Potential forensic implications of kerokan therapy – a traditional Indonesian therapy associated with neck bruising

Kerokan is a traditional Indonesian treatment involving abrading the skin over various parts of the body with a blunt object such as a coin or a piece of ginger which may create suspicious injuries. Here, the case of a 30-year-old woman who had undergone kerokan therapy is reported. She was complaining of retro-sternal pain and epigastric discomfort and subsequently became markedly short of breath and died. The observation of injuries predominantly located around the neck initiated a police investigation and forensic autopsy. Scattered abrasions, blisters and bruises were present on the forehead, the bridge of the nose extending to the ala, the upper and anterior aspect of the chin and the sternal notch, with discrete fresh and scabbed abrasions around the neck, over the sternum and on the backs of both hands. There were, however, no facial or conjunctival petechiae and no bruising of the underlying strap muscles, or fractures of the hyoid bone or thyroid cartilage. Histology revealed that myocarditis was the cause of death. Traditional practices may cause unusual bruises, abrasions, blisters and burns that may raise suspicion of inflicted injury from an assault. Knowledge of the manifestations of socio-ethnic practices such as kerokan is important in the evaluation of trauma in specific cultural groups.
