Abstract
A case of gastric adenocarcinoma with sarcomatous differentiation in a 65-year-old male was investigated for possible association with the Epstein-Barr virus (EBV). The presence of EBV-DNA could be proven by the polymerase chain reaction (PCR), and EBERs signals were detected in tumour nuclei, strongly in sarcomatous areas and weakly elsewhere. Monoclonal EBV infection was evident in terms of a single band of lymphocyte determined membrane antigen demonstrated by the PCR method. Latent membrane protein 1 was strongly positive in cells of sarcomatous components but very weakly positive in carcinoma components. EBV-determined nuclear antigen-2 was absent in both. This case of adenocarcinoma suggests that EBV plays an important role in tumorigenesis, contributing in particular to sarcomatous differentiation.Entities:
