Boxer's ear is a condition that occurs due to repeated blows to the ear during boxing matches. It causes swelling of the outer ear and can lead to permanent disfiguration if not treated properly. Some synonyms of boxer's ear include cauliflower ear, wrestler's ear, and hematoma auris. Cauliflower ear is the most commonly used term, as it describes the distinct shape that the ear takes on as a result of repeated trauma. Wrestler's ear is used to describe the same condition in wrestlers. Hematoma auris is a medical term used to describe the accumulation of blood within the ear cartilage.
