[Localized amyloidosis of the ureter: report of a case].
A case of primary amyloidosis of the ureter is presented. The patient was a 48-year-old woman with a 5-year history of asymptomatic macrohematuria. Roentgenographic examination showed left hydronephrosis and stenosis of the left distal ureter. Histological examination of the biopsied specimen during the operation revealed no malignancy; and, left partial ureterectomy and uretero- vesiconeostomy was performed. Congo red stain proved amyloid deposition after surgery. Rectal biopsy was negative for amyloid; and, other laboratory findings were within normal range. Thus it was diagnosed as a primary localized amyloidosis of the ureter. Importance of intraoperative histologic examination was discussed. This is the 22nd case in the literature.
