Fat necrosis is specialized necrosis of fat tissue, [10] resulting from the action of activated lipases on fatty tissues such as the pancreas. In the pancreas it leads to acute pancreatitis , a condition where the pancreatic enzymes leak out into the peritoneal cavity, and liquefy the membrane by splitting the triglyceride esters into fatty ...
The macroscopic appearance of an area of coagulative necrosis is a pale segment of tissue contrasting against surrounding well vascularized tissue and is dry on cut surface. The tissue may later turn red due to inflammatory response. The surrounding surviving cells can aid in regeneration of the affected tissue unless they are stable or permanent.
Liquefactive necrosis (or colliquative necrosis) is a type of necrosis which results in a transformation of the tissue into a liquid viscous mass. [1] Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn . [ 2 ]
Septicemic plague; Other names: Septicaemic plague: Septicemic plague resulting in necrosis: Specialty: Infectious diseases : Symptoms: DIC (disseminated intravascular coagulation) which causes : tissue death due to lack of circulation/perfusion to that tissue, bleeding into the skin and other organs, which can cause red and/or black patchy rash and hemoptysis/hermatemesis
The visual result of gaseous tissue-infiltration is notable bloating of the torso and limbs. The increased internal pressure of the continually rising volume of gas further stresses, weakens, and separates the tissues constraining the gas. In the course of putrefaction, the skin tissues of the body eventually rupture and release the bacterial gas.
Caseous necrosis or caseous degeneration [1] (/ ˈ k eɪ s i ə s /) [2] is a unique form of cell death in which the tissue maintains a cheese-like appearance. [3] Unlike with coagulative necrosis, tissue structure is destroyed. Caseous necrosis is enclosed within a granuloma. Caseous necrosis is most notably associated with tuberculoma. The ...
Gas gangrene can cause myonecrosis (muscle tissue death), gas production, and sepsis. Progression to toxemia and shock is often very rapid. It can easily be noticed by the large, blackened sores that form, as well as a degree of loud and distinctive crepitus caused by gas escaping the necrotic tissue. [citation needed]
Surgical debridement can be performed in the operating room or bedside, depending on the extent of the necrotic material and a patient's ability to tolerate the procedure. The surgeon will typically debride tissue back to viability, as determined by tissue appearance and the presence of blood flow in healthy tissue. [5]
