cauliflower ear cau·li·flow·er ear (kô'lĭ-flou'ər)
An ear that is swollen, hardened, and deformed from extravasation of blood following repeated blows.
A boxer's or wrestler's ear deformed by injuries and accumulated scar tissue (1900s+)
distortion of the cartilage of the outer ear as the result of an injury. If the injury causes bleeding between the cartilage and the skin, it produces a smooth and rounded purplish swelling. Accumulated clotted blood, if not removed, is transformed into scar tissue, causing permanent, odd-shaped thickening of the outer ear. Because boxers' and wrestlers' ears are subjected to so much pounding abuse, cauliflower ear is often associated with those sports.
