title: Two cases of acute poststreptococcal glomerulonephritis superimposed on rheumatoid arthritis.
abstract: Recently, the rheumatoid factor (RF) has been postulated to play a role in the development of acute poststreptococcal glomerulonephritis (APSGN). However, there are few reports in which APSGN is superimposed on rheumatoid arthritis (RA). Two patients are reported in this paper who showed atypical renal histopathological findings as APSGN. It was suggested that renal histopathological finding might become different from those of typical APSGN when it is superimposed on RA.
