What causes toxic granulation in neutrophils?
Toxic granulation is seen in cases of severe infection, as a result of denatured proteins in rheumatoid arthritis or, less frequently, as a result of autophagocytosis. Infection is the most frequent cause of toxic granulation. This phenomenon may be seen in cells which also contain Döhle bodies and/or vacuoles.
What does toxic granulation in WBC mean?
Toxic granulation is the term used to describe an increase in staining density and possibly number of granules that occurs regularly with bacterial infection and often with other causes of inflammation (Fig. 5.75). It can also be a feature of administration of granulocyte colony-stimulating factor.
What does neutrophils with vacuoles mean?
The presence of vacuolated polymorphonuclear neutrophils in blood smears of patients suffering from infection appears to be associated with massive bacterial growth and to constitute a very early symptom of rapidly life-threatening septicaemia.
What is toxic granulation in a CBC?
Toxic granulations are darker-coloured granules that can be seen under a microscope in neutrophils, the most abundant class of white blood cells. These granules are often larger and more abundant than normal granules. Their presence is non-specific and usually signals a bacterial infection or inflammation.
What causes toxic Vacuolation?
Toxic vacuolation, also known as toxic vacuolization, is the formation of vacuoles in the cytoplasm of neutrophils in response to severe infections or inflammatory conditions….

What are vacuoles in neutrophils?
Vacuoles are clear, unstained areas in the cytoplasm of neutrophils. They may be a degenerative result of prolonged contact with EDTA anticoagulant. However, when accompanied by toxic granulation and/or Döhle bodies, these vacuoles may be attributed to any of the conditions stated above.
What causes toxic granulation in a neutrophil cell?
Toxic granulation is characterized by the presence of few to many prominent primary blue-black granules in the cytoplasm of neutrophils, and they’re unevenly distributed. This is associated with: Toxic granulation is seen here in a neutrophil in response to either an infection, allergen, or as a side effect of medication, chemotherapy, or burns.
When do you see toxic vacuolation in neutrophils?
Toxic Vacuolation in Neutrophils Toxic vacuolation is a parameter that can be called when performing peripheral blood smears. This finding is classically associated with infections or burns, and is often seen alongside toxic granulation of the neutrophils as well as dohle bodies.
What are the vacuoles of a neutrophil body?
Vacuoles are clear, unstained areas in the cytoplasm of neutrophils. They may be a degenerative result of prolonged contact with EDTA anticoagulant. However, when accompanied by toxic granulation and/or Döhle bodies, these vacuoles may be attributed to any of the conditions stated above. Toxic vacuolization is indicated by the arrows in…
Which is the most common cause of toxic granulation?
Toxic granulation is manifested by the presence of large granules in the cytoplasm of segmented and band neutrophils in the peripheral blood. Infection is the most frequent cause of toxic granulation. This phenomenon may be seen in cells which also contain Döhle bodies and/or vacuoles.
