[Acute hepatitis due to heatstroke]

The hepatic injury is a nearly constant event in the course of a heatstroke, which rarely evolves to a severe liver failure. In these cases, the patient's survival is conditioned to an early treatment and, sometimes, an orthotopic liver transplantation is needed. We report a case of severe acute hepatitis in a 17-year-old man, due to a heatstroke during a vigorous exercise in a training program. High ambient temperature and a long time without training predisposed to the development of heatstroke in this patient. Outcome was favourably, with a total recovery in a few weeks.
