nicious anemia and polycythemia, or of pernicious anemia and acute myeloblastic leukemia, is extremely rare. Wintrobe’ notes only four instances imi which pernicious anemia preceded the onset of acute myeloblastic leukemia. Polycythemia following pernicious anemia is of equal rarity.’ ‘ 2 On the other hand, the emergence of acute leukemia in cases of polycythemia, while uncomiimon, is miot as r...

Arginine-rich and lysine-rich histones were extracted from various cytologic types of leukemic blasts and from preparations rich in normal monocytes. On polyacrylamide disc electrophoresis, the patterns of normal monocyte histones closely resembled those found in acute histiomonocytic leukemia (Schilling type). The electrophoretic patterns of histones obtained from leukemic blasts in acute myel...

Background: Previous studies have pointed to the major role of viruses in pathogenesis cancers, especially lymphoproliferative cancers. Objectives: The current study investigated relationship between recent Human Herpesvirus Type 6 (HHV6) infection and childhood leukemia-lymphoma syndrome. Methods: From January 2011 December 2012, we entered every new case acute lymphoblastic leukemia, non-Hodg...

Acute myeloblastic leukemia accounts for approximately 20% of acute leukemias in children. The days the microscope represented the main tool in the diagnosis and classification of Acute Myeloblastic Leukemia seem to be very far. This review summarizes the current diagnosis of this malignancy, where the morphological, cytochemical, immunophenotyping, cytogenetic and molecular characterization re...

Acute myeloid leukemia is not a single disease but a group of neoplastic disorders. The malignant cells gradually replace, and inhibit the growth and maturation of, normal erythroid, myeloid, and megakaryocytic precursors. Included among the names for this condition are acute myelogenous leukemia, acute myelocytic leukemia, acute myeloid leukemia, acute myeloblastic leukemia, acute granulocytic...

Acute acalculous cholecystitis is a rare complication in the treatment of acute myeloblastic leukemia. Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastri...

white cells could have been studied. The white cell counts on the next two occasions were also low, being 3000 and 4350 cu./mm. respectively, the latter in June 1962, but when she was admitted this time in May 1964 the picture was that of acute myeloblastic leukemia. This was a rare presentation of acute myeloblastic leukemia, this diagnosis should be considered as a possibility Whenever one is...

Blast cells were obtained from 17 patients with acute undifferentiated leukemia and 13 patients with chronic myelogenous leukemia in blast crisis. The blasts were tested with anti-i serum in cytotoxicity tests and with antisera to myeloblastic leukemia-associated antigens in immunofluorescence tests. The terminal deoxynucleotidyl transferase (TDT) content of the blasts was also measured. Lympho...
