What characteristic is not found in toxic neutrophils?

• A. Vacuolated cytoplasm
• B. Howell-Jolly bodies
• C. Dohle bodies
• D. Basophilic cytoplasm

Answer: (B)

The important concept is that toxic neutrophils show specific cytoplasmic changes due to an accelerated and stressed maturation process in severe infection or inflammation. In these cells you commonly see cytoplasmic basophilia, vacuolation, and inclusions known as Döhle bodies, which are pale blue aggregates of rough endoplasmic reticulum. Howell-Jolly bodies, on the other hand, are residual DNA fragments found inside red blood cells, not neutrophils. They appear with certain RBC problems (like spleen dysfunction or high RBC turnover) and do not occur as a feature of neutrophil toxic change. So the characteristic not found in toxic neutrophils is the presence of Howell-Jolly bodies.
