Which hematological disorder is characterized by the presence of excess immature leukocytes?

• A. Thrombocytopenia
• B. Leukemia
• C. Anemia
• D. Myeloma

Answer: (B)

Leukemia is specifically characterized by the overproduction of immature leukocytes, also known as blasts. In this disorder, there is a malfunction in the bone marrow where the normal process of hematopoiesis becomes disrupted, leading to an accumulation of these immature cells in the blood and bone marrow. This excess of immature leukocytes can impair the production of normal blood cells, resulting in a variety of symptoms such as fatigue, increased infections, and bleeding due to the lack of functional leukocytes, red blood cells, and platelets. Thrombocytopenia refers to a low platelet count, not an increase in immature leukocytes. Anemia is characterized by a deficiency in red blood cells or hemoglobin and is associated with symptoms of fatigue and weakness but does not involve the proliferation of immature leukocytes. Myeloma, particularly multiple myeloma, involves plasma cells and does not typically lead to an increase in immature leukocytes; rather, it results in abnormal proliferation of antibody-producing plasma cells. Thus, the presence of excess immature leukocytes is a hallmark sign that distinctly identifies leukemia as the correct choice in this context.
