"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"
