A 7-year-old girl with polyarticular type juvenile rheumatoid arthritis

(JRA) presented with acute onset of right hip pain with limited range of

motion and fever within the past two days. She had received etanercept for

more than one year.

Percutaneous arthrocentesis was performed and showed a white blood cell

count of 84150/muL in the synovial fluid, although the culture showed

negative results. The fever and right hip pain completely resolved after

antibiotic treatment.

Herein, the authors report the first case of septic monoarthritis of JRA

under etanercept treatment.
