Abstract
The risk of developing malignancy is higher in patients with human immunodeficiency virus (HIV) infection than in non-HIV-infected patients. Several factors including immunosuppression, viral coinfection, and high-risk lifestyle choices lead to higher rates of cancer in the HIV-infected population. A subset of HIV-related malignancies are considered to be acquired immunodeficiency syndrome (AIDS)-defining malignancies, as their presence confirms the diagnosis of AIDS in an HIV-infected patient. The introduction of highly active antiretroviral therapy (HAART) has led to a significant drop in the rate of AIDS-defining malignancies, including Kaposi sarcoma, non-Hodgkin lymphoma, and invasive cervical carcinoma. However, non-AIDS-defining malignancies (eg, Hodgkin lymphoma, lung cancer, hepatocellular carcinoma, and head and neck cancers) now account for an increasing number of cancer cases diagnosed in HIV-infected patients. Although the number has decreased, AIDS-defining malignancies account for 15%-19% of all deaths in HIV-infected patients in the post-HAART era. Most HIV-related malignancies in HIV-infected patients manifest at an earlier age with a more aggressive course than that of non-HIV-related malignancies. Understanding common HIV-related malignancies and their specific imaging features is crucial for making an accurate and early diagnosis, which impacts management. Owing to the weakened immune system of HIV-infected patients, other entities such as various infections, particularly opportunistic infections, are prevalent in these patients. These processes can have confounding clinical and imaging manifestations that mimic malignancy. This article reviews the most common AIDS-defining and non-AIDS-defining malignancies, the role of imaging in their diagnosis, and the imaging mimics of malignancies in HIV-infected patients. ©RSNA, 2018.

Clinicopathological analysis of oral plasmablastic lymphoma: A systematic review. J Oral Pathol Med 2018; 47:915-922.

Abstract
BACKGROUND Plasmablastic lymphoma (PBL) is a high-grade lymphoma that often affects the oral cavity of HIV-positive patients; however, its prognostic determinants remain unknown. PURPOSE To integrate the available data on oral PBL to determine its clinicopathological features and to identify potential prognostic factors. METHODS An electronic systematic review was performed using multiple databases with a specific search strategy in February 2018. Inclusion criteria comprised cases diagnosed as PBL affecting the oral cavity and gnathic bones with sufficient data to confirm the diagnoses. RESULTS A total of 70 publications were included, representing 153 cases. Oral PBL predominantly affected HIV-positive males (76.4%). EBV was observed in 63.4% of the cases. The gingiva was the most involved site and the lesion usually presented as an asymptomatic swelling. Most cases were classified as stage I (21.6%), and chemotherapy alone was applied in 28.8% of the cases. There was a significant association between HIV and EBV infections, and cases affecting HIV-negative patients were more common in older individuals. Cumulative survival of the patients achieved 42.4% and 33.5% after 2 and 5 years, respectively. Although there were no statistically significant clinicopathological parameters in the univariate analysis, the multivariate Cox regression model demonstrated that EBV-positive status, presence of B-symptoms, and chemotherapy alone were independent prognostic determinants of a poor prognosis. CONCLUSION Oral PBL is an aggressive neoplasm with low survival rates, which is influenced by the presence of EBV, presence of B-symptoms, and with the use of chemotherapy only.

Reflection of ¹⁸F-FDG accumulation in the evaluation of the extent of periapical or periodontal inflammation. Oral Surg Oral Med Oral Pathol Oral Radiol 2012; 114:e62-9.

Abstract
OBJECTIVES To elucidate whether fluorine-18-labeled ((18)F) fluoro-2-deoxy-d-glucose (FDG) accumulation can reflect the extent of periodontal inflammation, periapical inflammation, or dental caries. STUDY DESIGN (18)F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) were retrospectively compared with the size of the bone resorption areas caused by periodontal inflammation, periapical inflammation, or dental caries on panoramic radiographs, CT, and magnetic resonance imaging (MRI) in 44 subjects. RESULTS A significant correlation was found between the size of the bone resorption area caused by periodontal (r = 0.595, P < .01) or periapical (r = 0.560, P < .01) inflammation and the highest standardized uptake value (SUVmax) of (18)F-FDG accumulation. A significant correlation was found between the periodontal (r = 0.622, P < .01) or periapical (r = 0.394, P < .01) inflammatory findings on MRI and the SUVmax of (18)F-FDG accumulation. The SUVmax of (18)F-FDG around most teeth with caries was under 1.5. CONCLUSIONS (18)F-FDG accumulation reflects the extent of dental inflammation, not dental caries.
