What is another name for Still's disease?

Still's disease, also known as systemic juvenile idiopathic arthritis (JIA), is often referred to as juvenile rheumatoid arthritis, particularly in its earlier classification. The condition is characterized by systemic inflammation and joint pain, typically affecting children under the age of 16. It presents with systemic features such as fever, rash, and lymphadenopathy, in addition to joint involvement.

The term "juvenile rheumatoid arthritis" is an older term that has largely fallen out of favor but is still commonly recognized and sometimes used interchangeably with Still's disease in practice. This distinction is important as juvenile idiopathic arthritis encompasses different subtypes, including systemic and oligoarticular, and Still's disease is specifically the systemic form.

The other terms listed, such as adult rheumatoid arthritis or chronic granulomatous disease, refer to different conditions with distinct pathophysiological mechanisms and clinical presentations, making them incorrect in the context of this question. Pediatric systemic arthritis, while it captures the systemic nature and pediatric age group, is not as widely recognized or utilized as Still's disease or juvenile rheumatoid arthritis. Therefore, the best answer remains juvenile rheumatoid arthritis, reflecting the historical and common terminology surrounding Still's disease.
