OBJECTIVE
To report the first case in the literature of a primary large-cell undifferentiated carcinoma (LCUC) of the ureter with a very aggressive behavior and dismal prognosis.
CLINICAL PRESENTATION AND INTERVENTION
A 60-year-old woman with a history of intermittent macroscopic hematuria and mild to moderate right flank pain was admitted to the Department of Urology. Tissue biopsies and cytological samples were taken. Pathologic examination was consistent with LCUC.
CONCLUSION
LCUC of the ureter is an aggressive tumor with a high proliferation index. Patients might be diagnosed at an advanced stage. LCUC must be considered in the differential diagnosis of urinary tract pathologies.
目的

临床表现和干预
一名 60 岁女性，间歇性出现肉眼血尿和轻至中度右侧腰痛，收入泌尿科。进行了组织活检和细胞学样本采集。病理检查符合 LCUC。
结论
输尿管 LCUC 是一种侵袭性肿瘤，增殖指数高。患者可能在晚期被诊断。在鉴别诊断尿路病变时必须考虑 LCUC。
