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.

Conditions with RBCs

Sickle cell disease

Anemia

Myospherulosis

General

  • Granulomatous reaction to fat and RBCs.[2][3]
  • Rare.[4]

Etiology:

Microscopic

Features:

  • Phagocytosed RBCs.
    • Round aggregates of red blood cells ~10-20 RBCs in diameter (80-160 micrometers).
