The main demographic group at risk is the pediatric population. Its seen mainly in children and adolescents from asia, central and south america and mexico. As well as other NK-cell lymphomas, EBV-positive lymphomas are associated with a deficient ctytotoxic immune response to EBV[4]. Adults are rarely affected.
