[Adult-onset Still's disease. Diagnosis, differential diagnosis and treatment].

The article describes two cases of adult Still's disease and reviews the relevant literature. Adult onset Still's disease is characterized by high peaks of fever, arthritis, arthralgia, rash, increased erythrocyte sedimentation rate, leucocytosis, liver dysfunction and negative tests for antinuclear antibodies and rheumatoid factors. Still's disease should be regarded as a possible differential diagnosis in adult patients who present such features.
