A 55 year old male presents with pallor and easy fatigability. Physical exam showed massive splenomegaly. CBC showed marked leukocytosis, and a peripheral smear showed numerous neutrophils, metamyelocytes, and myelocytes. SEE SLIDE 12.24. Basophils are also seen. A bone marrow aspirate shows a similar picture. This man likely has (A) a BCR-ABL fusion gene (B) a JAK2 mutation (C) an 8:22 translocation (D) an 11:22 translocation

A self-limited disease of adolescents and young adults that is causd by B lymphocytotropic EBV characterized by fever, sore throat and generalized lymphadenitis, an increase of atypical lymphocytes in blood and an antibody and T cell response to EBV.
Infectious mononucleosis(TOPNOTCH)Robbins Basic Pathology, 8th Ed. p. 442
Intermediate-sized round lymphoid cells with 2-5 prominent nucleoli. High rates of proliferation and apoptosis are characteristic. Nuclear remnants phagocytosed by interspersed macrophages with abundant clear cytoplasm, “starry sky pattern” SEE SLIDE 12.13.
Burkitt lymphoma(TOPNOTCH)Robbins Basic Pathology, 8th Ed. p. 453
Patient with this disease has a tendency toward easy bruising and massive hemorrhage after trauma or operative procedures, and recurrent bleeding into the joints. Petechiae are absent. Patients have a prolonged PTT and normal PT.
Hemophilia A and B (Factor VIII and IX Ddeficiency) (TOPNOTCH) Robbins Basic Pathology, 9th ed. p. 663
Myeloid tumor arising from a pluripotent stem cell associated with mutatios of the BCR-ABL gene. If untreated, may progress to a blast crisis.
Chronic Myelogenous Leukemia(TOPNOTCH)Robbins Basic Pathology, 8th Ed. p. 467
A 5 year old male is observed by his mother to have tea-colored urine whenever he has infections. One particular episode of pneumonia required hospital admission, where the child developed jaundice also. A peripheral blood smear showed red cells with Heinz bodies, while other red cells had parts of their cytoplasm “plucked out”. SEE SLIDES 12.4 and 12.5. The child likely has a deficient enzyme required in the production of reduced glutathione, the gene for which is found on (A) X chromosome (B) Y chromosome (C) chromosome 21 (D) chromosome 22
X chromosome (TOPNOTCH)Robbins Basic Pathology, 8th Ed. P 431-432
Condition caused by deletion of 1 alpha globin gene.
Silent carrier(TOPNOTCH)Robbins Basic Pathology, 8th Ed. p. 431
Tear drop cells are also called __________.
Dacrocytes(TOPNOTCH)Robbins Basic Pathology, 8th Ed. p. 440
An 8 year old child from the slums has easy fatigability and pallor. A peripheral blood smear shows large, egg-shaped red cell precursors, and hypersegmented neutrophils. SEE SLIDE 12.7. Short of measuring serum folate and vitamin B12 levels, what finding will suggest a vitamin B12 deficiency, rather than a folate deficiency? (A) gastrointestinal symptoms (B) neurologic symptoms (C) development of congestive heart failure (D) megaloblasts on bone marrow aspirate smears
neurologic symptoms (TOPNOTCH)Robbins Basic Pathology, 8th Ed. Pp 437-439
Subgroup of HL characterized by a large number of small resting lymphocytes admixed with a variable number of benign histiocytes. Variant RS cells described as multilobed, puffy nucleus Which appears like a “popcorn”. Excellent prognosis. SEE SLIDE 12.18.

Hodgkin Lymphoma (Presence of Reed-Sternberg cells) (TOPNOTCH)
A 2 y/o child arrived at well-child clinic. Mother reported that her child is exclusively breastfed for 6 months and then supplemented mainly by carrots. The patient is most likely prone to developing anemia caused by:
Vitamin B12 deficiency (TOPNOTCH)
Precipitates of denatured globin seen in RBC’s. SEE SLIDE 12.4.
