The bladder involvement is a very unusual fact in systemic amyloidosis. The distinction of primary and systemic amyloidosis disease with bladder involvement (secondary bladder amyloidosis) is important to the urologist. Secondary amyloidosis of the bladder is a rare disease entity (approximately 20 cases published). We document a case of a woman with a large history of rheumatoid arthritis who developed severe macrohematuria. Diagnosis was done by biopsy that revealed amyloidosis, and it was confirmed with an immunohistochemical staining of the specimens that defined the process as amyloid AA (secondary amyloidosis).
