LEUKEMIA Dr. Omar Alshaer

Acute Leukemia

 1/ A 40-year-old woman complains of fatigue and nausea of 3 months in duration. Physical examination reveals numerous pustules on the face, as well as splenomegaly and hepatomegaly. Laboratory studies show hemoglobin of 6.3 g/dL and platelets of 50,000/mL. A peripheral smear shows malignant cells with Auer rods. The patient develops diffuse purpura, bleeding from the gums, and laboratory features of disseminated intravascular coagulation (DIC). Which of the following is the appropriate diagnosis?  (A) Acute lymphoblastic leukemia  (B) Acute megakaryocytic leukemia  (C) Acute promyelocytic leukemia  (D) Chronic myelogenous leukemia

Acute Leukemia  3/ A 6-year-old boy presents with fatigue, fever, and night sweats. Physical examination reveals marked pallor. Palpation of his sternum demonstrates diffuse tenderness. Laboratory studies disclose anemia, thrombocytopenia, and leukocytosis. The WBC differential count shows that 90% lymphoid blasts.

Chronic Leukemia  A- Acute 5/ A 60-year-old man complains of night sweats, weight loss, easy fatigability, and discomfort in the left upper abdominal quadrant. Physical examination reveals splenomegaly. Laboratory studies show leukocytosis (40,000/mL). A peripheral blood smear demonstrates mature and maturing granulocytes, myelocytes, basophils, and occasional myeloblasts. The bone marrow is hypercellular and dominated by WBC precursors. Megakaryocytes are numerous, and RBC precursors are less prominent. Cytogenetic studies disclose a monoclonal population of abnormal cells with a t(9;22) chromosomal translocation. What is the appropriate diagnosis?  lymphoblastic leukemia  B- Acute myeloid leukemia  C- Chronic lymphocytic leukemia  D- Chronic myeloid leukemia
