Answer

Congenital immunodeficiency states (eg, severe combined immunodeficiency disease [SCID], Wiskott-Aldrich syndrome), acquired immunodeficiency states (eg, AIDS), and induced immunodeficiency states (eg, immunosuppression) are associated with increased incidence of NHL and are characterized by a relatively high incidence of extranodal involvement, particularly of the GI tract, and with aggressive histology. Primary CNS lymphomas can be observed in about 6% of patients with AIDS.
