Final answer:
Döhle bodies are blue-gray oval RNA inclusions near the periphery of neutrophils, suggesting various conditions. Neutrophils are granulocytes with a multi-lobed nucleus and fine lilac-staining granules for pathogen neutralization.
Step-by-step explanation:
The blue-gray oval inclusions composed of RNA near the periphery of neutrophils are known as Döhle bodies. These are indicative of various conditions such as infections, burns, trauma, or may be seen in myelodysplastic syndromes. Neutrophils are the most common type of granulocyte and leukocyte found in the peripheral blood. A neutrophil is characterized by its multi-lobed nucleus and the fine granules within its cytoplasm which stain light lilac and are indicative of its ability to neutralize pathogens. These granules contain enzymes that are vital to the cell's phagocytic function in fighting infections.
