BACKGROUND
Liposarcoma is one of the most common soft tissue sarcomas found in adults. It has a predilection for retroperitoneal space. Renal cell carcinoma is the most common tumor of the kidney.
CASE PRESENTATION
Concurrent retroperitoneal liposarcoma and renal cell carcinoma were found in a 34-year-old Japanese man. The renal tumor was first detected by ultrasonography, it was confirmed by computed tomography, which also identified a presumptive retroperitoneal liposarcoma, and the tumors were further assessed with magnetic resonance imaging. The patient was treated by surgical resection of retroperitoneal liposarcoma and left nephrectomy and has been disease-free for 10 years.
CONCLUSIONS
The concomitant occurrence of a renal tumor and a primary primary liposarcoma is rare. The major factors promoting a good prognosis in this case were the favorable histology and the small size of the tumors.
背景
脂肪肉瘤是成人中最常见的软组织肉瘤之一。它好发于腹膜后间隙。肾细胞癌是肾脏最常见的肿瘤。
病例报告
一名34岁日本男性同时患有腹膜后脂肪肉瘤和肾细胞癌。肾肿瘤最初通过超声检查发现，随后经计算机断层扫描确诊，该检查还发现了疑似腹膜后脂肪肉瘤，之后通过磁共振成像对肿瘤进行了进一步评估。患者接受了腹膜后脂肪肉瘤手术切除及左肾切除术，目前已无病生存10年。
结论
肾肿瘤与原发性脂肪肉瘤同时发生的情况较为罕见。该病例预后良好的主要因素是组织学类型良好以及肿瘤体积较小。
