A keloid is an areas of scaring which is firm, raised, and rubbery and larger than the original wound.[2] The color may be the same as the skin, red, or darker.[2] There may also be itching, burning, or pain.[2] They may not form until months after the initial injury.[4] These lesions are non cancerous.[2]
They occur due to a combination of genetic and environmental factors.[2] In those who are at risk, they can occur after any degree of injury to the skin.[2] The underlying mechanism involves abnormal wound healing.[2] Diagnosis is generally based on examination, though may be confirmed by biopsy.[2] It differs from a hypertrophic scar in that it grows beyond the site of the original wound.[2]
Treatment is difficult.[2] Efforts may include corticosteroids, cryotherapy, surgical excision, radiation therapy, and laser therapy.[2][3] Rates are 4.5 to 16% in people with darker skin.[2] People between the ages of 10 to 30 are more commonly affected.[4]
