A keloid is an extra growth of scar tissue over a skin wound. It grows beyond the margins of the skin wound. A keloid can vary in size from one to several inches. They are not harmful to general health.

Keloids can occur anywhere but they are more common on:

  • Earlobes
  • Shoulders
  • Upper back
  • Chest
  • Back of scalp and neck

Scar tissue is a part of the normal healing process. With keloids, the scar tissue grows in an uncontrolled manner. The scar continues to grow even after the wound has been covered. The growth can continue for weeks or months.
