Morphologic features and results of CGH array of an acute myeloid leukemia patient with a clonal translocation t(11;12)(p15;q13) resembling the classical hypergranular subtype of acute promyelocytic leukemia. May-Grümwald-Giemsa–stained bone marrow smear (1000×, Nikon Eclipse 80i microscope and Nikon DS-Fi 1 camera) showing (A) promyelocytes with hypergranulated cytoplasm; several nuclei are invaginated and (B) promyelocyte with bundles of Auer rods (faggot cell). (C) Representative karyotype of BM cells with t(11;12)(p15;q13). (D) Results of CGH array. Top, microdeletions in chromosome 11p15 involving the NUP98 gene. Bottom, microdeletions in chromosome 12q13 involving the RARG gene.
