A keloid is a firm, itchy, irregularly shaped overgrowth of scar tissue that forms on the surface of a wound. Keloids are the result of overproduction of the skin protein collagen during the healing process.
They are more common in dark-skinned people, and susceptibility to them may run in families. They usually develop after skin damage—even minor damage from, say, a small cut may cause a keloid—but they can also sometimes occur without any apparent cause.
Keloids are harmless and do not require treatment.
Possible treatments include corticosteroids, silicone preparations, pressure dressings, freezing, or certain chemotherapy or wart medications. However, treatment is not always successful
