Pinna or auricular hematoma, is most commonly caused by blunt trauma to the ear. The cartilage of the ear derives its blood supply from the skin. When this skin gets pulled up because of accumulation of blood following trauma, the cartilage is deprived of nutrition and dies. The ear cartilage contracts and shrivels, giving the appearance of a cauliflower. This appearance is permanent once the cartilage death occurs. It is commonly seen in wrestlers, boxers, and martial artists, and therefore it is also called boxers ear or wrestlers ear.
