Keloid

Keloids are raised, reddish nodules that develop at the site of an injury A keloid is a greatly enlarged scar that projects above the skin surface. The skin heals by formation of scar tissue, which at first is often red and somewhat prominent. As the months pass, a scar usually becomes flat. Keloid is a scar which is usually just a cosmetic problem. They never become malignant. A keloid is a raised growth of fibrous scar tissue that forms over an area of trauma to the skin. It extends beyond the area of the original injury. A keloid is abnormal because the scar extends above and beyond the site of the original injury. Normal scars stay confined to the site of injury. Keloids are thick, smooth areas of pink scar tissue. The scar tissue is raised above the level of the surrounding skin. African Americans are more likely to develop keloids on the legs or feet than either Asians.

Keloid Causes

The cause of keloids is unknown. But most of the researchers believe that keloids are caused by due to the body's failure to turn off the healing process needed to repair skin. Exposure to the sun during the first year of the keloid's formation will cause the keloid to tan darker than surrounding skin.

• We don't know why keloids form.
• While most people never form keloids, others develop them after minor injuries and even insect bites or pimples.
• Keloids may form on any part of the body, although the upper chest and upper back are especially prone to keloid formation.
• Keloids occur from such skin injuries as surgical incisions, traumatic wounds, vaccination sites, burns, chickenpox , acne , or even minor scratches. They are fairly common in young women and African Americans. Keloidosis is a term used when multiple or repeated keloids are produced.
• Keloids are a cosmetic nuisance and never become malignant.
• Keloids occur more frequently in dark-skinned people.
• Exposure to the sun during the first year of the keloid's formation will cause the keloid to tan darker than surrounding skin.

Keloid Symptoms

Keloids look like exaggerated scars. They are shiny and hairless; usually they feel hard and rubbery; and new ones are often red or purple, becoming browner and sometimes paler as they age. Most people with keloids have only one or two. However some people have many, especially if they have come up after acne or chickenpox scars.

1. Keloids are usually raised and look shiny and dome-shaped.
2. The color of keloids may vary from pink to red.
3. They may be located over the site of a wound, injury, or other lesion. Keloids may form on any part of the body, although the upper chest, shoulders and upper back are especially prone to keloid formation.
4. Some keloids become quite large and unsightly.
5. Keloids are less common in children and the elderly.
6. Although people with darker skin are more likely to develop them, keloids can occur in men and women of all skin types.

Keloids are most commonly located on the chest, upper back, and shoulders. However, they can appear almost anywhere, such as in surgical scars any place o the body and in the earlobes or other areas that have been pierced for cosmetic purposes.

KeloidTreatment

It is difficult to remove keloids completely by allopathic treatment. Surgery is not a good option because the scar formed from surgery may grow into another keloid. Though there is no any dependable allopathic treatment to cure keloids.

The best treatment is to inject a long-acting cortisone into the keloid once a month. After several injections with cortisone, the keloid usually becomes less noticeable and flattens in three to six months time. Other treatments have included non-antibiotic moisturizing ointments. However, it should be understood that there is no clear answer for keloid and hypertrophic scar formation. Some individuals simply have the tendency to develop keloids and despite surgical laser, chemotherapy, radiation therapy, or pharmaceutical agents, the keloids can persist.
