异位肝组织临床病理特点及文献复习

【摘要】 目的探讨异位肝组织临床病理特点。方法对1例胆囊异位肝组织进行临床病理及免疫组化观察,并复习相关文献。结果异位肝组织位于胆囊颈浆膜面,表面被膜完整,镜下具有肝小叶及汇管区结构,肝细胞水样变性、灶性脂肪变及汇管区淋巴细胞浸润。异位肝组织免疫组化显示HBsAg和HBcAg均阳性,AFP阴性。结论异位肝组织非常少见,异位肝可发生肝脏常见的相应病变甚至癌变。胆囊异位肝最多见但却很少发生癌变。更多还原

【Abstract】 Objective To investigate the clinicopathological feature of ectopic liver.Methods One case of ectopic liver of gallbladder was analyzed from the clinicopathological feature and immunostaining with antibodies HBsAg,HBcAg and AFP,also and review of the literature.Results The ectopic liver which was encapsulated by fibrosa was attached to the serosal surface of gallbladder neck.Microscopic examination showed the nodule was composed of portal triads and lobules.Additonally,hydropic and fatty degeneration in some hepatic cells and lymphocytic infiltrates in portal triads of the ectopic live were seen.Tumors were positive for HBsAg and HBcAb,but negative for AFP immunohistochemically.Conclusion Ectopic liver is rare and is subject to the same lesion as the mother liver,even ectopic hepatocellular carcinoma.The gallbladder is the commonest origin site of ectopic liver,but in which ectopic hepatocellular carcinoma is rare.更多还原
