Abstract］ objective to study the pathological features and histopathological type and differential diagnosis of hepatic focal nodular hyperplasia.methods the clinicopathological characteristics of 40 cases of fnh were studied.all were evaluted by use of paraffin embedded sections and he staining before light microcope observation.results there were 28 females and 12 males fnh patients whose age were from 16 to 62 years（median 41.3）,all alpha-fetoprotein was negative and had no hepatitis history.25 cases were classic type showed characteristic central stellate fibrotic scar,composed of fibrous connestive tissue and tortuous blood vessels.8 cases were telangiectic type,the left were mixed type and adenomatoid type.conclusion fnh is a reactive proliferation of hepatic cells to local blood vessel anomalies,it is not realy a tumor.its differential diagnosis includes hepatic adenomatous hyperplasia nodule,hepatic anaplasia nodular hyperplasia,fibrolamellar hepatocellular carcinoma and hepatocellular adenoma.

目的 探讨肝局灶性结节性增生的病理形态特点、组织分型及鉴别诊断。方法分析40例肝局灶性结节性增生的临床资料，并采用石蜡包埋he染色光镜下观察其组织学特点。结果 40例肝局灶性结节性增生患者中，女28例，男12例，年龄18~62岁，平均年龄41.3岁，所有病例术前均无肝炎病史，甲胎蛋白阴性，组织学上25例为经典型，有特征性的中央纤维瘢痕，由纤维结缔组织及扭曲血管组成。8例为毛细血管扩张型，其余为混合型及腺瘤样增生型。结论肝结节性增生是一种肝细胞对局部血管的异常反应性增生，并非真性肿瘤，主要与肝腺瘤样增生性结节、肝间变性结节状增生、肝纤维板层癌及肝细胞腺瘤鉴别。
