Abstract：
Myolipomas are rare tumors that are often difficult to differentiate from liposarcoma. Herein, we report a case of resected giant myolipoma preoperatively diagnosed as liposarcoma. A 63-year-old woman was suspected of having a large retroperitoneal liposarcoma on October 202X. The patient was referred to our department for tumor resection and a histological diagnosis. After consultation with the urology, obstetric and gynecology, and vascular surgery departments, tumor resection was planned, including the potential resection of other organs. Intraoperative findings revealed a large, elastic, soft tumor with a smooth surface and a capsule occupying the entire abdominal cavity. The tumor was adherent to the stomach, left colon, and uterine adnexa, and no invasion was observed. The tumor was completely resected, and organ resection was not necessary. The tumor was 40 cm in diameter and 4.0 kg in weight. Pathological examination and immunostaining confirmed a diagnosis of myolipoma. The patient\'s postoperative course was uneventful, and she was discharged on postoperative day 10 with no complications. Twelve months after surgery, the patient was doing well. To the best of our knowledge, we report a complete resection of the largest retroperitoneal myolipoma reported to date. Physicians should consider surgery, even for suspected large sarcomas that may be difficult to resect completely.
摘要：
肌脂瘤是罕见的肿瘤，通常难以与脂肪肉瘤区分。在这里，我们报告一例切除的巨大肌脂瘤术前诊断为脂肪肉瘤。一名63岁的妇女在202X年10月被怀疑患有大型腹膜后脂肪肉瘤。患者被转诊至我们部门进行肿瘤切除和组织学诊断。在与泌尿科协商后，妇产科,和血管外科，计划切除肿瘤，包括其他器官的潜在切除。术中发现了一个大的，弹性，具有光滑表面和占据整个腹腔的囊膜的软肿瘤。肿瘤附着在胃上，左结肠,和子宫附件，没有观察到入侵。肿瘤完全切除,器官切除是不必要的。肿瘤直径为40cm,重量为4.0kg。病理检查和免疫染色证实了肌脂肪瘤的诊断。病人的术后过程是顺利的，术后第10天出院，无并发症。手术后12个月,病人做得很好。据我们所知,我们报道了迄今为止报道的最大的腹膜后肌脂肪瘤的完整切除术.医生应该考虑手术，甚至对于可能难以完全切除的疑似大型肉瘤。
