Abstract

A 60-year-old Asian woman presented with a 1-year history of painless gross hematuria. She had no prior urologic history and no other medical problems. Her physical examination, urine cytology, and computed tomography scan were normal. Cystoscopy demonstrated several punctate areas of erythema within the bladder. Biopsies revealed amyloidosis, and immunohistochemical staining of the specimens defined the process as amyloid AA (often called secondary amyloidosis). The workup for systemic conditions associated with amyloid AA was negative. This represents an unusual case of primary localized AA-type amyloidosis of the bladder.
