Koilonychia is also known as spoon nails and is associated with what anemia?

Explanation:
Koilonychia indicates long-standing iron deficiency. The spoon-shaped nails reflect impaired nail bed growth when iron stores are depleted, making iron-deficient anemia the best fit. The other anemias don’t typically present with this nail change: sideroblastic anemia involves abnormal iron handling with ring sideroblasts, megaloblastic anemia stems from B12 or folate deficiency, and aplastic anemia causes bone marrow failure with pancytopenia. So the nail sign specifically points to iron-deficient anemia.
