A case of primary localized amyloidosis of the urinary bladder is reported. A 57-year-old male who complained of macrohematuria visited our hospital. Cystoscopic examination revealed a broad basic tumor from the anterior wall to the right wall. Suspecting a bladder tumor we performed a transurethral resection. However, the histopathological examination of the specimen revealed amyloid deposition and no malignant changes. Serum electrophoresis pattern was normal and urinary Bence-Jones protein was negative. Neither rectal nor gastric biopsy revealed amyloids. From these findings, we made a diagnosis of the primary localized amyloidosis of the urinary bladder. We collected 42 cases from the Japanese literature and discuss the clinical features of this disease.
报告一例膀胱原发性局限性淀粉样变性病。一名57岁男性因肉眼血尿前来我院就诊。膀胱镜检查发现从前壁到右壁有一个基底较宽的肿瘤。怀疑是膀胱肿瘤，我们进行了经尿道切除术。然而，标本的组织病理学检查显示有淀粉样沉积，无恶性改变。血清电泳图谱正常，尿本-周蛋白阴性。直肠和胃活检均未发现淀粉样物质。根据这些发现，我们诊断为膀胱原发性局限性淀粉样变性病。我们从日本文献中收集了42例病例，并讨论了该疾病的临床特征。
