Iron deficiency AnemiaHereditary spherocytosisMegaloblastic anemiaThalassemia minorSideroblastic anemia

An anemic patient is found to have hypochromic, microcytic red cells. Additional tests reveal the serum iron levels, the total iron-binding capacity, and the transferrin saturation to be reduced. A bone marrow biopsy reveals the iron to be present mainly within macrophages. Which of the following is the most likely diagnosis?

A 3 year old boy is being evaluated for sudden onset of bleeding episodes. The total WBC count is 68,000, 77% of which are homogeneous cells with nuclei having immature chromatin. Further testing of the immature cells show:

T dT: positivePAS: positiveAcid phosphatase: positiveMyeloperoxidase: negative

Based on these findings, which of the following is the cell of origin of these immature cells?

MyeloblastsMonoblastsMegakaryoblastsLymphoblastsErythroblasts

A 65 year old man with enlarged axillary lymph nodes. Biopsy reveals effacement of the normal lymph node architecture by a diffuse proliferation of small, normal-appearing lymphocytes. These same cells are present in the peripheral blood. A bone marrow biopsy reveals a diffuse proliferation of these small lymphocytes. Special stains reveal these cells to be positive for CD5 and CD23. Which of the following is the best classification for this lymphoma?

Burkitt lymphomaFollicular non-Hodgkin lymphomaNodular sclerosis Hodgkin lymphomaMixed cellularity Hodgkin lymphomaSmall-lymphocytic non-Hodgkin lymphoma

A 23-year-old female presented with painless swelling on the right side of the neck: she also complained of dyspnea following moderate exercise in the few weeks prior to her visit. Her past and recent medical histories were fine and no other remarkable co-morbidities were reported. She had a 3-year-old daughter and was employed in a grocery store.

The patient did not report any systemic symptoms including night sweats, weight loss or fever. The physical examination confirmed the presence of bilateral fixed lymph nodes of hard consistency in the latero-cervical and supraclavicular area with an estimated size of 1.5 cm and without the evidence of any other superficial lymphadenopathy or organomegaly.

Her biopsy findings are provided. Which of the following is most characteristic of this disorder ?

(A) Benign neoplasm

(B) Frequent association with EBV

(C) Mostly a complication of HIV

(D) Peak incidence in early childhood

(E) Relatively favorable clinical course

An 18 year old African American man is brought to the emergency department with pain in the back and legs.

Which of the following is most likely to happen to the spleen?

• Enlarged with congestion• Enlarged with malignant cell infiltration• Enlarged with white pulp hyperplasia• Normal• Atrophic

A 4 year old girl develops jaundice and pallor. Laboratory studies show anemia, reticulocytosis and increase indirect bilirubin. The peripheral blood smear is shown. Which additional finding is most likely to be present in this case?

• Decreased LDH• Increased Haptoglobin• Increased MCHC• Increased MCV• RBC inclusions
