BACKGROUND
Renal oncocytoma is the most common benign renal tumor, and papillary renal cell carcinoma is the second most common histologic subtype of renal cell carcinoma. Renal tumors containing different components such as papillary renal cell carcinoma and oncocytoma are extremely rare.
CASE PRESENTATION
A renal mass was incidentally detected in a 52-year-old Korean woman, and a computed tomographic scan showed a 32-mm multicystic mass with some calcifications in the lower pole of the right kidney. She underwent laparoscopic partial nephrectomy without any perioperative complications. We found a papillary renal cell carcinoma and an oncocytoma in a tumor mass.
CONCLUSIONS
The possibility of a mixed malignant tumor should be considered while treating benign tumors such as oncocytoma.
背景
肾嗜酸细胞瘤是最常见的肾良性肿瘤，而乳头状肾细胞癌是肾细胞癌第二常见的组织学亚型。含有乳头状肾细胞癌和嗜酸细胞瘤等不同成分的肾肿瘤极为罕见。
病例报告
一名52岁韩国女性偶然发现肾肿物，计算机断层扫描显示右肾下极有一个32毫米的多囊性肿物，伴有一些钙化。她接受了腹腔镜下肾部分切除术，未出现任何围手术期并发症。我们在肿瘤块中发现了乳头状肾细胞癌和嗜酸细胞瘤。
结论
在治疗嗜酸细胞瘤等良性肿瘤时，应考虑混合性恶性肿瘤的可能性。
