We present a 46-year-old female patient who underwent resection of a retroperitoneal tumor, which was found by medical check-up. The tumor which was elastic hard and had good mobility displaced the duodenum to her abdominal wall. Since her right ovarian vein adhered to the tumor, we removed the tumor with the ligated vein. Pathological findings showed the tumor consisted of spindle-shaped cells with pleomorphic nucleus and it presented the fascicular growth pattern. Additional immunostaining showed positive for HHF35, h-caldesmon. Because the leiomyosarcoma connected with the smooth muscle of the right ovarian vein, we considered the vascular smooth muscle was the origin of the tumor. It is 2 years after the operation, there has been no local recurrence or metastasis.
我们报告一例46岁女性患者，其通过体检发现腹膜后肿瘤并接受了切除术。肿瘤质地硬且有弹性，活动度良好，将十二指肠推移至腹壁。由于其右卵巢静脉与肿瘤粘连，我们在结扎静脉后切除了肿瘤。病理结果显示肿瘤由核多形性的梭形细胞组成，呈束状生长模式。进一步免疫组化显示HHF35、h-钙调蛋白呈阳性。由于平滑肌肉瘤与右卵巢静脉的平滑肌相连，我们认为肿瘤起源于血管平滑肌。术后2年，无局部复发或转移。
