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.
