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 کاملB-acute lymphoblastic leukemia/lymphoblastic lymphoma.
OBJECTIVES This session of the 2013 Society of Hematopathology/European Association for Haematopathology Workshop was dedicated to B-acute lymphoblastic leukemia (B-ALL)/lymphoblastic lymphoma (LBL) with recurrent translocations and not otherwise specified. METHODS In this review, we summarize the cases discussed during the workshop, review the pertinent and most recent literature on the resp...
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...
