We retrospectively analyzed 45 cases of HIV-associated Hodgkin lymphoma (HIV-HL). HIV-HL generally is a disease of young white men (mean age, 40.1 years) who acquired HIV infection by homosexual or bisexual behavior (68%), intravenous drug use (24%), and/or blood transfusion (8%). The mean interval between the diagnosis of HIV and HIV-HL was 5.2 years. Morphologic classification of nodal biopsy specimens (2001 World Health Organization criteria) included 15 mixed cellularity Hodgkin lymphomas (MCHLs), 14 nodular sclerosis Hodgkin lymphomas (NSHLs), 9 lymphocyte depleted Hodgkin lymphomas (LDHLs), and 7 classic Hodgkin lymphomas, type not further categorized. The Hodgkin-Reed-Sternberg (HRS) cells expressed positive immunoreactivity with fascin (30130 [100%]), CD30 (35137 [95%]), CD15 (32136 [89%]), bcl-X-L (25131 [81 %]), bcl-2 (15129 [52%]), CD20 (4134 [12%]), bcl-6 (3128 [11 %]), and Epstein-Barr virus latent membrane protein-1 (32/33 [97%]) and were nonreactive for CD138/syndecan-1. CD4 and CD8 immunostaining showed an inverted CD4/CD8 ratio (<1/20) in all cases. At diagnosis, most patients (n = 27) had high-stage disease (IVE) associated with an aggressive course (16% 5-year survival). LDHL behaved more aggressively than MCHL and NSHL (15% vs 40%, 5-year survival, respectively), as did disease with a sarcomatoid pattern (11% 5-year survival). Chemotherapy and radiotherapy proved efficacious in a minority of these patients.
