[Pseudotumor amylosis of the bladder. Apropos of a case].

A 57 year-old patient with localized pseudo-tumoral amyloidosis of bladder is described. There was no past medical history. Hematuria was the main symptom. The treatment consisted in transurethral resection. Two recurrences occurred at 4 and at 6 years which were also treated by resections. Clinical and biological evaluation was normal. Localized pseudo-tumoral amyloidosis of the urinary tract is a rare affection of good prognosis. Lesions present as pseudo-tumoral masses which can be biopsied without any risk of hematuria. Investigations are required to eliminate a generalized amyloidosis or a malignant lymphoproliferation. Treatment should be as conservative as possible.
