The occurrence of malignant neoplasms of the urinary tract in patients below the age of 40 years is rare. Nevertheless, finding masses with suspicious malignant appearance in young patients should alert the examiner particularly against the background of reported cases of urothelial or urachal carcinoma in childhood or adolescence. This report presents the case of a 25-year-old male patient with recurrent urolithiasis due to cystinuria. During elective stone therapy via ureteroscopy a tumor of distinct malignant appearance was conspicuous and was immediately resected. The histopathological findings revealed the diagnosis of a nephrogenic adenoma.
40岁以下患者发生泌尿系统恶性肿瘤的情况较为罕见。然而，在年轻患者中发现具有可疑恶性外观的肿块时，尤其是在有儿童或青少年期尿路上皮癌或脐尿管癌报告病例的背景下，检查者应予以警惕。本报告介绍了一名25岁男性患者，因胱氨酸尿症反复发生尿路结石。在通过输尿管镜进行择期结石治疗期间，一个具有明显恶性外观的肿瘤十分显眼，并立即进行了切除。组织病理学检查结果显示诊断为肾源性腺瘤。
