Double Lineage Switch from Acute Megakaryoblastic Leukemia (AML-M7) to Acute Lymphoblastic Leukemia (ALL) and Back Again: A Case Report

Double Lineage Switch from Acute Megakaryoblastic Leukemia(AML-M7) to Acute Lymphoblastic Leukemia (ALL) and Back Again: A Case Report

A 39-year-old woman was diagnosed as having immune thrombocytopenia (ITP) in 1981 in another hospital, and she was well controlled with prednisolone. No other immunosuppressive drugs, such as cyclosporine or azathioprine, were used. In 1997, she was diagnosed as having acute megakaryoblastic leukemia (AML-M7) in another hospital. Blasts showed the absence of peroxidase (POX) and positive platel...

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...

Acute myelogenous leukemia switch lineage upon relapse to acute lymphoblastic leukemia: a case report

Acute leukemia, the most common form of cancer in children, accounts for approximately 30% of all childhood malignancies, with acute lymphoblastic leukemia being five times more frequent than acute myeloid leukemia. Lineage switch is the term that has been used to describe the phenomenon of acute leukemias that meet the standard French-American-British system criteria for a particular lineage (...
