Pancytopenia is a major risk associated with which condition?

• A. Aplastic anemia
• B. Myelodysplastic syndrome
• C. Chronic leukemia
• D. Thalassemia

Answer: (B)

Pancytopenia means low red cells, white cells, and platelets, signaling a problem in the bone marrow that affects all blood lineages. In myelodysplastic syndrome, the marrow contains dysplastic, ineffective hematopoietic cells that fail to mature properly, leading to reduced production of all three cell types. That makes pancytopenia a common and important feature, which explains why patients are at higher risk for infections (due to low white cells), bleeding (due to low platelets), and fatigue from anemia (low red cells). While other conditions can cause cytopenias, myelodysplastic syndrome is classically associated with this broad suppression of blood cell production and carries a notable risk of progression to acute leukemia, reinforcing why pancytopenia is a key clue in its diagnosis.
