Extensive intra-abdominal-retroperitoneal fat necrosis is rare, especially its occurrence in cases of renal cell carcinoma (RCC). We report a patient who presented with a palpable left lower abdominal mass. The RCC was an incidental radiographic finding. The fat necrosis exhibited properties similar to a liposarcoma at laparotomy and on histologic examination of frozen tissue sections. Debulking surgery with left hemicolectomy, transverse colostomy and a midrectal Hartmann pouch was performed. In subsequent surgery, radical right nephrectomy and closure of the colostomy were performed. There were no discernible factors predisposing this patient to fat necrosis. To our knowledge, such extensive intra-abdominal-retroperitoneal fat necrosis is extremely rare. A literature search failed to find a similar case of intra-abdominal or retroperitoneal fat necrosis in association with RCC.
广泛的腹腔内-腹膜后脂肪坏死很少见，尤其是在肾细胞癌（RCC）病例中发生。我们报告一名患者，其左下腹部可触及肿块。肾细胞癌是偶然的影像学发现。在剖腹手术和冰冻组织切片的组织学检查中，脂肪坏死表现出与脂肪肉瘤相似的特征。进行了包括左半结肠切除术、横结肠造口术和直肠中段Hartmann袋的减瘤手术。在随后的手术中，进行了根治性右肾切除术和结肠造口闭合术。没有发现导致该患者发生脂肪坏死的明显因素。据我们所知，如此广泛的腹腔内-腹膜后脂肪坏死极为罕见。文献检索未发现与肾细胞癌相关的类似腹腔内或腹膜后脂肪坏死病例。
