Which of the following best describes aplastic anemia presentation?

• A. Polycythemia and splenomegaly
• B. Neutropenia and thrombocytopenia
• C. Elevated reticulocyte count and hypercellular marrow
• D. Increased white blood cell count and anisocytosis

Answer: (B)

Aplastic anemia is characterized by a significant decrease in the production of blood cells due to damage or failure of the bone marrow. This results in a deficiency of red blood cells, white blood cells, and platelets. In the context of the given options, neutropenia, which refers to a low white blood cell count, and thrombocytopenia, indicating a low platelet count, are classic presentations of aplastic anemia. Patients may present with symptoms related to these deficiencies, such as increased susceptibility to infections (due to neutropenia) and easy bruising or bleeding (due to thrombocytopenia). The lack of bone marrow response is reflected in lower than normal counts of these critical cell types. In contrast, other options provided do not align with the typical presentation of aplastic anemia. For example, polycythemia and splenomegaly are more indicative of other hematological conditions, while elevated reticulocyte count and hypercellular marrow suggest a bone marrow that is actively producing blood cells, which contradicts the findings in aplastic anemia. Increased white blood cell count and anisocytosis are also not characteristic of this condition; aplastic anemia typically features low white blood cell counts and uniformity in cell size due to hyp
