Coin-rubbing injuries.

Two cases of injuries caused by "coin rubbing" (Kuasha) are presented. In one case these injuries were confined to the neck, raising the possibility of strangulation, and in the other to the trunk and limbs, suggesting torture. Coin rubbing is practiced by most South-East Asian cultures, which believe that it relieves the symptoms of headache, fever, and flu. The causation and characteristics of these injuries and their medicolegal importance are discussed.
