What are Tardieu spots?

• A. Large bruises caused by blunt trauma
• B. Dark, pinpoint petechial hemorrhages from strangulation injury
• C. Ruptured varicose veins
• D. Signs of bruising in child abuse

Answer: (B)

Tardieu spots refer to pinpoint petechial hemorrhages that are often associated with strangulation injuries. These small, dark spots are caused by the rupture of tiny blood vessels under the skin due to increased pressure and trauma, typically when blood flow is restricted, for example, during strangulation. The presence of these spots is significant in forensic medicine because they can indicate asphyxia or trauma related to strangulation, helping to differentiate between various causes of death in suspected homicide cases. Understanding the formation of Tardieu spots is essential for medical professionals, especially in emergencies or situations involving potential abuse, as they provide crucial information regarding the circumstances leading to a patient's injuries.
