WebIf there are many neutrophils in the bloodstream containing Döhle bodies, these can be referred to as toxic neutrophils. Toxic neutrophils can also correspond to neutrophils that possess a more basophilic cytoplasm, basophilic granulation (infrequently observed), or cytoplasmic vacuoles in addition to one of the preceding cytoplasmic changes. WebImmature neutrophils tend to show features of toxicity (cytoplasmic basophilia, Dohle bodies, cytoplasmic vacuolation), have more clumped chromatin than monocytes and when they are metamyelocyte or myelocyte forms, the nucleus is eccentric. Cytoplasmic borders, when they abut adjacent red blood cells tend to have a light rim.
