The red blood cell, abbreviated RBC, is the carrier of oxygen to tissue. It is seen daily by pathologists.
It is approximately 8 micrometers in diameter.[1]
Precursors
Reticulocyte
The direct precursor to the RBC is the reticulocyte.
Image:
Normoblast
Normoblasts are the nucleated precursors of RBCs.

Myospherulosis
General
Etiology:
- Exposure to dying fat, e.g. fat necrosis of the breast.
- Malignancy, e.g. renal cell carcinoma.[4]
Microscopic
Features:
- Round aggregates of red blood cells ~10-20 RBCs in diameter (80-160 micrometers).
