Amyloidosis is defined as extracelluar deposition of amyloid, a fibrillary protein in one or more body sites. It can involve genito-urinary tract, primarily or secondarily, but isolated primary bladder amyloidosis is an extremely rare presentation. We herein report a rare case of 48-year-male patient presented with symptoms mimicking carcinoma urinary bladder especially painless haematuria. Transurethral resection of the mass was done in one sitting. The histopathological examination revealed to be a primary bladder amyloidosis. In the follow-up, patient had improvement in symptoms and no recurrence. We also briefly review the literature on primary bladder amyloidosis.
淀粉样变性被定义为淀粉样蛋白（一种纤维状蛋白质）在一个或多个身体部位的细胞外沉积。它可原发性或继发性累及泌尿生殖道，但孤立的原发性膀胱淀粉样变性是一种极为罕见的表现形式。我们在此报告一例罕见的48岁男性患者，其症状类似膀胱癌，尤其是无痛性血尿。该肿块一次经尿道切除。组织病理学检查显示为原发性膀胱淀粉样变性。在随访中，患者症状改善且无复发。我们还简要回顾了关于原发性膀胱淀粉样变性的文献。
