目的:探讨后肾腺瘤的临床及病理特点。方法:报告1例后肾腺瘤患者的临床及病理资料.并复习相关文献予以讨论。结果:患者行根治性右肾切除术。镜下见肿瘤细胞大小一致,呈腺样及小管状排列.胞质少.细胞无明显异型性,核分裂像少见;免疫组织化学染色:WT1、Vimentin、CK、EMA均阳性.Syn、RCC、SMA、HMB45、CD10、CD34、CgA、Chr均阴性;病理学诊断符合后肾腺瘤特点。术后随访18个月.未见肿瘤复发和远处转移。结论:后肾腺瘤是一种罕见的来源于肾脏上皮组织的肿瘤,了解该肿瘤临床及病理特点有助于临床诊断及鉴别诊断。
Objective: To investigate the clinical and pathological features of posterior renal adenoma. Methods: The clinical and pathological data of one case of post-renal adenoma were reported, and the related literature was reviewed for discussion. Results: Patients underwent radical nephrectomy. Microscopically, the size of the tumor cells was uniform and showed adenoid and tubular arrangement with few cytoplasm.The cells showed no atypia and no mitotic figures.Immunohistochemical staining showed that both WT1, Vimentin, CK and EMA were positive.Syn, RCC, SMA , HMB45, CD10, CD34, CgA, Chr were negative; pathological diagnosis consistent with the characteristics of renal adenoma. The patients were followed up for 18 months and no tumor recurrence and distant metastasis were observed. Conclusion: Adenocarcinoma of the kidney is a rare tumor derived from renal epithelial tissue. It is helpful to understand the clinical and pathological features of this tumor in clinical diagnosis and differential diagnosis.
