We describe a case of localised amyloidosis of the distal ureter in a 66-year-old lady who presented with intermittent haematuria. Ureteric transitional cell carcinoma was strongly suspected from the clinical and radiological features, and subsequent nephroureterectomy was performed. Histology revealed nodular eosinophilic deposits in the ureteric wall, with the staining characteristics of amyloid. The literature is reviewed, and conservative surgery is advocated, based on a greater awareness together with improved intraoperative diagnosis of this rare lesion.
我们描述了一例66岁女性远端输尿管局限性淀粉样变性病例，该患者表现为间歇性血尿。根据临床和影像学特征，强烈怀疑为输尿管移行细胞癌，随后进行了肾输尿管切除术。组织学检查显示输尿管壁有结节状嗜酸性沉积物，具有淀粉样蛋白的染色特征。本文对相关文献进行了综述，并基于对这种罕见病变的更多认识以及术中诊断的改善，主张采用保守手术。
