We present a 74-year old woman who was hospitalized because of typical
spiking fever, evanescent rash, polyarthralgia, lymphadenopathy, and
marked elevation of serum transaminases and lactate dehydrogenase (LDH
) due to adult-onset Still's disease (AOSD) with submassive hepatic ne
crosis. All of the symptoms and abnormal laboratory findings were dram
atically improved after treatment with prednisolone. The clinical cour
se of this patient indicates that AOSD with severe hepatic necrosis ca
n successfully be treated with early administration of corticosteroid,
although it remains unknown whether the disease can remain in remissi
on with no or minimal treatment.
