Keloid
A keloid scar is a thick raised scar. It can occur wherever you have a skin injury but usually forms on earlobes, shoulders, cheeks or the chest. It isn't harmful to your physical health, but it can cause emotional distress. Keloids aren't contagious or cancerous. A keloid is different from a hypertrophic scar. A hypertrophic scar stays within the bounds of the original wound and can fade over time without treatment. Keloids located on a joint might develop hard, tight tissue that restricts movement. Prevention or early treatment is key. A keloid scar may form within months to years of the inciting injury. The signs and symptoms might include:
• Thick, irregular scarring, typically on the earlobes, shoulders, cheeks or middle chest
• Shiny, hairless, lumpy, raised skin
• Varied size, depending on the size of the original injury and when the keloid stops growing
• Varied texture, from soft to firm and rubbery
• Reddish, brown or purplish, depending on your skin color
• Itch
• Discomfort
Early treatment can help minimize growth of a keloid.
Risk Factors:
• Having brown or Black skin
• Having a personal or family history of keloids
• Being under 30
Cause:
It usually occurs due to dysfunction of the wound-healing process. Collagen — a protein found throughout the body — is useful to wound healing, but when the body produces too much, keloids can form.
Keloid growth might be triggered by any sort of skin injury — an insect bite, acne, an injection, body piercing, burns, hair removal, and even minor scratches and bumps.
Sometimes keloids form for no obvious reason.
Prevention:
• Practice good wound care
• Protect your skin from injury
