Leiomyosarcomas (LMS) arise from smooth muscle and represents only 6% of all sarcomas. LMS originating from major blood vessels, called vascular LMS, are detected mostly in the inferior vena cava. Arterial LMS are a rarity. We present a 43-year-old patient with a LMS arising from the left external iliac artery. The patient was referred to us with symptoms of left lower abdominal pain extending to the left limb and underwent a contrast computed tomography which suggested a suspicious mass near the left iliac vessels. She underwent laparoscopic excision of the tumour, whose histological examination revealed an LMS G2 arising from the external iliac artery. Immunohistochemically CD34, p53, Desmin, as well as smooth muscle actin, tested positive.
平滑肌肉瘤（LMS）起源于平滑肌，仅占所有肉瘤的6%。起源于大血管的LMS，称为血管LMS，大多在下腔静脉中被检测到。动脉LMS很罕见。我们报告一名43岁患者，其LMS起源于左髂外动脉。该患者因左下腹疼痛延伸至左下肢的症状被转诊至我们处，并接受了对比计算机断层扫描，结果显示左髂血管附近有一个可疑肿块。她接受了肿瘤的腹腔镜切除术，组织学检查显示为起源于髂外动脉的G2级LMS。免疫组化检测显示CD34、p53、结蛋白以及平滑肌肌动蛋白呈阳性。
