As a non-Hodgkin lymphoma (NHL),<unk>  makes up 1-5% of cases, and it is more common in males than females with a 3-4 to 1 ratio. The endemic variant mainly impacts areas with an increased prevalence of malaria and EBV in Africa and Papua New Guinea. For children less than 18 years of age from equatorial Africa, the annual incidence of<unk>  is 4-5/100,000. Additionally, in equatorial Africa, 50% of tumors that are diagnosed during childhood as well as 90% of lymphoma cases can be attributed to<unk> . The peak incidence for endemic<unk>  is from ages 4 to 7 with an average age of 6 years. The sporadic variant with an annual incidence 2-3/million is more commonly found in North America and Europe comprising 1-2% of adult lymphomas and 30-40% of NHL cases. This variant is 3.5 times more commonly found in males compared to females and it is more frequent in younger individuals. The sporadic variant has a peak incidence at 11 years of age in children, and diagnosis typically occurs from 3–12 years of age on average. For adults, 45 years was the median age that the sporadic<unk>  was diagnosed. The immunodeficiency-associated variant predominantly impacts the HIV-infected population. For those in the United States and with AIDS, the incidence of this variant was found to be 22/100,000 person-years. There is also an increased risk of developing this variant of<unk>  for individuals that have received an organ transplant after 4–5 years. EBV infection is associated with<unk> . EBV is found in virtually all instances of endemic<unk> . The sporadic variant of<unk>  is associated with EBV in only 10-20% of cases. Approximately 30% of immunodeficiency-associated<unk>  cases were associated with EBV.
