Metanephric adenoma is a rare benign renal tumour. We are reporting one histologically proven such case in a 23 year old male from Afghanistan. He presented with severe right flank pain since 3 weeks. Nephrectomy was done and histopathology was consistent with the diagnosis of metanephric adenoma. This novel renal mass has been reported to have benign clinical course despite its symptomatic presentation and large tumour size. There is no distinguishing radiological feature with can differentiate it from malignant tumours. So far, a uniformly benign clinical course has been associated with Metanephric adenoma, but given its relatively recent identification and rarity and the lack of clinical, radiographic, or cytologic means to establish a definite diagnosis, Metanephric adenoma remains primarily a pathologic diagnosis.
后肾腺瘤是一种罕见的良性肾肿瘤。我们报告一例经组织学证实的病例，患者为一名23岁来自阿富汗的男性。他自3周前开始出现严重的右侧腰痛。已行肾切除术，组织病理学结果与后肾腺瘤的诊断相符。据报道，这种新型肾肿物尽管有症状表现且肿瘤体积较大，但临床病程呈良性。目前尚无能够将其与恶性肿瘤区分开来的特征性影像学表现。到目前为止，后肾腺瘤的临床病程一致为良性，但鉴于其发现时间相对较近且较为罕见，以及缺乏用于明确诊断的临床、影像学或细胞学方法，后肾腺瘤主要仍为病理诊断。
