RBC Inclusion Bodies

  • Basophilic Stippling
    • Dark blue to purple granules evenly distributed in the RBC.
    • Also known as Punctate Basophilia.
  • Siderotic Granules
    • Multiple dark blue irregular granules.
    • Stain with Prussian blue iron staining.
    • Pale blue clusters are visible with Wright staining.
    • Also known as Pappenheimer Bodies.
  • Howell-Jolly Bodies
    • Usually appear singly in a cell (only one per cell).
    • Often round.
