  • Epidemiology and Risk Factors of Chronic Myeloid Leukemia
      • Epidemiology and Risk Factors
      • True or False: Patients with CML may initially have symptoms of weight loss, low-grade fever, night sweats, or no symptoms at all.
      • True or False: CML is only a disease of children and is rarely seen in adults.
      • Which of the following options best describes CML?
  • Site of Involvement and Clinical Features for CML
      • Sites of Involvement and Clinical Features
      • True or False: CML patients in CP commonly present with very low WBC and platelet counts.
      • True or False: Splenomegaly is common in the CP of CML.
  • Peripheral Blood, Blood Smear and Bone Marrow Morphology
      • Morphology of the Peripheral Blood Smear
      • Morphology of the Bone Marrow Aspirate Smear

      • Cytochemical Staining, continued
      • True or False: Leukocyte alkaline phosphatase activity (LAP score) is very strong in CML and weak in leukemoid reaction.
      • True or False: Immunophenotyping is very valuable in BP to distinguish myeloid, lymphoid, or mixed phenotype blasts.
  • Differential Diagnosis
      • Differential Diagnosis
      • True or False: Patients with CML and leukemoid reaction present with leukocytosis.
      • True or False: CML resembles a leukemoid reaction in many ways and is usually resolved with antibiotics.
