hyperchromatic macrocythemia

hy·per·chro·mat·ic mac·ro·cy·the·mi·a

an inexact term frequently used for macrocytes that contain an unusually large amount of hemoglobin, but are actually normochromic; although the total mass of hemoglobin is greater than normal (owing to the large cells), the percentage of hemoglobin in the cells is not greater than normal.
