Critical green inclusion

Uncommon card · No. 101262

Critical green inclusions, also known as green neutrophilic inclusions and informally, death crystals or crystals of death, are amorphous blue-green cytoplasmic inclusions found in neutrophils and occasionally in monocytes. They appear brightly coloured and refractile when stained with Wright-Giemsa stain. These inclusions are most commonly found in critically ill patients, particularly those with acute liver failure. Their presence on the peripheral blood smear is associated with a high short-term mortality rate.
