Auricular hematomas are caused by direct trauma to the pinna.The torn perichondrial vessels bleed between the detached perichondrium and underlying cartilage. Interestingly, the presence of a subperichondrial hematoma has been found to stimulate new and often asymmetric cartilage to form. This deformity, which is often referred to as cauliflower ear or wrestler’s ear, is often considered a badge of honor among wrestlers and rugby players.
