Abstract:
Hepatic lymphoepithelioma-like carcinoma(LELC)is an extremely rare malignant tumor characterized by undifferentiated malignant epithelial cells and significant lymphatic infiltration.Hepatic LELC mainly includes lymphoepithelioma-like hepatocellular carcinoma(LEL-HCC)and lymphoepithelioma-like intrahepatic cholangiocarcinoma(LEL-CC).Epstein-Barr virus(EBV)infection is considered as an important factor in LELC carcinogenesis.Since 2005,Xiangya Hospital of Central South University has treated a total of 3 patients with EBV-associated LEL-CC,which all showed liver masses by CT scans.After surgical resection,the EBV encoded RNA(EBER)and CK19 expression in all 3 patients were positive,and pathological examination confirmed EBV-associated LEL-CC.Two patients had a good postoperative prognosis,while 1 patient received relevant immunotherapy and chemotherapy after surgery.Based on the analysis of existing literature,the author believes that hepatic LELC can be included in the classification of liver tumors,which will provide new ideas for the accurate diagnosis and treatment of hepatic LELC.
