Keloid


keloid

[′kē‚lȯid] (medicine) A firm, elevated fibrous formation of tissue at the site of a scar.

Keloid

 

a tumor-like growth of the fibrous connective tissue of the skin.

The causes of keloid development are not clear. Certain persons have a predisposition to their development. A distinction is made between true (spontaneous) keloids, which develop on visibly unchanged skin, and false keloids, which develop at the site of a scar after trauma (mechanical, thermal, chemical) or purulent disease (a furuncle, for example). A true keloid is a slightly elevated formation (5–8 mm above the skin surface) of whitish or pinkish color and dense consistency, with a smooth, shiny surface. Keloids appear most often in young people in the area of the chest, neck, and pinnae; and more rarely, on the face and limbs. Growth takes place for several weeks or sometimes months, after which the dimensions of the keloid remain unchanged throughout the patient’s lifetime. Treatment consists of injections of hyaluronidase and vitreous body; administration of vitamins PP, B2, and C; electrophoresis of potassium iodide; paraffin therapy; and X-ray therapy.

keloid


keloid

 [ke´loid] a sharply elevated, irregularly shaped, progressively enlarging scar, due to excessive collagen formation in the corium during connective tissue repair. It is a benign tumor that usually has its origin in a scar from surgery or a burn or other injury; keloids are generally considered harmless and noncancerous, although they may produce contractures or cosmetic alterations that affect body image. Ordinarily they cause no trouble beyond an occasional itching sensation. Surgical removal is not usually effective because it results in a high rate of recurrence. However, intralesional injection of steroids, cryotherapy, and x-ray therapy often are of substantial help. When x-ray therapy is employed, care must be taken not to destroy the surrounding healthy tissue. adj., adj keloid´al.Keloid. From Dorland's, 2000.

ke·loid

(kē'loyd), A nodular, firm, movable, nonencapsulated, often linear mass of hyperplastic scar tissue, tender and frequently painful, consisting of wide irregularly distributed bands of collagen; occurs in the dermis and adjacent subcutaneous tissue, usually after trauma, surgery, a burn, or severe cutaneous disease such as cystic acne, and is more common in blacks. Synonym(s): cheloid [G. kēlē, a tumor (or kēlis, a spot), + eidos, appearance]

keloid

(kē′lŏyd) [Gr. kele, tumor, + eidos, form, shape] KELOIDAn exuberant scar that forms at the site of an injury (or an incision) and spreads beyond the borders of the original lesion. The scar is made up of a swirling mass of collagen fibers and fibroblasts. Grossly it appears to have a shiny surface and a rubbery consistency. The most common locations for keloid formation are on the shoulders, chest, and back. See: illustration

Treatment

The injection of a corticosteroid sometimes helps the lesion regress. Freezing the tissue with liquid nitrogen, applying pressure dressings, treating it with lasers, excising it surgically, or a combination of these treatments may be used, but recurrences are frequent.

acne keloid

A keloid that develops at the site of an acne pustule. illustration

keloid

An abnormal healing response causing scars that are markedly overgrown, thickened and disfiguring. Keloids are commoner in black people than in white and may follow any injury or surgical incision. Surgical removal of keloids is followed by even more extensive keloid formation but they can be helped by injection of corticosteroid drugs. Untreated keloids eventually flatten.
