انسانی جسم ذخم میں مرمت کرنے اور زخم کی حفاظت کرنے کے لئے ٹھوس ٹشو کی شکل میں ایک پرت بناتاہے. بعض اوقات یہ ٹشو ضرورت سے زیادہ تیارہونے لگتا ہے،اور جسم کی سطح پر ہموار اور سخت شکل اختیار کر جاتا ہے. یہ اصل زخم سےبڑا ہوتا ہے. سینے، کندھے، اور گالوں کی جلد اس مرض سے زیادہ متاثر ہوتی ہے. تاہم، کیلوائڈس سے جسم کا کوئی بھی حصہ متاثر ہوسکتا ہے. اگرچہ کیلوائڈس صحت کے لیے نقصان دہ نہیں ہیں،لیکن ان کی وجہ سے کاسمیٹک مسائل پیدا کرسکتے ہیں. اس بیماری کی وجہ سے بننے والے کھرنڈ جامنی رنگت کے حامل ہوتے ہیں اور وقت کے ساتھ ان کاحجم بڑھتا چلا جاتا ہے۔ یہ عام ذخموں کے کھرنڈ کی طرح مندمل نہیں ہوتے۔ ان کا علاج کافی دقت طلد ہو سکتا ہے۔ زیادہ تر اس کے نتائج بھی تسلی بخش نہیں ہوتے۔ یہ درمیانی عمر کے افراد میں زیادہ عام ہے۔ یہ موروثی طور پر منتقل ہونے والی بیماریوں میں سے ہے۔
Keloids are basically scars that keep on growing even after most of the necessary scarring is completed. A keloid scar, or simply keloid, is a very protrusive or bulging scar that grows very abnormally compared to the surrounding skin. Additionally, its appearance is characterized by purplish color and a smooth, even top. They are abnormally shaped and keep on getting bigger with time; they do not fade away like normal scars.
Keloids basically originate when scar tissues overgrow. The resulting scars are generally bigger than the wound on which it forms. It takes them some time to grow to their largest extent; some weeks and even months.
Keloid symptoms generally include:
Even though keloid scars could be itchy, they are not a major health concern. One might feel discomfort or sensitive when the clothing rubs against these scars.
Skin injuries are one primary cause associated with keloids. These injuries include acneand chickenpoxscars, sites where there are surgical incisions and vaccine injection. Ear piercings and burns can also cause keloid scarring. In fact, keloid scarring tends to happen in places where injury has happened.
About 1 in 10 people have had keloid scars. It does not matter if the individual is a male or female; it appears equally in both genders. Scientists have observed that people having darker skins reported more cases of keloids. There is also a genetic link tied to this condition. The predisposition to have keloids could be transferred from the parents to the children.
One specific gene that is understood to cause keloid scarring is the AHNAK gene. Researchers have studied this gene and come up with an observation that those who have this gene are much more likely to have keloids than those who are without it.
The factors that put the individual at the highest risk for developing keloids include genetics. This condition seems to be associated to familial links as it has been observed that if the parents have keloid-ic growths, their offspring will probably also have it. Along with AHNAK gene, a mutation in the NEDD4 gene could also predispose the person to have keloid scarring in the future.
Other than genes, different skin colors and different ethnicities could also determine how much vulnerable one is to this scarring. Basically, those who have a darker skin are about 15 times more likely to have it. This means that this condition is more common in those who have a South Asian, Hispanic or African descent.
Furthermore, the age at which keloids usually occurs is the middle age; meaning that it occurs less frequently in children and the older people.
Keloid scars are seldom treated without difficulty. In fact, sometimes the treatment might not even have the desired effect. This is why it is essential to not let the skin injury even happen. If the skin is still injured, one should use pads like pressure or silicone gel pads to avoid keloid scarring.
If the keloid scarring has already taken place one could make sure that it at least looks less cosmetically unpleasant. So, one should avoid exposing skin to the sun for too long as too much exposure would result in the keloid scar standing out more compared to the surrounding skin. One way to avoid sun exposure is by covering the keloid in regular clothes. If that is not possible, the person should at least apply sunscreen.
