Abstract
- Since localized amyloid deposits of the ureter were first described by Lehmann in 1937, approximately 90 cases have been reported. Isolated primary amyloidosis of the ureter is a rare disease, and its diagnosis cannot be made by radiologic findings. Because of radiographic similarity to transitional cell carcinoma, these lesions are often clinically mistaken for malignancies, and nephroureterectomy is usually performed. Here, we report a case of localized ureteral amyloidosis with osseous metaplasia, which was managed successfully by renal sparing segmental resection with the bladder Boari flap.
