A keloid scar is a type of scar that results in an overgrowth of tissue at the site of healed skin injury due to aggressive healing process. This type of scar grows and extends beyond the site of injury unlike hypertrophic scar. They occur as a result of the body’s continuous production of collagen which is a fibrous protein after the healing of the wound.
They often appear red or pink in color as compared to the surrounding normal skin. They are firm, rubbery lesions; they may appear shiny or as fibrous nodules. Keloid scars may be accompanied by severe itching, pain and may limit mobility if they are extensive. They may vary in size and some types may increase in size. They may occur anywhere on the body although some areas are more susceptible to form keloid scars such as the deltoid region. They occur more often in darker skinned patients.
