SYSTEMIC-ONSET JUVENILE RHEUMATOID ARTHRITIS (STILL'S DISEASE)

Also known as systemic-onset juvenile chronic arthritis. Still's disease presents with systemic (bodywide) illness including high intermittent fever, a salmon-colored skin rash, swollen lymph glands, enlargement of the liver and spleen, and inflammation of the lungs (pleuritis) and around the heart (pericarditis). The arthritis may not be immediately apparent but, once apparent, it may persist after the systemic symptoms are gone.
