Some opinions of the clinical paterns that are easy wrong with the systemic rheumatoid arthritis in children

ABSTRACT

The diagnosis of systemic onset JRA may be very difficult, especially at the onset of the disease. A proposes of three cases with systemic pattern, we would like to emphasize this opinion. The first case is an acute lymphoblastic leukemia with RF positive. The second is really a systemic JRA that was the same as Kawasaki disease. And the third is a systemic manifestation of an auto- immune disease class II (non organo specific) with FR and ANA positive. Rheumatoid factors are neither specific for nor diagnosis of JRA, especially at systemic onset JRA. Systemic onset JRA is a diagnosis of exclusion.
