recurrent multifocal primary amyloidosis of urinary bladder

Primary localized amyloidosis of bladder is rare. We report a case of recurrence of multifocal primary amyloidosis of urinary bladder. Cystoscopy revealed a diffuse left lateral wall lesion with normal surrounding mucosa. Histopathological examination of the specimen revealed urinary bladder amyloidosis with negative surgical margins. Recurrent urinary bladder amyloidosis was confirmed 3 months after the first resection. Close follow-up is recommended.
