User:Mr. Ibrahem/Keloid

A keloid is an area of scaring which is firm, raised, and rubbery and larger than the original wound. The color may be the same as the skin, red, or darker. There may also be itching, burning, or pain. They may not form until months after the initial injury. These lesions are non cancerous.

They occur due to a combination of genetic and environmental factors. In those who are at risk, they can occur after any degree of injury to the skin. The underlying mechanism involves abnormal wound healing. Diagnosis is generally based on examination, though may be confirmed by biopsy. It differs from a hypertrophic scar in that it grows beyond the site of the original wound.

Treatment is difficult. Efforts may include corticosteroids, cryotherapy, surgical excision, radiation therapy, and laser therapy. Rates are 4.5 to 16% in people with darker skin. People between the ages of 10 to 30 are more commonly affected.
