A Rare Case Report: The Cause of Painless and Gross Hematuria Is Primary Amyloidosis of the Bladder

Primary amyloidosis of the urinary bladder is a rare disease, with only approximately 200 cases re-
ported in the literature. Localized bladder amyloidosis is a rare disease that mimics neoplasia clinical-
ly, cystoscopically, and radiologically. The physiopathology is unknown, the prognosis is usually good
and there is no specific treatment. Here we present a case report of the bladder amyloidosis, diagnosis
and management of this rare condition.
