6例后肾腺瘤的临床与病理学特点分析

目的 :探讨后肾腺瘤(metanephric denoma,MA)的临床及病理学特点。 方法 :结合文献回顾性分析6例MA患者的临床和病理资料。男4例,女2例。年龄33～66岁,平均51岁。右肾4例,左肾2例;仅1例表现为腰痛不摘要 目的 :探讨后肾腺瘤(metanephricdenoma,MA)的临床及病理学特点。 方法 :结合文献回顾性分析6例适、乏力,无其他阳性发现。6例均经B超、CT诊断为肾肿瘤。 结果 :5例行根治性肾切除,1例行肿瘤剜除术。肿瘤平均直径4cm。病理学特点:MA细胞均匀一致,排列成密集的小管状、腺样结构,胞浆少,无明显异形性,核分裂像罕见。免疫组化WT1(+),而EMA和CK7(-)。1例肿瘤局部出现乳头状腺癌成分。5例获随访5～24个月,均无瘤生存。 结论 :后肾腺瘤是一种罕见的肾脏原发上皮源性肿瘤,了解其临床及病理特点有助于该肿瘤的准确诊断。对该肿瘤治疗多采取保留肾单位的手术,但其生物学行为及细胞起源的不确定性决定对该病患者需进行长期的随访观察。
