title: Localized amyloidosis of the urinary bladder, clinically masquerading as bladder cancer.
abstract: Amyloidosis is characterized by extracellular deposition of a proteinaceous, hyaline material. Localized deposition of amyloid in individual organs is uncommon. It can occur in the absence of systemic involvement. Herein, we describe two cases of localized amyloidosis of the urinary bladder, which clinically, radiologically, and on cystoscopy masqueraded as bladder cancer. A diagnosis of amyloidosis in both these cases was ascertained on biopsy, supplemented with special stains.
