She has no history of any significant illness and takes no medications. Her vital signs are within normal limits. On percussion, the spleen size is 15 cm 5.9 in. Otherwise, the physical examination shows no abnormalities. The laboratory test results are as follows:Hemoglobin 10 gdLMean corpuscular volume 88 μm3Leukocyte count 65,000mm3Platelet count 500,000mm3Two images of the peripheral blood smear are shown. Laboratory studies are most likely to show which of the following?? A: Auer rods, B: Cluster of differentiation 20 CD20, C: JAK2 mutation, D: Philadelphia chromosome, E: Translocation between chromosomes 15 and 17,  <response>: This is a clinical vignette describing a 54-year-old woman with left upper quadrant abdominal discomfort, fatigue, splenomegaly, anemia, thrombocytosis, and leukocytosis based on lab results. The peripheral blood smear images show abnormal white blood cells with Auer rods, which are rod-shaped inclusions commonly seen in myeloid leukemic blasts. The findings are most consistent with chronic myeloid leukemia CML, which is characterized by the Philadelphia chromosome - a translocation between chromosomes 9 and 22. This leads to constitutive activation of the tyrosine kinase BCR-ABL. JAK2 mutation is associated with myeloproliferative neoplasms but not CML. CD20 is expressed in B cell lymphomas. The translocation between chromosomes 15 and 17 is found in acute promyelocytic leukemia.D: Philadelphia chromosome
