Coagulative Necrosis, Liquefactive Necrosis, Fibrinoid Necrosis, Fat Necrosis, & Caseous Necrosis
Coagulative Necrosis: This type of cell death typically occurs in organs like the heart and kidneys due to ischemia or lack of blood flow. The architecture of dead tissues is preserved for a few days, giving the affected tissue a firm texture. Cells appear as ghost-like structures due to denaturation of enzymatic and structural proteins, preventing proteolysis of the dead cells. 🫀💔 #CoagulativeNecrosis #HeartHealth #KidneyAwareness
Liquefactive Necrosis: Commonly found in the brain, liquefactive necrosis results from ischemic injury to neurons and glial cells. It's characterized by the transformation of the tissue into a liquid viscous mass, as hydrolytic enzymes digest the cells. Infections causing abscesses can also lead to this type of necrosis due to the action of immune cells. 🧠💧 #LiquefactiveNecrosis #BrainHealth #InfectionControl
Fibrinoid Necrosis: This occurs primarily in blood vessels and is associated with immune reactions involving blood vessels, such as vasculitis or hypertension. It is characterized by the deposition of complexes of antigens and antibodies, combined with fibrin that leaks out of vessels, leading to a bright pink appearance under the microscope. 🩸🔬 #FibrinoidNecrosis #VasculitisAwareness #Hypertension
Fat Necrosis: Typically occurs in adipose tissue due to trauma or pancreatitis. Enzymes, particularly lipases, break down triglycerides, releasing free fatty acids that combine with calcium to form soaps (saponification), leading to opaque and chalky appearance. It’s often seen in the breast, pancreas, and abdominal structures. 🍳🛁 #FatNecrosis #Pancreatitis #BreastHealth
Caseous Necrosis: A distinctive form of cell death usually associated with tuberculosis infections, where the affected tissue has a cheese-like appearance. The necrotic area is enclosed within a distinctive inflammatory border, known as a granuloma. Under the microscope, the tissue structure is completely lost and replaced by amorphous granular debris. 🧀🦠 #CaseousNecrosis #Tuberculosis #InfectiousDiseases
