title: Hodgkin's lymphoma: immunohistochemical features and its association with EBV LMP-1. Experience from a South Indian hospital.
abstract: OBJECTIVE
  Immunohistochemistry (IHC) is known to aid in the diagnosis of Hodgkin's lymphoma (HL). We studied HL using an antibody panel for Reed-Sternberg cells (RSCs) to find which antibody would be most useful for identification of RSCs. We also studied the association of Epstein-Barr virus (EBV) latent membrane protein-1 (LMP-1) with HL in South India.
  
  
  METHODS
  Lymph node biopsies of 100 cases of untreated HL were included in this study. Antibodies against CD15, CD30, CD3, CD20 (L26), CD45 (LCA), EMA and EBV LMP-1 were used for paraffin section IHC.
  
  
  RESULTS
  Of the 100 cases of HL, the RSCs stained with CD30 (93%), CD15 (67%), CD20 (17%) and CD3 (2%). EBV LMP-1 was positive in 82 (82%) cases, most often in the nodular sclerosis subtype, 43 (86%) cases.
  
  
  CONCLUSIONS
  (1) Of the panel of antibodies, CD30 was the most useful in identifying RSCs in classical HL. (2) EBV LMP-1 was demonstrated in 82% of all cases of HL and in 96% of childhood cases.
