Cases of a Borderline Pathology That Can Mimic Bladder Cancer: Primary Amyloidosis of Urinary Bladder

Abstract

Amyloidosis is a disease characterised by accumulation of a fibrillar protein called amyloid in the extracellular space. The kidneys, ureters and the bladder can be affected in the urinary tract. However, primary amyloidosis of bladder is a rare entity. Macroscopic hematuria could be the first and only symptom of primary amyloidosis of the bladder; therefore, it has similar findings with urinary tract malignancies. Histopathological evaluation is mandatory for the diagnosis. Follow-up should always include cystoscopic evaluation as recurrence is expected in the natural course.
