Primary Leiomyosarcoma of Liver:A Case Report and Review of Literature

目的 :探讨肝脏原发性平滑肌肉瘤的诊断和鉴别诊断。方法 :应用超声引导下自动活检技术、组织病理学、免疫组织化学观察 1例肝脏原发性平滑肌肉瘤并复习相关文献。结果 :组织学观察瘤细胞呈梭形 ,可见核分裂 ,免疫组织化学结果 :CEA(- )、EMA(- )、vimentin(+)、Myosin(Smooth Muscle) (+)。结论 :肝脏原发性平滑肌肉瘤是一种罕见的恶性间叶肿瘤 ,其诊断主要依靠免疫组织化学。

Objective:To explore the diagnosis and differential diagnosis of primary leiomyosarcoma of liver.Methods:One case of primary leiomyosarcoma of liver was studied with ultrasound-guided super core needle biopsy, histopathologcal and immunohistochemical stains.Results:Microscopically, the tumor cells were positive for vimentin、Myosin(Smooth Muscle), negative for CEA、EMA.Conclusion:Primary leiomyosarcoma of liver was a rarely neoplasm,and its diagonosis should mainly rely on immunohistochemical findings.
