Keloid
Book AppointmentKeloids form due to the overgrowth of scar tissues. When the skin is wounded, scar tissues form to cover the wound for protection. Occasionally, these scar tissues grow excessively to form keloids which are smooth, hard formations, slightly elevated and reddish purple in colour.
Keloids can be much larger than the wound, irregular in shape, and tend to enlarge progressively. They don’t fade away like scars. They can appear anywhere on the skin that suffers a wound, but are usually found on the chest, shoulders, earlobes, and cheeks.
Doctors are unaware of the exact cause of keloids but it may be caused by lack of communication by the cellular signals that control growth and proliferation. It is also understood to be hereditary. Keloids affect both genders, but are less common in elderly and children. People of Asian and African origin are thought to be more susceptible to keloids.
When to seek expert advise
You may feel the need to visit a doctor for keloid if it causes irritation due to friction with clothing, continues to grow, or is a cosmetics concern or when it causes recurrent infections. Visit a doctor at the Teeth and Skin Service Line at The Aga Khan University Hospital if you feel the need to get it treated.
