Red Cell Characteristics Related to Size

Pseudomacrocytes

Another type of macrocyte can be seen in the center of this slide. Notice it appears larger than the lymphocyte but in contrast to megalocytes has an area of central pallor. These macrocytes are sometimes referred to as "pseudo macrocytes," since their size is the result of exaggerated flattening (leptocyte) and thus the presence of the central pallor. The MCV for this type of macrocyte is within normal range. Pseudomacrocytes can be seen in patients with cirrhosis of the liver, obstructive jaundice, post splenectomy and conditions that affect the red cell membrane.
