Amyloidosis in the bladder: Three cases with different appearance

Abstract

Amyloidosis refers to a number of diseases characterized by extracellular deposition of misfolded proteins, called amyloid fibrils, in the tissues and organs of the body. Amyloidosis in the bladder is a generally localized, rare condition, with approximately 200 cases reported in the literature. This report presents three cases of amyloidosis in the bladder, two of which had coexisting transitional cell carcinoma. Evaluation for systemic disease is recommended in patients with newly discovered amyloidosis, even if first recognized in an area with the localized form, as in the bladder.
