Fibrosis

A subsurface collagenous soft tissue replacement that occurs as a result of chronic inflammation. The tissue appears and feels thick and dense. Fibrosis may occur as a result of chronic inflammation around dental implants that support prosthetic crowns. The tissue becomes thick and enlarges with collagen deposition in the surrounding gingival tissue. There is usually no bleeding on probing of the surrounding sulcus. The collagenous deposition may occur interproximally at supporting implants that fill the embrasure space to mimic interdental papillae.

The formation of fibrous tissue as a reparative or reactive process.

Any pathological condition where fibrous connective tissue invades any organ, usually as a consequence of inflammation or other injury.

An abnormal formation of fibrous tissue as a reparative or reactive process, as opposed to the formation of fibrous tissue that is a normal constituent of an organ or tissue.

Morbid increase of fibrous tissue in the body; fibroid degeneration of blood capillaries.

The abnormal formation of fibrous tissue.

The formation of fibrous tissue or scar is usually a reparative or reactive process.

The process of replacing damaged tissue by scar tissue.

Increase in the formation of fibrous connective tissue, either normally as in scar formation, or abnormally to replace normal tissues, especially in the lungs, uterus, or heart.

Increase or abnormal growth of fibrous or connective tissue in reparative or reactive processes.

An abnormal increase in the amount of fibrous connective tissue in an organ, body part, or tissue. Fibrosis occurs normally in the formation of scar tissue or as a reaction to foreign bodies in the tissue. Cystic fibrosis is a life-threatening inherited disorder that causes severe lung damage and nutritional deficiencies.

Thickening and scarring of connective tissue, most often a consequence of inflammation or injury. Pulmonary interstitial fibrosis is thickening and stiffening of the lining of the air sacs (alveoli) of the lungs, causing progressive breathlessness.

The formation of fibrous or scar tissue, usually due to infection, injury or surgical operation.

The repair and replacement of inflamed tissues or organs by connective tissues. The process results in the replacement of normal cells by fibroblasts (and eventually, the replacement of normal organ tissue by scar tissue).

The process of developing fibrous or scar tissue that can occur subsequent to inflammation and the destruction of normal tissue.

Fibrosis is the excessive growth of scar tissue or connective tissue. It can develop as an exaggerated healing response to infection, inflammation, or injury. Additionally, fibrosis may occur when a tissue lacks oxygen, often due to inadequate blood flow (for instance, in heart muscle damaged by a myocardial infarction).

Fibrosis is a condition where specialized structures, such as kidney or muscle cells, are replaced by fibrous tissue, leading to impaired organ function. An excessive growth of fibrous tissue can compress hollow structures, as seen in retroperitoneal fibrosis, where the ureters (tubes draining urine from the kidneys to the bladder) become blocked. When fibrous tissue forms within a muscle after a tear, it causes the muscle to shorten and disrupts its normal contraction. Regular stretching and exercise of the muscle are essential to reduce the likelihood of further tears from occurring.
