A case of localized amyloidosis of the urinary bladder is reported. A 82-year-old woman visited our hospital with the chief complaint of miction pain and residual urine sensation. Cystoscopic examination revealed a broad-based and nonpapillary tumor without bleeding on the right lateral wall. A transurethral biopsy of this tumor was performed. A histopathological examination with H.E. and Congo red stains demonstrated amyloid deposition in the submucosal layers of the vesical wall. Rectal biopsy and other findings suggested no deposition of amyloid in other organs. On the basis of these findings, we made a diagnosis of localized amyloidosis of the urinary bladder. To the best of our knowledge, the present case is the 23rd of localized amyloidosis of urinary bladder in Japan. The patient was asymptomatic after biopsy. We discuss the clinical features and management of this disease.
