A 54-year-old man visited our hospital with right incidentally-found renal tumor detected by ultrasonography. Computed tomography, magnetic resonance imaging and angiography showed a small tumor, 1.5 cm in size, at the upper portion and a simple cyst, 4 cm in size, at the lower pole of the right kidney. We enucleated the small tumor and aspirated the cyst with outer part resection of the cyst wall. Pathological findings of the tumor showed renal cell carcinoma, alveolar type, common type, clear cell subtype, G1, pT1, INF-alpha. Microscopic appearance of the excised cyst wall also revealed sheets of renal cell carcinoma inside the wall. Therefore, two weeks after the first operation, we performed right radical nephrectomy. The resected specimen had severe inflammation without any evidence of residual tumor. Eight months after the nephrectomy, no recurrence has occurred.
一名54岁男性因超声偶然发现右侧肾肿瘤前来我院就诊。计算机断层扫描、磁共振成像和血管造影显示，右肾上部有一个大小为1.5厘米的小肿瘤，下极有一个大小为4厘米的单纯性囊肿。我们摘除了小肿瘤，并对囊肿进行穿刺抽吸，同时切除囊肿壁的外部部分。肿瘤的病理检查结果显示为肾细胞癌，肺泡型，常见型，透明细胞亚型，G1，pT1，INF-α。切除的囊肿壁的显微镜检查也显示壁内有肾细胞癌片。因此，在第一次手术后两周，我们进行了右侧根治性肾切除术。切除的标本有严重炎症，无残留肿瘤迹象。肾切除术后八个月，未发生复发。
