A keloid is a special type of scar which results in an overgrowth of tissue at the site of a healed skin injury. Keloids are firm, rubbery lesions or shiny, fibrous nodules and can vary from pink to flesh-colored or red to dark brown in color. Although they are harmless, benign, noncontagious and usually painless, they can be a cosmetic problem. Keloids should not be confused with Hypertrophic scars, which are raised scars that do not grow beyond the boundaries of the original wound and may reduce over time.

What is keloid?
A keloid is a scar that doesn't know when to stop. When the skin is injured, cells grow back to fill in the gap. Somehow, they "know" when the scar tissue is even with the contour of the skin, at which point they stop multiplying. When the cells keep on reproducing, the result is a what is called a overgrown (hypertrophic) scar or a keloid.





A hypertrophic scar is a thick, raised, smooth area that is confined to the site of injury. It diminishes over a period of one year or more.





A keloid, by contrast, may extend beyond the site of injury. Keloids do not subside
Reply:How are keloids formed ?


Normally when there is a wound on the skin due to trauma or infection, it heals with scarring. If the scar tissue continues to grow beyond the margins of the original wound, it forms a keloid.
