INTRODUCTION

• A keloid is an abnormal proliferation of scar tissue that forms at the site of cutaneous injury (surgical incision or trauma); it does not regress and grows beyond the original margins of the scar. • Keloids are benign dermal fibroproliferative tumors with no malignant potential. • The production of extracellular matrix proteins, collagen, elastin, and proteoglycans presumably is due to a prolonged inflammatory process in the wound.
