Primary lymphoid neoplasms of the urinary tract are exceedingly rare, with only 21 cases being reported and comprising less than 5% of all primary extranodal lymphomas. We report a case of a 45-year-old man who presented with right flank pain and weight loss, and who was found to have a stricture in the right lower ureter causing ureteral obstruction. Histopathology revealed lower ureteric non-Hodgkin lymphoma, which, on further evaluation, was found to be isolated ureteric lymphoma. The patient was doing well after six cycles of R-CHOP chemotherapy. This case is being reported as a rare cause of distal ureteric obstruction.
泌尿系统原发性淋巴肿瘤极为罕见,仅有21例报道,占所有原发性结外淋巴瘤的比例不到5%。我们报告一例45岁男性,表现为右侧腰痛和体重减轻,发现右下腹输尿管狭窄导致输尿管梗阻。组织病理学显示下段输尿管非霍奇金淋巴瘤,进一步评估发现为孤立性输尿管淋巴瘤。该患者在接受6个周期的R-CHOP化疗后情况良好。本文报道此病例作为远端输尿管梗阻的罕见病因。
