Intrahepatic Lymphoepithelioma-Like Cholangiocarcinoma Not Associated with Epstein-Barr Virus: A Case Report
Lymphoepithelioma-like cholangiocarcinomas are rare tumors and most of them are related with Epstein-Barr virus (EBV) infection. Here, a case of a patient with lymphoepithelioma-like cholangiocarcinoma not associated with EBV infection is presented. In a 79-year-old man with hepatitis B virus-associated cirrhosis, a liver mass was detected on abdominal CT. Macroscopically, the resected tumor wa...
متن کاملPresence of Epstein-Barr virus in lymphoepithelioma-like carcinoma of the middle ear.
AIM To examine the association of Epstein-Barr virus (EBV) with carcinoma of the ear. METHODS Five non-keratinising squamous cell carcinomas and two undifferentiated carcinomas of the ear were examined. In situ hybridisation was used to localised EBV-encoded RNAs (EBER). Immunohistochemical methods to detect LMP-1 and EBNA2 were performed in the EBER positive cases. RESULTS Two cases were E...
متن کاملEpstein-Barr Virus-Associated Lymphoepithelioma-Like Gastric Carcinoma Presenting as a Submucosal Mass: CT Findings with Pathologic Correlation
A lymphoepithelioma-like carcinoma, characterized by a carcinoma with heavy lymphocyte infiltration, is one of the histological patterns observed in patients with Epstein-Barr virus (EBV)-associated gastric carcinoma. Less than half of invasive carcinomas with lymphoepithelioma-like histology can grow to make a submucosal mass. These tumors generally have a better prognosis than conventional ad...
متن کاملEpstein-Barr Virus (EBV)-associated Gastric Carcinoma
The ubiquitous Epstein-Barr virus (EBV) is associated with several human tumors, which include lymphoid and epithelial malignancies. It is known that EBV persistently infects the memory B cell pool of healthy individuals by activating growth and survival signaling pathways that can contribute to B cell lymphomagenesis. Although the monoclonal proliferation of EBV-infected cells can be observed ...
متن کاملThe oncogenic role of Epstein–Barr virus‐encoded microRNAs in Epstein–Barr virus‐associated gastric carcinoma
Epstein-Barr virus (EBV) infection is detected in various epithelial malignancies, such as nasopharyngeal carcinoma (NPC) and gastric cancer (GC). EBV comprises some unique molecular features and encodes viral genes and microRNAs (miRNAs) by its own DNA sequence. EBV genes are required to maintain latency and contribute to oncogenic property. miRNAs encoded by EBV have been shown to contribute ...
