[Still's disease in the adult (author's transl)].

Four new cases of adult Still's disease have been observed in the past three years. Clinical and biological features are high fever, polyarthralgia, macular rash on forearm, pericarditis, splenomegaly, lymphadenopathy, alopecia, anemia, hyper-leucocytosis, raised ESR. Transient neurological findings may also be observed with abnormal reflexes, cranial nerve paralysis. High dose steroids treatment can be used in case of systemic involvement. The long term prognosis is usually good with treatment. In conclusion, the diagnosis of Still's disease is essentially clinical and should not be mistaken for septicemia.
