Primary amyloidosis of the urinary bladder is a rare disease, with only approximately 200 cases reported in the literature. We herein present a case of amyloidosis of the urinary bladder with painful gross hematuria. Pelvic Computed Tomography showed uneven thickening of the bladder wall suspicious of neoplastic lesion. Cystoscopy and transurethral resection were performed. Congo-red staining confirmed amyloidosis it was. Postoperative recovery was good and close follow-up was recommended after discharged. Amyloidosis is usually benign, while it can masquerade as a malignancy. Doctors should consider it when imaging studies reveal a malignancy in bladder.
膀胱原发性淀粉样变性是一种罕见疾病，文献中仅报道了约200例病例。我们在此报告一例伴有疼痛性肉眼血尿的膀胱淀粉样变性病例。盆腔计算机断层扫描显示膀胱壁不均匀增厚，怀疑为肿瘤性病变。进行了膀胱镜检查和经尿道切除术。刚果红染色证实为淀粉样变性。术后恢复良好，建议出院后密切随访。淀粉样变性通常为良性，但可伪装成恶性肿瘤。当影像学检查显示膀胱有恶性肿瘤时，医生应考虑到这一点。
