Summary

Summary of Cytoplasmic Variations
Name ImageDescription
Döhle Bodies
Small, light blue-gray, irregular-staining patches of cytoplasm are seen near the edge of the cell.
Associated with:
  • infections
  • burns
  • leukemia
  • chemotherapy
  • inflammatory states
Toxic Granules
Large granules in the cytoplasm of segmented and band neutrophils in the peripheral blood. It can be dark, purplish blue, or almost red.
Associated with:
  • infections
  • Rheumatoid Arthritis (denatured proteins)
  • autophagocytosis
Vacuoles
They appear as clear, unstained circular areas in the cytoplasm.
Associated with:
  • bacterial infections
  • septicemia
  • aging cells
Auer Rods
Red-staining, needle-like bodies can be seen in the cytoplasm of myeloblasts and promyelocytes.
Associated with:
  • Myeloproliferative neoplasms such as CML
  • Acute myeloblastic leukemias such as AML and APL
Chédiak-Higashi
Cellular abnormality involving the fusion of cytoplasmic granules. These large abnormal granules can be seen in the cytoplasm of neutrophils, eosinophils, basophils, monocytes, and lymphocytes.
Associated with:
  • Chédiak-Higashi syndrome (anomaly)
May-Hegglin
Pale blue inclusions in neutrophils are sometimes referred to as Döhle-like bodies accompanied by giant platelets.
Associated with:
  • May-Hegglin anomaly
Alder-Reilly
Larger than normal purple-staining inclusions are seen in all mature white blood cells.
Associated with:
  • Alder-Reilly anomaly
