Overview of Keloid

Keloid or keloid disorder is the overgrowth of scar tissues on the injured area. Normally, these scar tissues are formed to protect the wound. But If these scar tissues overgrow, it results in hard keloid (انگور نشان زدہ نسیج کا زیادہ بڑھاؤ) formation. They’re usually formed on the chest, shoulders, earlobes, and cheeks. But keloids can develop on any part of the body. Although keloids don’t cause any harmful effects but can create cosmetic and appearance concerns.

Occurrence of Keloids

Keloids are developed only in humans and occur in 5-15% of wounds. As per studies, about 10% of people experience keloid. It occurs equally in both sexes (men and women). Black people are more prone to keloids as compared to others. 


Signs and Symptoms of Keloid

Some common symptoms of a keloid include:

  • A localized area that is flesh-colored, pink, or red
  • An itchy patch of skin
  • A lumpy or ridged area of skin that’s usually raised
  • An area that continues to grow larger with scar tissue over time
  • Discomfort, tenderness, or possible irritation from clothing or other forms of friction.


Types of Keloid

Causes of Keloid

Keloid scarring can be due to different types of skin injuries such as:

  • Acne scars
  • Burns
  • Scratches
  • Chickenpox scars
  • Vaccination sites
  • Ear piercing
  • Surgical incision sites

Risk Factors of Keloid

Some risk factors related to keloid formation include:

  • Pregnant
  • Asian descent
  • Younger than 30 years of age
  • Latino descent
  • Genetics


As per genetic studies, the AHNAK gene may be involved in keloid formation. People having this gene are more likely to develop keloid scars as compared to those who don’t have these scars.




You can prevent keloid by following ways:

  • After ear piercing, take good care of it to prevent keloid formation. If you notice thickening at your earlobe, immediately remove the earring and use pressure earrings.
  • To prevent keloid after surgery, tell your surgeon before about past keloid. After knowing this, the surgeon may reduce the chances of keloid formation after surgery.
  • You can avoid skin thickening from turning into a keloid by wearing pressure garments. A dermatologist may help you with a pressure garment.
  • Before tattoo, body piercing, or other cosmetic surgery try a test spot. It will tell you about your skin’s ability to heal. If the test area starts to be thickened you can stop it to prevent keloid formation.


Take good care of your wound by following the wound-care tips.

  • Location of Scar
