Overview

Green neutrophilic inclusions, commonly known as death crystals or crystals of death, are amorphous blue-green cytoplasmic inclusions observed in neutrophils and monocytes. When stained with Wright-Giemsa stain, they seem vividly coloured and refractile. These inclusions are more common in critically sick individuals, especially those with liver illness, and their presence on a peripheral blood smear is linked to a high likelihood of short-term mortality.

Different intracellular non-living organisms (ergastic compounds) that are not bound by membranes are referred to as inclusions. Stored nutrients/deutoplasmic substances, secretory products, and pigment granules are all included. Glycogen granules in the liver and muscle cells, lipid droplets in fat cells, pigment granules in some skin and hair cells, and crystals of various types are examples of inclusions. Cytoplasmic inclusions are a type of biomolecular condensate formed by the separation of liquid-solid, liquid-gel, or liquid-liquid phases.

O. F. Müller was the first to notice these structures in 1786. Cytoplasmic molecular aggregates like as pigments, organic polymers, and crystals are examples of inclusions. Cell inclusions include fat droplets and glycogen granules, for example, Death Crystals are crystals found on Forbodulon Prime that allow those who possess them to predict their own death in a variety of future circumstances.

Green neutrophilic inclusions, commonly known as death crystals or crystals of death, are amorphous blue-green cytoplasmic inclusions observed in neutrophils and monocytes. When stained with Wright-Giemsa stain, they seem vividly coloured and refractile. Unlike hazardous granulation, the granules may appear in clusters rather than dispersed throughout the cytoplasm. The presence of these inclusions in the bone marrow is more common than in the peripheral blood. Gargoylism and dwarfism are two physical traits connected with this illness.

Clinical significance

Critical green inclusions are uncommon, and when they do appear, they indicate a dismal prognosis, hence the moniker “death crystals.” According to a 2018 study, 56 percent of individuals died soon after the inclusions were discovered (usually within two weeks). Critical green inclusions, on the other hand, are of limited service in forecasting mortality since they are typically identified in critically ill patients whose bad prognosis has already been established for other reasons by the time the crystals are discovered.

Due to the high occurrence of critical green inclusions found in patients of acute hypoxia and ischemic hepatitis, the inclusions were long thought to represent bile products phagocytized after fulminant hepatic damage. Recent research has revealed that the inclusions stain positive for Oil Red O rather than bile stains, indicating significant lipid content. Furthermore, several patients with severe green inclusions were not linked to significant liver damage. It is now thought that crucial green inclusions are more likely to be phagocytized lysosome breakdown products associated with tissue damage.

Composition

The composition of the inclusions is not well understood, but transmission electron microscopy has shown that they are rich in lipids and possibly related to lipofuscin. Microscopic examination of liver tissue in patients with critical green inclusions has demonstrated prominent deposition of lipofuscin, suggesting that the white blood cell inclusions represent phagocytosis of this substance following severe injury to the liver.
