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.
What is a keloid ?
A keloid is a firm to hard, irregularly shaped, thickened overgrowth with claw like projections. It may be asymptomatic or painful, tender and pruritic (itchy).
Is there a known cause ? It occurs only in people who are predisposed to it, i.e. have a tendency to form keloids.
Triggering factors are: Trauma which may be due to a needle prick, vaccination, cut with a knife, insect bite etc. Infections like furuncle, abscess, cystic acne etc. Burns and scalds.
