Amyloidoma of the Bladder Mimicking a Bladder Tumor

Abstract

Primary amyloidosis of the bladder is a rare disease reported in about 200 cases in the literature (1). Generally, this patients are admitted to the hospital with painless gross hematuria and lower urinary tract symptoms. Especially, symptomatic, radiological and cystoscopic findings of bladder amylodidosis and bladder cancer are similar. Neoplasia, hemorragic cystitis and lyphoma should be considered in differential diagnosis. Pathological diagnosis is imperative for the definitive diagnosis. Its pathophysiology is unknown, the prognosis is usually good and there is no specific treatment. Herein, we present the diagnosis and treatment of bladder amyloidosis, which is rare and mimics bladder cancer.
