title: [A case of localized amyloidosis of the ureter].
abstract: A case of localized amyloidosis of the ureter is reported. The patient was a 49-year-old female whose chief complaint was macrohematuria. Roentogenographic examination showed left hydronephrosis due to stenosis of left middle ureter. Left nephrouretectomy with cuff was performed with a diagnosis of the left ureteral tumor, and pathological examination revealed localized amyloidosis of the left ureter. Localized amyloidosis of the ureter is a rare lesion, and this is the twenty-first case reported in the Japanese literature. Review of the literature revealed that it is difficult to differentiate this lesion from other ureteral tumors by roentgenographic examination, and it is important to perform preoperative or intraoperative biopsy of ureteral tumors if benign diseases cannot be ruled out.
