case_images: Bone marrow aspirate (1000x) using wright stain and chromosome study on first admission. (A) A BM study revealed acute myeloid leukemia. (B) A chromosome study revealed a karyotype of 46, XY, t(9; 22)(q34; q11) in all 20 cells analyzed.

case_images: A BM study (Figure 1) revealed hypercellular marrow with 25% blasts (Table 1). A chromosome study revealed a karyotype of 46, XY, t(9; 22)(q34; q11) in all 20 cells analyzed (Figure 1).
case_images: Immunophenotyping by flow cytometry of the blasts at acute myeloid leukemia phase.

case_images: Immunophenotyping by flow cytometry suggested that the blasts were positive for cytoplasmic myeloperoxidase (MPO), CD4, CD11b, CD15, CD16, CD33, CD34, CD38, CD56, and CD71 (Figure 2).
case_images: Bone marrow aspirate (1000x) using Wright stain and chromosome study on second admission. (A) A BM study revealed acute B-lymphoid leukemia. (B) A chromosome study revealed a karyotype of 46, XY, t(9; 22)(q34; q11) in all 20 cells analyzed.
