Write answer in between .Q:A 59-year-old man comes to the physician because of worsening fatigue and a 1-week history of gingival bleeding. He has also had decreased appetite and a 5-kg 11-lb weight loss over the past month. He has tried over-the-counter vitamin supplements with no relief of his symptoms. He appears pale. His temperature 37.8 C 100.0F, pulse is 72min and blood pressure is 12070 mm Hg. Physical examination shows numerous petechial lesions over the upper and lower extremities. A bone marrow smear is shown. Which of the following additional findings is most likely in this patient?? A: Translocation t9;22, B: Positive heterophile antibody test, C: Peroxidase-positive granules, D: Cold agglutinin antibodies, E: Follicular hyperkeratosisn,  <response>: Based on the patients symptoms of fatigue, gingival bleeding, decreased appetite, weight loss, and petechial lesions, this appears to be a case of acute leukemia. The bone marrow smear would be key to narrowing down the specific diagnosis. Choice A describes the Philadelphia chromosome translocation seen in chronic myelogenous leukemia CML, which is unlikely with the acute presentation here. Choice B describes infectious mononucleosis, which does not match this patients symptoms.Choice C describes myeloperoxidase staining of granules, which would be consistent with acute myeloid leukemia AML. This is a likely finding.Choice D describes cold agglutinin antibodies seen in cold agglutinin disease, which does not match this presentation. Choice E describes skin findings of follicular hyperkeratosis seen in mycosis fungoides, a type of cutaneous T cell lymphoma. This does not match the patients symptoms.Therefore, choice C of peroxidase-positive granules is the most likely additional finding in this patient, consistent with a diagnosis of acute myeloid leukemia.C: Peroxidase-positive granules
