Abstract

We examined eight (6 parotid, 1 caecum, 1 lymph node) non Hodgkin's Lymphomas (NHL) complicating primary Sjögren's syndrome (SS), four parotid NHL, in patients without SS, and three salivary gland biopsies from SS patients and no NHL, for Epstein Barr virus (EBV), using immunohistochemistry for late membrane protein, in situ hybridisation (ISH) for EBER, and PCR for EBV DNA. Late membrane protein was not detected. In NHL's complicating SS, EBERs were detected in two parotid lymphomas by ISH. EBV DNA was detected in three SS parotid NHL. Cecal and lymph node SS NHL were negative for EBER and EBV DNA. EBV DNA was detected in two non SS NHLs, one expressed EBER. Despite positive EBV DNA results by PCR in three samples expression of EBER was noted in only one by ISH. This was a high grade NHL complicating SS. There was no evidence of EBV in low grade NHLs complicating SS.
