Lymph node Fine Needle Cytology, Epstein Barr virus infection and Hodgkin Lymphoma.
Epstein-Barr virus (EBV) is a double-stranded DNA virus of the herpes family; it is one of the most common human viruses and it is associated with a wide spectrum of benign and malignant conditions. EBV is related to the development of several neoplasms, globally 1% of tumours, including lymphoproliferative, epithelial and mesenchymal neoplasm. Lymphoproliferative disorders include Hodgkin lymphoma (HL) and B and T cell non-Hodgkin lymphomas. HL is one of the most common lymphoma in the developed world, affecting both young people and adults. HL pathogenesis is complex and includes various and partially unknown mechanisms. EBV has been detected in some HL neoplastic cells and expresses genes with a potential oncogenic function, therefore many studies suggest that viral infections have a causative role in neoplastic transformation. Fine Needle Cytology (FNC) is extensively used in the first diagnosis of any lymph-nodal enlargement, including reactive lymphadenopathies and lymphoproliferative processes; therefore cytopathologists are likely to encounter EBV-associated malignancies in cytology samples, mainly HL, which is one of the most common lymphoma. This study focuses on the cytological features and ancillary studies required to diagnose EBV-related HL.
