Fat necrosis is necrosis affecting fat tissue (adipose tissue). [1] The term is well-established in medical terminology despite not denoting a specific pattern of necrosis. [ 2 ] Fat necrosis may result from various injuries to adipose tissue, including: physical trauma, enzymatic digestion of adipocytes by lipases , [ 3 ] radiation therapy ...
Pancreatic panniculitis (also known as enzymatic panniculitis, Pancreatic fat necrosis, [10] and subcutaneous fat necrosis) is a panniculitis most commonly associated with pancreatic carcinoma, and more rarely with anatomic pancreatic abnormalities, pseudocysts, or drug-induced pancreatitis.

Fat embolism syndrome occurs when fat enters the blood stream (fat embolism) and results in symptoms. [1] Symptoms generally begin within a day. [1] This may include a petechial rash, decreased level of consciousness, and shortness of breath. [1] Other symptoms may include fever and decreased urine output. [2] The risk of death is about 10%.

Caseous necrosis in T.B. is most common site of dystrophic calcification. Liquefactive necrosis in chronic abscesses may get calcified. Fat necrosis following acute pancreatitis or traumatic fat necrosis in breasts results in deposition of calcium soaps. Infarcts may undergo D.C. Thrombi, especially in veins, may produce phleboliths.
The theory behind this is that fat accumulation within the omentum occludes blood supply to the distal parts of the omentum in addition to making it more susceptible to torsion. Other risk factors for omental infarction are polycythemia, hypercoagulability, and vasculitides plus other conditions which predispose to torsion such as trauma ...
Mobile encapsulated fat necrosis (MEFN) is a rare medical condition featuring the formation of a fibrotic capsule around a small, necrotic mass of fatty tissue. It is asymptomatic and benign but may be mistaken for other neoplasms due to its typical presentation as a firm nodule beneath the skin that can be moved around within the tissue.
Overall treatment depends on preventing kidney failure (renal failure) which is done by rehydrating the patient. It also depends on making urine have a more basic pH (alkalinization of urine). [11] Crush syndrome progression (MC most common,# fracture, MODS multiple organ dysfunction syndrome, RTN renal tubular necrosis).
Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis. In advanced lipodermatosclerosis the proximal leg swells from chronic venous obstruction and the lower leg shrinks from chronic ulceration and fat necrosis resulting in the inverted coke bottle appearance of the lower leg.
