Precursor T-cell acute lymphoblastic leukemia/lymphoblastic lymphoma and acute biphenotypic leukemias.
Session 4 of the 2005 Society of Hematopathology/European Association for Haematopathology Workshop focused on case presentations of precursor T-cell acute lymphoblastic leukemia/lymphoblastic lymphoma (pre-T ALL/LBL) and acute biphenotypic leukemia. Pre-T ALL represents approximately 15% of childhood and 25% of adult ALL cases. Pre-T LBL comprises 85% to 90% of LBL and frequently manifests as ...
متن کاملEarly T-cell Precursor Acute Lymphoblastic Leukemia/Lymphoma.
Discrete diagnostic subtypes of T lymphoblastic leukemia/lymphoma (T-cell acute lymphoblastic leukemia/lymphoma, T-ALL) have historically not been widely recognized. Recently, a novel subset with distinctive immunophenotypic, molecular, and clinical features has been proposed. Termed early T-cell precursor acute lymphoblastic leukemia (ETP-ALL), these cases seem to correspond to a very early st...
متن کاملT-cell Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma
T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL) are neoplasias of immature T-cell precursors considered as a unique biological entity in the 2008 World Health Organization Classification of Hematologic Neoplasias1. Both entities are arbitrarily separated by a cut-off point of 20%-25% of blast cells in the bone marrow. There is a general agreement that T-ALL ...
متن کاملCytosine arabinoside transport and metabolism in acute leukemias and T cell lymphoblastic lymphoma.
Cytosine arabinoside (araC) has proven efficacy in acute myeloid leukemia (AML), but its place in the treatment of acute lymphoblastic leukemia (ALL) and T lymphoblastic lymphoma is uncertain. The therapeutic potential of araC has been assessed in patients with AML, ALL, and T lymphoblastic lymphoma by measuring the conversion of araC to its active metabolite, the 5'-triphosphate of araC (araCT...
متن کاملPrimary laryngeal manifestation in precursor T-cell acute lymphoblastic leukemia
Primary involvement of the larynx in non-Hodgkin's lymphoma (NHL) is rare. Early symptoms are non-specific and thus, it is difficult to diagnose. In the present study, the case of a 52 year-old male with hoarseness due to diffuse T-cell lymphoma as the first manifestation of precursor T-cell acute lymphoblastic leukemia is presented. Subsequent to treatment with three cycles of the etoposide an...
