What is the term for discoloration behind the ears?

Battle's sign refers to the discoloration that appears behind the ears and is an important clinical indicator often associated with skull fractures, particularly those involving the temporal bone. This discoloration is due to the accumulation of blood in the subcutaneous tissue, which can occur as a result of trauma. Recognizing Battle's sign is crucial for healthcare professionals as it can indicate a serious head injury and may require immediate medical attention.

In contrast, other terms such as raccoon eyes describe similar discoloration around the eyes, often resulting from the same types of injuries but not specifically behind the ears. Contusion and bruising refer more generally to any localized swelling or discoloration due to blood vessels breaking under the skin, without the specific anatomical reference to the areas around the ears. These terms do not pinpoint the particular clinical significance that Battle's sign carries regarding potential cranial injuries. Thus, understanding the specific context and implications of Battle's sign helps differentiate it from other forms of trauma-related discoloration.
