Cauliflower ear is an irreversible condition that occurs when the external portion of the ear is hit and develops a blood clot or other collection of fluid under the perichondrium. This separates the cartilage from the overlying perichondrium that supplies its nutrients, causing it to die and resulting in the formation of fibrous tissue in the overlying skin. As a result, the outer ear becomes permanently swollen and deformed, resembling a cauliflower, hence the name.
The condition is common in martial arts such as Brazilian jiu-jitsu, wrestling, boxing, kickboxing, judo, sumo, or mixed martial arts, and in full-contact sports such as rugby league or rugby union.
