Is gastric lymphoepithelioma-like carcinoma a special subtype of EBV-associated gastric carcinoma? New insight based on clinicopathological features and EBV genome polymorphisms.

Background Gastric lymphoepithelioma-like carcinoma (LELC) is a rare entity that is closely associated with Epstein–Barr virus (EBV). However, the EBV latency pattern and genome polymorphisms in gastric LELC have not been systematically explored.
