title: Sudan black B positivity in acute lymphoblastic leukemia.
abstract: The records of 458 patients with acute lymphoblastic leukemia (ALL) have been reviewed. The diagnosis of ALL was based on clinical examination and morphological, cytochemical and immunophenotypic characteristics (20% or more blasts reacting with lymphoid monoclonal antibodies) of blood and/or bone marrow. Blast cells of 6 (1.3%) patients showed positive reaction with Sudan black B (SBB) in the absence of reactivity to any other myeloid markers. Positive reaction with SBB stain cannot be considered specific for myeloid series.
