Myeloid/lymphoid neoplasms with FGFR1 rearrangement (MLN-FGFR1) comprise a heterogeneous group of that can present as myeloproliferative neoplasm, myelodysplastic/myeloproliferative acute myeloid leukemia, T or B lymphoblastic leukemia/lymphoma, mixed phenotype leukemia. The overall outcome these is poor, and patients often show cytogenetic evolution gain additional chromosomal abnormalities le...

background: acute lymphoblastic leukemia (all) is the most common form of childhood cancer leading to cancer-related death in children. most infants with all harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. mixed-lineage leukemia-rearrangement (mll-rearrange...

The 2008 World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues introduced a new category for myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1. Many of these cases present as a myeloproliferative neoplasm, usually with eosinophilia. However, neoplasms associated with rearrangement of PDGFRA can present as acute...

conclusions to our knowledge, this is the first chronic case confirmed by the prolonged presence of hev rna in china. it is also the first reported persistent hepatitis e infection caused by hev genotype 4. case presentation here we report a chinese boy with acute lymphoblastic leukemia, who developed hepatitis e during a period of intensive chemotherapy. twenty months after the initial infecti...

abstract background leukemia is the most prevalent childhood cancer and acute lymphoblastic leukemia (all) constitutes 75% of all cases. the most frequent presenting symptoms are fever, weight loss and pallor. early detection of clinical symptoms positively affects timely diagnosis. the objectives of the present study were to assess frequency of presenting symptoms, laboratory data, immune phen...

midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. herein, we describe a case of acute pre b cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. at the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. our case sugg...

Tyrosine kinase inhibitors have profoundly modified the treatment and prognosis of chronic myeloid leukemia and Ph(+) acute lymphoblastic leukemia. A rapid and accurate detection of the BCR-ABL fusion protein is paramount today for an optimal management of Ph(+) acute lymphoblastic leukemia. We have utilized a recently described and commercialized immunoassay that identifies qualitatively the p...

acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. the conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. it has been rarely reported in the literature. in leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. herein, we rep...

Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...
