Dohle bodies are seen in:
**Core Concept**
Dohle bodies are azurophilic inclusions found in the cytoplasm of neutrophils, typically seen in conditions of acute inflammation, infection, or tissue damage. They are composed of rough endoplasmic reticulum and ribosomes, indicating active protein synthesis in response to stress.
**Why the Correct Answer is Right**
Dohle bodies are characteristic of conditions such as acute bacterial infections, severe burns, or trauma, where there is a massive release of inflammatory mediators and subsequent activation of neutrophils. This leads to the formation of Dohle bodies as part of the neutrophil's response to the stress. The presence of Dohle bodies is often indicative of a severe underlying condition.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect, as Dohle bodies are not typically seen in viral infections, which usually induce a different type of inflammatory response.
**Option B:** Incorrect, as while Dohle bodies can be seen in some cases of leukemia, they are not specific to this condition and are more commonly associated with acute infections.
**Option C:** Incorrect, as Dohle bodies are not a feature of autoimmune disorders, which often involve a different type of immune response.
**Clinical Pearl / High-Yield Fact**
Dohle bodies are a classic example of a cytoplasmic inclusion seen in neutrophils, and their presence should prompt the examiner to consider a diagnosis of acute infection or tissue damage.
**Correct Answer:** C. Leukemia
