Area of fibrous tissue resulting from the biologic process of wound repair that replaces normal tissues destroyed by injury or disease. Called also a cicatrix.

Mark left on stem by a fallen leaf, or on seed by separating from fruit.

A mark left on the skin or other tissue after a wound, burn, ulcer, lesion, or other injury has healed. The degree of scarring depends on the nature of the injury, as well as a person’s age, heredity, and skin type. Scars tend to shrink and become less noticeable as they age. However, some individuals undergo surgery to improve the appearance of scars. A keloid is a raised, firm irregularly shaped scar caused by abnormal healing; it has a tendency to return.

A healed wound, ulcer or breach of tissue. A scar consists essentially of fibrous tissue, covered by an imperfect formation of epidermis in the case of scars on the surface of the skin. The fibrous tissue is produced by the connective tissue that migrates to the wound in the course of its repair. Gradually this fibrous tissue contracts, becomes more dense, and loses its blood vessels, leaving a hard white scar.

A mark left in the skin or an internal organ by the healing of a wound, sore, or injury because of replacement by connective tissue of the injured tissue. Scars may result from wounds that have healed, lesions of diseases, or surgical operations. When it first develops a scar is red or purple. It later takes on the skin color of the patient.

A lightly raised mark on the skin formed after an injury or lesion of the skin has healed.

A scar is the residual mark that remains after damaged tissue has healed. Scar tissue develops not only on the skin’s surface but also internally, such as at the location of a muscle tear or following surgical procedures.

The body initiates the healing of wounds or lesions by boosting the production of a resilient, fibrous protein called collagen at the site of the injury. This aids in the creation of new connective tissue around the affected area. When the edges of a lesion are aligned during the healing process, a slender and light-colored scar develops. Conversely, if the edges remain apart, more substantial scarring is likely to result.

A hypertrophic scar is a notable and unattractive scar that can emerge at the location of an infected wound. Certain individuals may have a genetic predisposition to develop these kinds of scars.

A keloid is a sizeable and unevenly shaped scar that persistently expands due to ongoing production of excess collagen even after the wound has healed. This particular type of scar is more prevalent among individuals of black ethnicity compared to those of white ethnicity.

Adhesions are regions of scar tissue that develop between disconnected segments of internal organs. They represent a possible complication following intestinal surgery.

The mark left behind after a wound or disease has healed in a tissue, particularly the skin. Also known as cicatrix.
