| 目的 探讨超声在肢体上皮样肉瘤诊断中的临床价值。方法 收集我院经手术病理证实为肢体上皮样肉瘤患者43例资料，分析其术前超声图像特征，并随访其短期复发情况。结果 43例肢体上皮样肉瘤超声均明确提示病变位置，定位准确率100%；声像图表现均呈团块状低回声，均无包膜，平均最大径（5.73±4.99）cm，为以实性为主（81.4%），边界不清晰（55.8%），形态不规则（88.4%），内部回声不均匀（95.3%），多为单发（72.1%），血流分级Ⅲ级（53.5%）。超声明确提示软组织肿物42例，另有1例患者肿物感不明显，超声提示为神经病变，瘢痕粘连。术后随访3个月至8年，出现复发并再次手术者22例，超声均直接提示复发，声像图均表现为回声不均匀的实性低回声，边界不清晰（15/22），形态不规则（16/22），Alder血流分级均为Ⅰ级。结论 肢体上皮样肉瘤声像图表现多为单发不规则团块状实性低回声肿物，无包膜，边界不清晰，内部回声不均匀，血流较丰富。超声不仅可在术前明确病变范围及其周围组织受累情况，术后亦可动态随访，具有重要的临床价值。 |

| Abstract: |
| Objective To explore the clinical value of ultrasound in the diagnosis of epithelioid sarcoma of limb. Methods 43 patients with epithelioid sarcoma confirmed by surgery and pathology were collected.The characteristics of ultrasound images were compared with the surgical results. And follow up on their short-term recurrence status. Results The ultrasonography of 43 cases of limb epithelioid sarcoma clearly indicated the location of the lesion, and the localization accuracy was 100%. The ultrasonographic manifestations were all lumpy hypoechoic, all without envelope, with an average maximum diameter of (5.73±4.99) cm, mainly solid (81.4%), unclear boundary (55.8%), irregular shape (88.4%), uneven internal echo (95.3%), mostly single lesions(72.1%), and blood flow grading grade III (53.5%). Ultrasound clearly indicated soft tissue mass in 42 cases, and the tumor sensation was not obvious in another case. Ultrasound indicated neuropathy and cicatricial adhesion. After 3 months to 8 years of postoperative follow-up, 22 patients with recurrence and re-operation were directly indicated by ultrasound, and ultrasonography showed uneven solid hypoecho, unclear boundary (15/22), irregular shape (16/22), and Alder blood flow grading was grade I. Conclusion Ultrasound examination of limb epithelioid sarcoma often presents as a single, irregular, solid hypoechoic mass with no capsule, unclear boundaries, uneven internal echoes, and abundant blood flow. Ultrasound can not only clarify the extent of the lesion and its surrounding tissue involvement before surgery, but also provide dynamic follow-up after surgery, which has important clinical value. |
