Sudan Black B

03/01/2013 - "In this study, we investigated whether or not a cut-off of 10% positivity for cMPO equally defines an acute leukemia as AML or MPAL as compared to a cut-off for cMPO of 20% and compared this with results obtained for Sudan Black B (SBB) staining by cytomorphology. "
08/01/1990 - "Conversely, occasional cases of Sudan black B-positive ALL can be confused with myeloblastic leukemia. "
06/01/2001 - "We propose following modified criteria for AML-M0: (1) standard criteria for acute leukemia; (2) undetectable or less than 3% MPO or Sudan black B staining in blasts; (3) lack of expression of lymphoid-specific antigens, cyCD3 for T lineage and cyCD79 and cyCD22 for B lineage; and (4) positivity for any of the myelomonocytic lineage antigens known not to be expressed on normal T or B lymphocytes or positivity for MPO as detected by ultrastructural cytochemistry, immunohistochemistry, or flow cytometry."
02/01/1993 - "In a series of 63 patients with newly diagnosed acute leukemia who were admitted to the Main Hospital of Nippon Medical School, five patients fit the criteria for AML-M0: negative myeloperoxidase (MPO) and Sudan black B reaction by light microscopy, negative for B- and T-lineage markers, and positive for myeloid markers. "
06/01/1979 - "The PAS, Sudan Black B and Peroxidase reactions have been very important in the differential diagnosis between lymphoblastic and myeloblastic acute leukemias. "

07/01/1994 - "Leukemic blasts in the majority of cases shared unique morphologic features (deeply invaginated nuclear membranes, scant cytoplasm with fine azurophilic granularity, and finely granular Sudan black B and myeloperoxidase cytochemical reactivity) that were remarkably similar to those of acute promyelocytic leukemia (APL); particularly the microgranular variant (FAB AML-M3v). "
02/01/1991 - "Cytochemical studies including peroxidase, sudan black B and esterases were used for staining peripheral blood and bone marrow smears from 42 patients with acute promyelocytic leukemia. "
05/01/2002 - "Negative stain for myeloid peroxidase and Sudan black B in acute promyelocytic leukemia (APL) cells: report of two patients with APL variant."

10/01/2017 - "In this study, we show that the depletion of functional complement activity at the time of the initiation of zymosan-induced arthritis, significantly reduced the expression of TGF-beta1/3, BMP2 and pSmad2 and decreased the number of Sudan Black B positive cells in the synovium. "

07/01/2004 - "Sudan Black B Positive Acute Lymphocytic Leukemia."
01/01/1992 - "A total of 146 patients with newly diagnosed acute lymphoblastic leukemia (ALL) occurring over a 9 1/2-yr period were reviewed; four of these patients (2.7%) had blast cells that stained positively with Sudan Black B. "
01/01/1992 - "Sudan black B positivity in acute lymphoblastic leukemia."
06/01/1989 - "[Sudan black B-positive acute lymphoblastic leukemia]."
01/01/1988 - "Sudan black B positivity in acute lymphoblastic leukemia."

12/01/1985 - "While light microscopy morphology was suggestive of acute myeloid leukemia M5a and light microscopy cytochemistry showed 80% of blasts to be strongly positive with Sudan Black B--more consistent with a diagnosis of M4--ultrastructural analysis demonstrated that the predominant cells were promyelocytes with immature primary granules hardly visible with the Romanovsky stains by light microscopy. "
07/01/1984 - "The presence of greater than 3% Sudan black B (SBB) positivity in leukaemic blasts has been considered diagnostic of acute non-lymphocytic leukaemia (ANLL). "
07/01/1991 - "By light microscopic and ultrastructural criteria, these structures closely resembled Auer rods found in acute myeloid leukemia; however, the authors could not find cytochemical evidence of lysosomal origin (results were negative for myeloperoxidase, Sudan black B, acid phosphatase, and periodic acid-Schiff). "
01/01/1984 - "The blasts met immunological criteria for acute lymphoblastic leukaemia (ALL)--common ALL antigen+, HLA-DR+, terminal deoxynucleotidyl transferase+--but their cytochemical features, including positive myeloperoxidase and Sudan black B, were those of acute nonlymphoblastic leukaemia (ANLL) as defined by the French-American-British Group.
