The Epstein-Barr virus, abbreviated EBV, is virus implicated in several types of cancer.
General
- Cases mononucleosis.
- Part of the herpes group of viruses.[1]
Note:
- The virus is Epstein... the tricuspid abnormality is Ebstein.
Associations
Cancer:[2]
- Classical Hodgkin lymphoma.
- Burkitt lymphoma.
- Nasopharyngeal carcinoma.
- B cell lymphomas -- in immunosuppressed individuals.
- Leiomyoma and leiomyosarcoma in the context of HIV.[3]
- Extranodal NK/T-cell lymphoma, nasal type.
- Epstein-Barr Virus-associated gastric carcinoma - EBV is thought to be associated with approximately 10% of gastric carcinomas.[4][5]
Other:
- Hemophagocytic syndrome.[6]
- Epstein-Barr virus-associated smooth muscle tumour - very uncommon, in immunoincompetent individuals.[7]
- EBV-associated colitis[8] - may mimic IBD.[9]

Microscopic
Features:
- Variable - see specific pathologies in Associations section.
- +/-Atypical lymphocytes.
- +/-Hemophagocytosis (uncommon).
Images:
IHC
- Mixed population of CD3 & CD20 -- in benign.
Molecular
- EBER +ve - in situ hybridization for RNA fragments in EBV.[10]
- EBER = Epstein-Barr virus (EBV)-encoded small RNAs.[11]
