A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings , cuts and burns.
[1] [2] Fibrosis is the formation of excess tissue in replacement of necrotic or extensively damaged tissue. Fibrosis in the heart is often hard to detect because fibromas, scar tissue or small tumors formed in one cell line, are often formed. [3] Because they are so small, they can be hard to detect by methods such as magnetic resonance ...
The word infarction means that some area of tissue has died due to a lack of blood flow, and therefore a lack of oxygen. “Myo” refers to the muscle, and “cardial” refers to the heart tissue. So with a heart attack, or MI, you have death of heart muscle cells because of a lack in blood flow, a process called necrosis.
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]
In scars, rete pegs are lost; [23] through a lack of rete pegs, scars tend to shear easier than normal tissue. [23] The endometrium, the inner lining of the uterus, is the only adult tissue to undergo rapid cyclic shedding and regeneration without scarring, shedding and restoring roughly inside a 7-day window on a monthly basis. [24] All other ...
Arthrofibrosis can occur after total knee replacement or partial knee replacement, when excessive scar tissue (collagen fibril) deposition occurs in and around the knee. This can be accompanied by shortening of the patellar tendon (patella baja/infera) which can also contribute to limited flexion.
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 ...
Keloids form within scar tissue. Collagen, used in wound repair, tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red. [6] Although they usually occur at the site of an injury, keloids can also arise spontaneously.
