"Three major histopathologic categories:
- small noncleaved cell,
- large cell immunoblastic, plasmacytoid,
- and large noncleaved cell lymphomas.
Approx 90% of AIDS-associated NHLs express B-cell immunophenotypes including expression of monotypic surface Ig and/or the B cell-associated antigen CD20 (B1) and absence of T cell-associated antigens.
Approx 10% of AIDS-associated NHLs lack B- and T-cell-lineage restricted antigens. HIV appears not to be involved directly in the pathogenesis of AIDS-associated lymphoid neoplasia, because HIV DNA sequences could not be detected in AIDS-associated lymphoid neoplasms.
EBV, however, may be involved in the pathogenesis of up to one third of AIDS-associated B-NHLs"
