肾嗜酸性细胞瘤11例的诊治体会及文献复习

Diagnosis and treatment of renal oncocytoma of 11 cases and literature review

目的:探讨肾嗜酸性细胞瘤的诊治方法,提高肾嗜酸性细胞瘤的诊疗水平。方法:总结分析11例肾嗜酸性细胞瘤患者的临床资料,并复习相关文献。结果:1例行腹腔镜肾根治性切除术,1例行经腰肾根治性切除术,9例行腹腔镜肾部分切除术。所有患者术后病理均证实为肾嗜酸性细胞瘤。术后随访7～60个月,平均26个月,无复发或转移。结论:肾嗜酸细胞瘤是一种少见的良性肿瘤,临床表现及影像学检查多不典型,易误诊为肾癌。对于可疑病例,应结合影像学检查、术前穿刺及免疫组化结果,综合评判。

objective:To summarize the experience in diagnosis and treatment of 11 cases of renal oncocytoma.Methods:The clinical data of 11 cases of renal oncocytoma confirmed surgically and pathologically were analyzed ret?rospectively. The literatures about this disease were reviewed.Results:Two patients were treated with radical ne?phrectomy. Partial nephrectomy was performed on the rest 9 cases. Pathologically,the diagnosis of renal oncocytoma was made after surgery. After a median follow-up period of 26 months(7 to 60 months),there was no recurrence or metastasis from oncocytoma.Conclusion:Renal oncocytoma is a rare benign tumor,and difficult to differentiate from renal cancer with asymptomatic symptom and image examination. The diagnosis can be established on radiological im?aging techniques,renal mass biopsy and immunohistochemistry.
