[Rare cause of acute liver failure].

A rare cause of acute liver failure is adult onset Still's disease (AOSD), a systemic inflammatory disorder. We present the case of a 24-year-old woman who presented with acute liver failure necessitating high urgency liver transplantation. The diagnosis of AOSD was established in accordance with the Yamaguchi classification criteria, including arthralgia, fever, sore throat, rash and hepatosplenomegaly. The early detection and therapy of AOSD can possibly avoid the development of liver failure with a poor prognosis.
