摘要
肝血管平滑肌脂肪瘤(HAML)是一种少见的肝脏良性肿瘤,临床表现无特殊,影像学表现多样,术前诊断困难,容易误诊;病理诊断需依赖标本免疫组织化学染色,肿瘤平滑肌样细胞表达HMB-45阳性。综合影像学检查有助于该肿瘤特征的显示和术前正确诊断。肿瘤平滑肌样细胞表达HMB-45阳性,是诊断HAML的可靠依据。手术切除是HAML的有效治疗手段。
Hepatic angiomyolipoma（HAML）is a rare hepatic benign tumor with no special clinical manifestations but various imaging appearances.The preoperative diagnosis of HAML is difficult and easily misdiagnosed.Definite pathological diagnosis should rely on the imm-unohistochemistry：the expression of HMB-45 in smooth muscle-like cells of the tumor is positive.Combining with imaging appearances contributes to the display of the tumor characteristics and the correct preoperative diagnosis.Smooth muscle-like cells of the tumor express HMB-45 positively,which is the reliable basis of diagnosing HAML.Surgical resection is an effective treatment for HAML.
