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 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 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 کاملRectal tonsil associated with Epstein-Barr virus.
Reactive polypoid proliferation of lymphoid tissue has been described along the gastrointestinal tract [1]. Endoscopically, when a non-lymphomatous lymphoid reaction resembling tonsillar tissue is present in the rectum, the polyp is named as “rectal tonsil”. Few cases have been reported in the literature [1,2], and the etiology of this rare condition is unknown [3–5]. Here we describe the case ...
متن کاملEpstein–Barr virus-associated lymphomas
Epstein-Barr virus (EBV), originally discovered through its association with Burkitt lymphoma, is now aetiologically linked to a remarkably wide range of lymphoproliferative lesions and malignant lymphomas of B-, T- and NK-cell origin. Some occur as rare accidents of virus persistence in the B lymphoid system, while others arise as a result of viral entry into unnatural target cells. The early ...
