A novel chromosomal abnormality t (9;14)(p24;q13) in B-acute lymphoblastic leukemia

MYC Rearrangement Involving a Novel Non-immunoglobulin Chromosomal Locus in Precursor B-cell Acute Lymphoblastic Leukemia

MYC rearrangement, a characteristic cytogenetic abnormality of Burkitt lymphoma and several subsets of other mature B-cell neoplasms, typically involves an immunoglobulin gene partner. Herein, we describe a case of precursor B-cell lymphoblastic leukemia harboring a MYC rearrangement with a novel non-immunoglobulin partner locus. The patient was a 4-yr-old Korean boy with ALL of the precursor B...

DETERMINATION OF A SHARED EPITOPE ON CELLS FROM ACUTE MYELOGENIC LEUKEMIA (AML) AND T-ACUTE LYMPHOBLASTIC LEUKEMIA ( T-ALL)

Two IgM monoclonal antibodies (MAb) with strong reactivity for granulocytes and to a lesser extent for lurkat cell lines were established by immunizing BALBI c mice with a histiocytic cell line (UY37). These two MAbs (designated as 6C9 and 4C4) reacted with blast cells of T-acute lymphoblastic leukemia (T-ALL) and acute myelogenous leukemia (AML) patients as well as leukemic cells from pat...

Prolonged Vincristine Toxicity Induced by Concurrent Posaconazole in a Child with T-cell Acute Lymphoblastic Leukemia

Persistent Hypoplastic Acute Promyelocytic Leukemia with a Novel Chromosomal Abnormality of 46, XY, t(15;17), t(9;11)(q13;p13).

A diagnosis of acute promyelocytic leukemia (APL) is usually made when normal hematopoietic cells are substituted by APL cells. We encountered a unique APL patient who presented with persistent hypoplastic features of APL. An 84-year-old man presented with leukopenia (2.2 × 10(9)/L) and anemia (Hb 12.5 g/dL). Five months later, the bone marrow (BM) was hypoplastic with a normal proportion of bl...
