Horse bite injury.

Bite wounds are relatively frequent, the order of frequency being, dogs, cats and humans. The clinical importance of other types of bites depends on the severity of the injury or any subsequent infection. We report on the case of a woman bitten on her thigh by a horse, producing severe haematoma, fat necrosis and muscle rupture, without an external wound. We emphasize the importance of the ultrasound examination in the evaluation of the extent of the crush injury.
