Acquired immune deficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), is now a well-established pandemic. HIV/AIDS has direct and indirect effects on virtually all anatomical body sites. Progressive immune deficiency leaves individuals susceptible to opportunistic infections and several AIDS-defining cancers (non-Hodgkin lymphoma, Kaposi sarcoma, and cervical cancer). As HIV-infected individuals are living longer due to antiretroviral therapy and prophylaxis, non-AIDS-defining cancers (e.g., Hodgkin lymphoma, lung carcinoma, and liver cancer) are becoming increasingly recognized. Drug-related changes such as skin rashes and Kaposi sarcoma flare in the setting of treated HIV frequently complicate the picture.

We invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to better understand, recognize, and diagnose AIDS-related pathologies. We are particularly interested in HIV/AIDS articles that describe emerging pathologic entities, discuss controversial issues, present novel disease pathogenesis, report diagnostic pearls and pitfalls, and that relay shared expertise in this field from around the world. Potential topics include, but are not limited to:

• Advances in HIV virology, pathogenesis, and diagnosis
• Updates on HIV-related host immunity
• Direct and indirect pathologic effects of HIV/AIDS
• HIV-associated opportunistic and other coinfections
• Developments in AIDS defining cancers
• Recent advances in non-AIDS malignancies
• Current topics of interest in nonneoplastic AIDS-related disorders
• Drug-related pathology in AIDS patients
• Approach to biopsies (e.g., skin, lung) in HIV patients

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/pri/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
