Abstract

Still's disease (SD) is an acute systemic inflammatory disorder characterized by a triad of spiking fever, skin rash and polyarthritis. Hyperferritinemia is one of the major laboratory findings. A markedly increased serum ferritin level can be used not only as an indicator of disease activity but also as a  diagnostic marker of the disease. We report the case of a 15-year-old girl who was admitted to the hospital because of worsening joint pain and fever and diagnosed as SD.

Key words: Still's disease, ferritin, diagnosis
