Bilateral amyloidosis of the ureter associated with carcinoma.

We report a case of coexisting amyloid and neoplasm in a localized ureteral lesion. This case also represents the third reported instance of sequential bilateral ureteral amyloidosis. Right nephroureterectomy revealed amyloid and an in situ focus of low grade transitional cell carcinoma. Three years later amyloid in the distal left ureter was resected and the gap was bridged by a bladder hitch and Boari flap. Subsequent followup has been uneventful.
