Red blood cells constitute the primary cellular component in blood. Red blood cells that are mature are biconcave discs which have no nucleus and are devoid of most cell organelles , including the lysomes, endoplasmic-reticulum and mitochondria.
However, a variety of abnormal erythrocyte morphology can be seen in a variety of medical conditions:
- Anisocytosis: Variation of size
- Poikilocytosis: Variation of shape
- Color variation
- The presence of inclusion bodies
Anisocytosis: Variation in size
The variation in dimensions of RBC is known as anisocytosis.
The typical dimension of RBC is 7.5+/-0.2 micrometers in diameter. Small lymphocyte nucleus can be an excellent indicator of how big is RBC. Anisocytosis can be classified into Macrocytosis and Microcytosis.
- Microcytosis: RBCs less than normal are thought to be microcytes.
The signs of microcytosis are found in iron deficiency anemia, lead poisoning, thalassemia, sideroblastic anemia, and anemia of chronic disorders.
- Macrocytosis: RBCs that are larger than normal in size are thought to
