It was originally called systemic-onset juvenile rheumatoid arthritis or Still's disease.

Predominantly extra-articular manifestations like high fevers, rheumatic rash, enlargement of the liver and spleen, enlargement of the lymph nodes, and anemia. Other manifestations include inflammation of the pleura, inflammation of the pericardium, inflammation of the heart's muscular tissue, and inflammation of the peritoneum are also seen.[citation needed] It is sometimes called "juvenile-onset Still's disease" to distinguish it from adult-onset Still's disease. However, there is some evidence that the main difference between two conditions is the age of onset.[2]
