Abstract：
Metanephric adenoma (MA) is a rare embryonal epithelial tumor that is often diagnosed incidentally. A definitive diagnosis can only be made postoperatively based on the pathological findings. This case report discusses the rare occurrence of a metanephric adenoma, the symptoms it can present with, and the diagnosis, treatment, and immunological staining needed to differentiate metanephric adenoma from other types of renal tumors. In this study, a 37-year-old female presented to the emergency room for vague right lower quadrant pain (RLQ) and underwent imaging that showed a lesion on the lower pole of the left kidney. A subsequent biopsy of the lesion showed a low-grade renal epithelial neoplasm favoring metanephric adenoma. The patient successfully underwent a left partial nephrectomy to remove the tumor, which required no further treatment after resection. Due to the rarity of the tumor, it requires immunohistology to differentiate from other renal tumors such as Wilm\'s tumor and renal cell carcinoma. This case report aims to recognize proper workup, diagnosis, and treatment to achieve a positive outcome in the setting of this rare tumor.
摘要：
后肾腺瘤（MA）是一种罕见的胚胎上皮性肿瘤，通常是偶然诊断的。只能根据病理结果在术后做出明确的诊断。该病例报告讨论了罕见的后肾腺瘤，它可以呈现的症状，和诊断，治疗,和免疫染色需要区分后肾腺瘤和其他类型的肾肿瘤。在这项研究中,一名37岁女性因模糊的右下腹疼痛(RLQ)出现在急诊室,并接受了影像学检查,显示左肾下极有病变.随后的病变活检显示低度肾上皮肿瘤有利于后肾腺瘤。病人成功地接受了左肾部分切除术切除肿瘤,切除后无需进一步治疗。由于肿瘤的稀有性,它需要免疫组织学来区分其他肾肿瘤，如Wilm's肿瘤和肾细胞癌。本病例报告旨在认识到适当的检查，诊断,以及在这种罕见肿瘤的背景下获得积极结果的治疗。
