A 42-year-old man is feeling chronically fatigued. His hemoglobin is 11.5 g/dL, and the blood film is hypochromic and microcytic. The serum iron is increased, total iron-binding capacity (TIBC) is normal, ferritin is increased, and HbA2 is decreased.For the above patient with a hypochromic microcytic anemia, select the most likely diagnosis.: (A) iron deficiency anemia, (B) beta-thalassemia trait, (C) anemia of chronic disease, (D) sideroblastic anemia
Answer is D. Sideroblastic anemia is associated with an increased serum iron and ferritin. TIBC is generally normal. HbA2 is usually decreased.
