摘　　要：目的 分析后肾腺瘤的临床、病理及影像学特征,并探讨其诊断及鉴别诊断.方法 收集2例经病理诊断为后肾腺瘤的病例,复习国内外相关文献报道,结合临床、影像学、病理组织学及免疫组织化学特征对后肾腺瘤进行分析总结.结果 影像学检查示乏血供性病变.形态学表现肿瘤细胞呈胚胎样,体积小且大小一致,含少量嗜酸性细胞质,染色质细腻,核仁不明显,无病理性核分裂象,瘤细胞呈小管状、腺泡状,局部可见乳头状增生,砂粒体可见;免疫组化：波形蛋白及细胞角蛋白呈不同程度阳性表达.结论 后肾腺瘤为一种少见的肾脏肿瘤,发生于单侧肾脏,临床及影像学特征不明显,最终诊断需病理确诊.Objective To study the radiological,clinicopathological features and prognosis of metanephric adenoma.Methods Two cases were selected,which underwent partial and radical renal resection.Examined the microscopic,immunohistochemical and radiological features of 2 metanephric adenoma cases.All patients were examined by ultrasound,CT and magnetic resonance imaging.Results They were lack of blood supply in imaging examination.The tumor cells were uniform with few eosinophilic cytoplasm.The chromatin is exquisite and lack pathological mitotic figure.The tumor cells were arranged in small tube or alveolar and locally showed papillary hyperplasia.Sometimes psammoma bodies were shown..Metanephric adenoma showed positive to Vimentin and CK.Conclusions Metanephric adenoma is a rare renal tumor mostly occur in single renal.And its morphological characteristic is diversity,so it＆#39;s easy being misdiagnosed as malignant tumor.The pathologists should be careful and have the concept of metanephric adenoma when diagnosis.
