Definition / General
  • Clonal proliferation of EBV positive lymphocytes in patients > 50 years, with no known immunodeficiency state or prior lymphoma, and excluding patients with well defined EBV+ disorders such as primary effusion lymphoma
Clinical Features
  • Extranodal (skin, lung, tonsil and GI tract) involvement common
  • Aggressive disease, with median survival of 2 years (Clin Cancer Res 2007;13:5124)
  • Poorer prognosis if age > 70 years or B symptoms
Micro Description
  • Effaced lymph node architecture due to large cells (immunoblasts / centroblasts) with admixed reactive small lymphocytes, plasma cells and histiocytes
Positive Stains
Negative Stains
Molecular / Cytogenetics Description
  • Clonal population by molecular techniques, in contrast to infectious mononucleosis
