Immunoglobulin G4-related disease (IgG4-RD) is a systemic immune-mediated fibroinflammatory condition that can mimic several diseases and can present as a malignant tumor. We present a case of a 53-year-old woman who presented with a right upper ureteric mass. On pathologic evaluation, a diagnosis of IgG4-RD was made. In the absence of preoperative biopsy and other clinical manifestations, preoperative clinical diagnosis remains challenging and high index of suspicion and accurate pathological evaluation may help in avoiding misdiagnosis.
免疫球蛋白 G4 相关疾病（IgG4-RD）是一种系统性免疫介导的纤维炎症性疾病，可模拟多种疾病，并可表现为恶性肿瘤。我们报告了一例 53 岁女性，表现为右输尿管上段肿块。病理评估诊断为 IgG4-RD。由于术前未行活检及其他临床表现，术前临床诊断仍具有挑战性，高度怀疑和准确的病理评估有助于避免误诊。
