The treatment and outcome of human immunodeficiency virus (HIV) infection altered dramatically in the mid-1990s with the introduction of highly active antiretroviral therapy (HAART). Highly active antiretroviral therapy, where available, has led to a dramatic decline in mortality from HIV and a decrease in the incidence of opportunistic infections and Kaposi sarcoma. This article addresses the effects that HAART has had on acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin's lymphoma (NHL). Metaanalysis of numerous cohort studies confirmed that the incidence of AIDS-related NHL has decreased since the advent of HAART. This decline is most marked for primary cerebral lymphomas and systemic immunoblastic lymphoma but has not been demonstrated for Burkitt lymphoma. In addition to genetic predisposing factors, age, nadir CD4 cell count, and lack of HAART therapy predict the development of NHL. The clinical presentation of AIDS-related NHL has not changed, but several institutions have reported an improvement in survival since the introduction of HAART. Moreover, HAART has been combined safely with systemic chemotherapy in the management of NHL, and this approach results in a more modest decrease in immune function than when chemotherapy is administered alone. This has led to a more aggressive approach to the management of AIDS-related NHL and response rates and overall survival durations that are approaching those seen in stage-matched high-grade lymphomas in the immunocompetent population.

Plasmablastic lymphoma is a rare subcategory of non-Hodgkin lymphoma frequently associated with human immunodeficiency virus. It is a large B-cell lymphoma that has a predilection for the oral cavity. Clinically, plasmablastic lymphoma may mislead to a diagnosis of Kaposi's sarcoma. When infected, plasmablastic lymphoma may mimic an odontogenic cellulitis. Epstein-Barr virus and human herpesvirus 8 are very often associated. Awareness of this entity can prevent misdiagnosis with nonlymphoid malignancies, notably Kaposi's sarcoma, because this lesion does not express the conventional B-cell markers. Unfortunately, as for other high-grade lymphomas in patients with acquired immunodeficiency syndrome (AIDS), the prognosis is poor. The case of a heterosexual 42-year-old man referred for a right hemifacial neoplasm is reported.
