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 ...
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 ...
Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue. [1] [2]
Scar tissue is composed of the same protein as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in fibrosis the collagen cross-links and forms a pronounced alignment in a single direction. [1]
This occurs as a reaction to tissue damage, [1] including as a consequence of medical device implantation. Dystrophic calcification can occur even if the amount of calcium in the blood is not elevated, in contrast to metastatic calcification , which is a consequence of a systemic mineral imbalance, including hypercalcemia and/or ...
Fat necrosis is a condition in which the normal fat cells of the breast become round lumps. Symptoms can include pain, firmness, redness, and/or bruising. Fat necrosis usually goes away without treatment but can form permanent scar tissue that may show up as an abnormality on a mammogram. [8]
Coagulative necrosis occurs in the heart or kidneys, leaving behind a "ghost" framework of the affected cells. In specific tissues, like the liver, necrotic areas may regenerate if the surrounding cells are viable. However, non-functional scar tissue and collagen replace necrotic tissue in organs like the heart or brain. Additionally ...
In medicine, desmoplasia is the growth of fibrous connective tissue. [1] It is also called a desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, [1] or scar tissue within the abdomen after abdominal surgery. [1]
