SUMMARY
The prevalence of HIV in the United States continues to rise as a result of the combined effects of a declining HIV death rate, and a sustained rate of new infections. Furthermore, HIV-infected patients on antiretroviral therapy can expect to live nearly as long as uninfected persons (within 5 years) providing ample time for individuals to develop AIDS-associated and non–AIDS-associated hematologic and oncologic conditions. HIV-infected individuals remain at increased risk of AIDS-defining malignancies such as Kaposi sarcoma, aggressive non-Hodgkin lymphoma, primary central nervous system lymphoma, and invasive cervical cancer and a number of non–AIDS-defining malignancies, including Hodgkin lymphoma, as well as anemia and thrombocytopenia. When individuals present with any of these hematologic or malignant illnesses it should be the standard of care to obtain HIV testing so as to provide optimal treatment to both the presenting illness and the HIV.

HIV, the virus that causes AIDS, is a lentivirus that originated as a simian immunodeficiency virus (SIV) in chimpanzees and entered the human population in the early 20th century in equatorial Africa.1,2 First isolated in 1983,3,4 HIV-1 actually comprises four distinct viruses (types M, N, O, and P) that represent four separate transmission events that occurred between chimpanzees and humans, likely the result of predation of monkeys by humans and mucosal or nonintact skin contact with infected fluids. Group M, the viral type responsible for the HIV-1 pandemic, was detected in a tissue sample from 1959 and probably entered the human population in or around Kinshasa, Democratic Republic of Congo (then ...
