Bone marrow aspirate from a patient with AML (FAB classification M0). (Wright-Giemsa stain). The blasts lack differentiating features and were nonreactive to Sudan Black B and myeloperoxidase staining. More than 20 percent of the blasts expressed myeloid antigens CD13 and CD33. The blasts were terminal transferase negative and nonreactive with antibodies to lymphocytes. Auer rods were not found.
