目的分析肝脏血管周上皮样细胞瘤的临床特点。方法2007年10月首都医科大学附属北京友谊医院普外科诊治1例肝脏血管周上皮样细胞瘤,对其临床、影像、病理学特点进行分析及相关文献复习。结果肝脏血管周上皮样细胞瘤无临床症状,无特征性影像学表现,术前难于确诊。组织学上由单一上皮样细胞构成,不含血管及脂肪成分,免疫组化呈特征性黑色素生成(HMB-45)阳性。目前文献报道肝脏血管周上皮样细胞瘤发生在肝脏者尚不足10例。结论肝脏血管周上皮样细胞瘤是一种非常罕见的间叶组织来源肿瘤。主要依靠病理进行诊断。肝脏血管周上皮样细胞瘤生物学行为不确定,建议术后长期随访。
Objective To analyze the clinical features of hepatic pericytes. Methods One case of peritumoral neoplasia of the liver was diagnosed and treated in Department of General Surgery, Beijing Friendship Hospital, Capital Medical University in October 2007, and its clinical, imaging and pathological features were analyzed and related literatures were reviewed. Results Perivascular epidermoid tumor of the liver had no clinical symptoms and no characteristic imaging findings, which was difficult to diagnose before operation. Histologically composed of a single epithelial-like cells, free of vascular and fat components, characterized by immunohistochemistry melanin (HMB-45) positive. It is reported in the literature that hepatic pericytes is still less than 10 in the liver. Conclusion Peripheral blood cell tumor of the liver is a very rare tumor of mesenchymal origin. Mainly rely on the pathological diagnosis. The biological behavior of perivascular epithelioid tumor of the liver is indefinite. It is suggested that long-term postoperative follow-up should be followed.
