scar,

fibrous connective tissueconnective tissue,
supportive tissue widely distributed in the body, characterized by large amounts of intercellular substance and relatively few cells. The intercellular material, or matrix, is produced by the cells and gives the tissue its particular character.

 that forms at the site of injury or disease in any tissue of the body. Scar tissue may replace injured skin and underlying muscle, damaged heart muscle, or diseased areas of internal organs such as the liver. Dense and thick, it is usually paler than the surrounding tissue because it is poorly supplied with blood, and although it structurally replaces destroyed tissue, it cannot perform the functions of the missing tissue. Scar tissue may therefore limit the range of muscle movement or prevent proper circulation of fluids when affecting the lymphatic or circulatory system. Extensively scarred tissue may lose its ability to function normally.

Scar

 

the end result of the development of connective tissue at the site of the healing of a wound or ulcer. The timely surgical treatment of an incised wound with smooth margins leaves a soft and sometimes barely noticeable linear scar. Large wounds that suppurate and heal by second intention form granulations and subsequently epithelize, resulting in the formation of broad scars that are attached to underlying tissues.

Excessive scar tissue that is elevated above the skin surface is called a keloid. Extensive scars formed after burns or the prolonged healing of suppurative wounds in the area of extremity joints or on the neck result in a limitation of mobility, or contracture; these scars require plastic surgery. Scars that develop after the healing of gastric or duodenal ulcers often lead to the deformation of the stomach and duodenum, the disruption of evacuation from the stomach, and the development of pyloric stenosis.
