Renal amyloidosis complicating bladder carcinoma associated with supra renal insufficiency

Abstract EN

A 61-year-old white man was admitted for evaluation of hematuria.

His medical history revealed endoscopic resection of bladder carcinoma 10 years earlier.

A diagnosis of relapse of this carcinoma was made.

Few months later, he developed low blood pressure and the nephrotic syndrome.

Examination of a renal biopsy specimen showed amyloid deposits.

Results of immunofluorescence were positive for AA protein.

Furthermore, laboratory tests demonstrated suprarenal insufficiency probably due to amyloidosis.

A diagnosis of bladder carcinoma- induced amyloidosis of the kidneys and suprarenal glands was made since no other identifiable cause for AA amyloidosis was found.
