper we describe a case of a 65-year old man with a lymphoid blastic crisis of a chronic granulocytic leukemia occurring seven years after a palatine tonsillar non-Hodgkin's lymphoma treated with chemotherapy and radiation therapy. Bone marrow cytogenetic study demonstrated the presence of the typical t(9;22)(q34;q11) and the molecular biology study showed the p210 rearrangement (b2a2)...
متن کاملPrognostic significance of additional cytogenetic abnormalities at diagnosis of Philadelphia chromosome-positive chronic granulocytic leukemia.
Of 661 patients with Philadelphia chromosome (Ph)-positive, nonblastic chronic granulocytic leukemia, 58 had cytogenetic abnormalities in addition to the Ph at the time of diagnosis. Twenty patients had reduplication of the Ph in one or more metaphases. Twenty-one patients with a single Ph exhibited hyperdiploidy in one or more metaphases. Eleven patients had two or more hypodiploid metaphases ...
