Acute promyelocytic leukaemia (APL) is characterized cytogenetically by t(15;17)(q22:q21) which results in the production of a PML/RAR alpha fusion protein. Detection of the translocation or the fusion gene product is required for objective diagnosis of APL. This can be accomplished by conventional cytogenetic methods, fluorescence in situ hybridization or RT-PCR. ...
Langabeer S E - - 1997
Acute myeloid leukaemia (AML) with the t(8;21)(q22;q22) is deemed to be a 'good-risk' disease. 396 patients with AML at diagnosis were screened for the presence of t(8;21) and AML1/ETO fusion transcripts by cytogenetic and RT-PCR techniques respectively. 32 cases of t(8;21) were detected, all of which were also PCR positive. ...
Handa R - - 1997
We report a patient with acute lymphoblastic leukemia, who presented with pericardial effusion. There was no haematologic evidence of leukemia at the time of presentation. The pericardial effusion resolved with chemotherapy. Although a common finding at autopsy, clinically evident pericardial effusion is rare in leukemia. It is also extremely rare ...
Beverstock G C - - 1997
Tetrasomy 8 is a rare form of acquired aneuploidy found exclusively in the myeloid leukemias. Hexasomy 8 is even rarer: only one case has been reported, thus far. We describe here the second case of hexasomy 8 as the sole abnormality in an elderly female patient with myelodysplastic syndrome (MDS).
Mok T - - 1997
We report here a case of fatal Penicillium citrinum infection. The patient, who suffered from acute myeloid leukemia, developed signs and symptoms typical of fungal pneumonia and pericardial tamponade after undergoing standard induction chemotherapy. Despite attaining complete remission of her leukemia, the patient succumbed 8 weeks after presentation. At autopsy, ...
Colombo AL - - 1997
A fatal case of Rhodotorula glutinis fungemia in an 11-year-old boy with acute lymphoblastic leukemia undergoing third reinduction chemotherapy is reported. This is the first case of fungemia by Rhodotorula glutinis reported in Brazil.
Kamble R - - 1997
Localized extramedullary collection of leukemic cells is termed as granulocytic sarcoma. Incidences of 2-8% in acute myeloid leukemia have been reported in various autopsy studies. In female it usually involves ovary. Since most of such tumors are asymptomatic, they are detected only at autopsy. We report here a case who ...

Allogeneic BMT offers the possibility of cure for a variety of hematopoietic malignancies, but disease relapse remains a major cause of treatment failure. This report describes two cases in which flow cytometric cell sorting (FACS) and molecular chimerism analysis were combined to increase the sensitivity of minimal residual disease (MRD) ...
Miller K - - 1997
Central nervous system involvement in chronic lymphocytic leukemia is rare. We describe a patient with early stage chronic lymphocytic leukemia who developed visual loss and transient paresthesias. Lumbar puncture with cytology and flow cytometry documented leukemic meningitis, which responded to standard treatment; including cranial irradiation and intrathecal chemotherapy. We review ...
Juneja S - - 1997
Some cases of hypereosinophilic syndrome and myeloproliferative disorders exhibit common features and thus pose diagnostic and therapeutic problems. We describe a 68-year-old patient who presented with such features and developed lytic lesion in the tibia. Based on our case and a review of literature we suggest that cases like ours ...
Rund D - - 1997
Hyperploidy is a rare finding in leukemias, with isolated cases of tetraploidy reported in acute myeloblastic and acute lymphblastic leukemias. We report the first case of acute myeloid leukemia with near-pentaploidy (5 n+/-) which was present in 100% of metaphases at diagnosis. By light microscopy, the leukemic blasts were exceptionally ...
Ma S K - - 1997
Three consecutive cases of pediatric myelodysplastic syndrome (MDS) diagnosed over a three-year period in Queen Mary Hospital, Hong Kong, were described. Depending on the classification system used, they comprised two cases of chronic myelomonocytic leukemia (CMMoL) of which one can be reclassified as juvenile chronic myeloid leukemia (JCML) and one ...
Misialek M J - - 1997
There exists a great deal of overlap between many myelodysplastic syndromes and myeloproliferative disorders. This is most evident in the spectrum of disorders classified under the term chronic myeloid leukemia. These include chronic granulocytic leukemia, atypical chronic myeloid leukemia and chronic myelomonocytic leukemia. Current classification often does not clearly separate ...
Pasqualetti P - - 1997
A case of monoclonal gammopathy of undetermined significance (MGUS) which evolved directly into primary plasma cell leukemia (PCL) is reported. Even if MGUS and PCL represent the opposite aspects of the same immunoproliferative disorder, no previous cases of this direct evolution have been described, as stated by an accurate review ...
Aken'Ova Y A - - 1996
Neurological manifestations occur in about one-quarter of patients with chronic myelogenous leukaemia (CML), usually as a result of hyperleukocytosis, predisposing to intravascular thrombus formation. We report the clinical and pathological findings in a 16-year-old female with CML who presented with deafness, blindness and paraplegia, and discuss possible aetiopathogenetic mechanism.

We describe t(8;16)(p11;p13) acute myeloid leukaemia (AML-M4) in a 12-year-old white male with a history of prenatal X-ray exposure. He had skin and bone involvement and some of the leukaemic blasts showed haemophagocytosis, characteristic features seen in t(8;16) AML. 20% of the reported cases of t(8;16)(p11;p13) AML are therapy-related and ...
Pearson L - - 1996
Resistance to chemotherapy is a major problem in acute myeloid leukemia (AML). An important resistance mechanism in adult AML is active drug efflux mediated by the multidrug resistance protein-1 (MDR1). To determine if MDR1 is important in childhood AML, we examined MDR1 expression and functional dye/drug efflux in 20 pediatric/adolescent ...
Batanian J R - - 1996
We report a case of childhood acute mixed lineage leukemia (AMLL) with a translocation t(6;14)(q25;q32) as the main clonal abnormality. A comparison of this case with another one with similar cytogenetics and clinical findings may suggest that t(6;14)(q25;q32) is a non-random occurrence in childhood AMLL.
Beverstock G C - - 1996
The detection of isochromosomes in the leukemias and in solid tumors has been well described in the literature, the most common being the i(17q), which is found in the blast crisis of CML and terminal stages of acute myeloid leukemia. Reports of isochromosome 7 have, however, been less well represented, ...
Nagai K - - 1996
In order to establish diagnostic criteria for hypocellular acute leukemia (HL), we have reviewed 32 cases selected on the basis of hypothetical 40% or less cellularity, by focusing on morphology, immunophenotype, karyotype and response to low dose Ara-C (LDAC) regimen and compared them with 40 cases of myelodysplastic syndrome (MDS) ...
Tekkök I H - - 1996
We report the case histories of identical twin brothers who developed concordant acute lymphoblastic leukemia at the age of 4 years and who later developed leukoencephalopathy and hydrocephalus related to central nervous system prophylaxis by, in the first case intrathecally administered methotrexate and, in the second by intrathecally administered methotrexate ...

During the immunodiagnosis of 517 cases of acute myelogenous leukemia (AML) entered into the Medical Research Council (MRC) AML 10 trials, we have observed the CD34 precursor cell antigen more frequently in AML of M2 morphology, especially in the 84% of cases with the t(8;21) chromosomal translocation, than in any ...
Deb G - - 1996
We present a case report of a child who developed acute lymphoblastic leukemia, neurofibromatosis, optic glioma, and xanthogranulomatosis. This complex is unusual, not previously described, and appears to be a coincidence of different diseases. The importance of this case is that it may offer a clue to the genetic base ...
Lanza C - - 1996
Acute leukemias carrying MLL rearrangements are characterized by a high degree of clinical and immunologic heterogeneity, as demonstrated by variability in their immunophenotype, consistent with lymphoid or myeloid/monoblastic derivation, as well as their occurrence in distinct age groups from infancy to adulthood. Recently, it was shown that inactivation of the ...
Mody G M - - 1996
The rheumatologic manifestations of hemophilia and the hemoglobinopathies have been previously reviewed. Recent observations on the management and complications of these disorders are presented. Although rheumatologic manifestations are well recognized in leukemias and lymphomas, most of the observations have been based on small series of patients and case reports. This ...

1.286 patients were diagnosed as DIC, among 123.231 patients who were admitted in the 285 departments of the university hospitals in Japan, in 1992. The incidence of DIC was high in acute promyelocytic leukemia, fulminant hepatitis, abruptio placentae, acute respiratory distress syndrome, and sepsis. In cases of DIC, bleeding tendency ...
Patiño-Sarcinelli F - - 1996
Leukemias of megakaryocytic lineage are rare and heterogeneous clinical entities. The nomenclature published in the literature is confusing and perhaps inappropriate to designate these primary myeloproliferative disorders. We describe a patient with essential thrombocythemia who evolved through myelofibrosis and myeloid metaplasia to a final picture of leukemia with megakaryocytic differentiation ...
Crisan D - - 1996
The bcr gene rearrangement resulting from the Philadelphia translocation is diagnostic of chronic myelogenous leukemia (CML) and is considered the hallmark of this myeloproliferative disorder (MPD) at the molecular level. The other MPDs, essential thrombocythemia (ET), polycythemia vera (PV), agnogenic myeloid metaplasia (AMM), and unclassified MPD, share morphologic features with ...
Michaux L - - 1996
Translocation (Y;1)(q12;q12) is a rare cytogenetic anomaly occurring in hematologic disorders thought to affect stem cells. We report here on two new cases, one end-stage myelofibrosis and one chronic myelomonocytic leukemia. The translocation breakpoints were assessed by conventional cytogenetic techniques in both cases and by FISH in the second case. ...
Dunphy C H - - 1996
Acute myelofibrosis (AMF), as defined by an acute panmyelopathy associated with marked megakaryocytic hyperplasia and marrow fibrosis, appears to be a stem cell disorder. Even though it is most difficult to distinguish from various myeloproliferative and myelodysplastic disorders as well as acute myelogenous leukemia, it has rarely been reported to ...
Maj J S - - 1996
In our report, myelofibrosis in children is discussed and two cases of acutely developing myelofibrosis in association with acute megakaryoblastic leukaemia (M7) are presented. In the first case (girl, 34 months), it was acute myelofibrosis of hypocellular marrow. Diagnosis of M7 was confirmed by positive reaction of blasts from peripheral ...
