Abstract
-
Secondary amyloidosis is characterized by accumulation of an amorphous proteinous material in the various tissue and organs with infectious disease or inflammatory disease. Symptoms of the amyloidosis are variable according to the involved organs. Reactive amyloidosis of bladder in rheumatoid arthritis (RA) is a rare condition with hematuria in the most cases. However, we report two cases of patients with RA, who have frequency due to secondary amyloidosis of bladder without hematuria. Therefore secondary amyloidosis of urinary bladder should be considered as a possible cause of frequency in patients with long-term RA.
