摘要
目的探讨肾类癌的临床病理特征。方法对1例肾类癌的临床资料进行分析并结合文献复习。结果 59岁女性患者体检时偶然发现无症状左肾肿物,患者无类癌综合征。CT示左肾下极肿物,直径约3.8 cm,边界清楚,强化不明显。患者行经腹膜后途径根治性左肾切除术。免疫组织化学染色显示突触素,CD56,神经元特异性烯醇酶,波形蛋白,CK18呈阳性。病理诊断:左肾类癌T1a期。术后未行辅助治疗,随诊17个月未见肿瘤复发或转移。结论肾类癌极其罕见,确诊依赖病理学及免疫组织化学检查。局限性肾类癌的治疗首选完整的外科切除,其预后相对较好。
Objective To discuss the clinicopathological characteristics of renal carcinoid tumor.Methods One case of renal carcinoid tumor was reported and related literatures were reviewed.Results A 59-year-old woman,showing no symptoms of carcinoid syndrome,presented an asymptomatic left-sided renal mass incidentally in a comprehensive medical examination,during which a 3.8 cm poorly enhanced,well-defined mass was observed in the lower pole of the left kidney on CT.The patient underwent a left radical nephrectomy through the retroperitoneal approach.Immunohistochemistry revealed positive staining for Synaptophysin,CD56,NSE,Vimentin,and CK18.The case was diagnosed as left renal carcinoid tumor T1a.The patient received no adjuvant therapy and was alive without reoccurrence or metastasis 17 months after diagnosis and surgery.Conclusion As an extremely rare disease,renal carcinoid tumor can only be diagnosed with pathological and immunohistochemical examination.Complete surgical excision is the preferred treatment for localized renal carcinoid tumor,with relatively optimistic prognosis.
