keloid
Keloid Background- It is a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to flesh-coloured or red to dark brown in colour. A keloid scar is benign and not contagious, but sometimes accompanied by severe itchiness, pain,[2] and changes in texture. In severe cases, it can affect movement of skin.
Keloid is the medical term for the type of the scar which is characterized by the constant growth and expanding over the nearby tissue. Keloids, are, additionally, protuberant(swollen or buldging), soft and of pink or purple colour. That is, they appear as the consequence of the excessive accumulation of the type 3 collagen.
What causes it-What is the cause of keloids?Doctors do not understand exactly why keloids form in certain people or situations and not in others. Changes in the cellular signals that control growth and proliferation may be related to the process of keloid formation, but these changes have not yet been characterized scientifically.
Which people are most susceptible to keloids?Keloids are equally common in women and men, although at least in times past more women developed them because of a greater degree of earlobe and body piercing among women. Keloids are less common in children and the elderly. Although people with darker skin are more likely to develop them, keloids can occur in people of all skin types. In some cases, the tendency to form keloids seems to run in families.
In which area of the body are keloids most likely to appear?Keloids develop most often on the chest, back, shoulders, and earlobes. They rarely develop on the face (with the exception of the jawline).
What are the symptoms of a keloid?Usually there are none; but some are tender, painful, itchy, or cause a burning sensation. The main problem is that their appearance may cause embarrassment.
