The acquired immunodeficiency syndrome (AIDS) results in an extraordinary increase in the risk of two malignancies: Kaposi's sarcoma (KS; relative risk [RR], >10,000) and B-cell non-Hodgkin's lymphoma (NHL; RR, >100). KS appears to result from uncontrolled expression of latency genes of human herpes virus-8 (HHV-8). KS is exquisitely sensitive to immune deficiency, and its incidence has declined during the late 1990s with the advent of highly active antiretroviral therapy (HAART) against human immunodeficiency virus (HIV). The risk of NHL is highest with high-grade histologies, and the incidence has declined only slightly with HAART. The risk of KS and NHL is decreased for people with the CCRS delta32 polymorphism, and NHL risk is increased with the SDFI-3'A polymorphism. Children with AIDS have a similar pattern of risk, but also have a high risk of leiomyosarcoma (RR, approximately 10,000). AIDS-related immune deficiency also increases the risk of Hodgkin's disease (RR, 8), probably multiple myeloma (RR, 5), and possibly other tumors in adults. Although the occurrence of cervical cancer (RR, 3) and anal cancer (RR, 30) is excessive among persons with AIDS, most or all of this excess results from sexually acquired human papillomavirus (HPV) infection and not from immune deficiency. Future efforts need to focus on understanding how the immune perturbation of AIDS results in a limited spectrum of tumors and most urgently on controlling the underlying HIV epidemic.

Herpes viruses have been implicated in the etiology of Hodgkin's disease (HD). We studied the prevalence of human cytomegalovirus (CMV), human herpes viruses type-6 (HHV-6), type-7 (HHV-7) and type 8 (HHV-8) DNA in up to 88 Hodgkin's disease biopsies in comparison to Epstein-Barr virus (EBV) DNA by polymerase chain reaction (PCR). Non-Hodgkin lymphomas (NHL) and reactive lesions served as controls. CMV and HHV-6 were found in 8/86 (9%) and 11/88 (13%) HD cases, respectively, by nested primer PCR. Except for three cases harbouring HHV-6 type-B, only HHV-6 type-A was detected in HD. HHV-7 was observed by nested PCR in 33/88 (38%) HD cases and was already detectable in 15/88 (17%) HD cases by a single-round PCR indicating elevated virus copy numbers. Seven of these cases showed co-infection with HHV-6, and 11 cases were found to contain EBV DNA. 7/8 CMV-positive HD cases also harboured EBV DNA. HHV-8 DNA was not detected by single round or nested PCR in any HD case investigated. Thus, CMV, HHV-6, and HHV-7 were present in small proportions of HD cases, with frequent co-infection of HHV-6 and HHV-7, and frequent association with EBV. In contrast to EBV, beta-herpes viruses are therefore unlikely to have a role in the aetiology of HD. Rather, the presence of these viruses seems to reflect impaired immunological surveillance.

We describe a patient with a clinical disorder that resembled vasculitic neuropathy in which peripheral nerves were successively affected over several months, but without systemic involvement. An initial muscle biopsy near the involved nerves showed signs of nonspecific inflammation around the muscle and nerve fibers. Immunosuppressive treatment resulted in a dramatic reduction in pain, but relapses of the disease eventually occurred, and the patient died 22 months after onset of the first symptoms. Pathologically, a malignant non-Hodgkin's B-cell lymphoma, restricted to the intra- and extradural peripheral nervous system, was found. The demonstration by Southern blotting of immunoglobulin heavy chain gene rearrangement confirmed the monoclonal nature of the lymphomatous cells. In situ hybridization tests for Epstein-Barr and herpes virus subtypes were negative. Our case underlines i) how difficult diagnosis can be despite extensive investigations, ii) the usefulness of immunosuppressive treatment in the early stage of the disease, iii) the importance of immunostaining and genome analysis for distinguishing between different types of human neurolymphomatosis, and iv) the fact that the initial inflammatory process in the muscle biopsy may be interpreted either as a paraneoplastic effect of the lymphoma or as a viral inflammatory neuromyopathy that triggers the development of the malignant lymphoma.

Primary effusion lymphomas represent an unusual subset of AIDS-related non-Hodgkin's lymphomas. They are associated with herpes virus 8 and Epstein-Barr virus and characterized by predominant involvement of the serous body cavities (pleura, pericardium, peritoneum) as lymphomatous effusion without any identifiable tumour mass. We report herein CT findings in two patients with primary effusion lymphoma emphasizing the possible neoplastic nature of a pleural effusion in a patient with AIDS.

The study of AIDS and cancer has resulted in an important convergence of clinical-epidemiological investigations, molecular research and virological studies. This shared effort has led to significant discoveries in the field of human carcinogenesis. In a relatively short time, several topics have been clarified, namely: (1) the spectrum of AIDS-related tumours has been identified; (2) the role of HIV in lymphomagenesis and in the development of Kaposi's sarcoma (KS) has been defined; (3) AIDS-related cancers have allowed the discovery and extensive biological characterisation of the novel virus human herpes virus 8 (HHV8), also called KS-associated herpesvirus; and (4) genetic, molecular, and phenotypic studies of AIDS-related lymphomas have contributed to the formulation of a pathogenetic and histogenetic model of B-cell non-Hodgkin's lymphomas (NHL).

Epstein-Barr virus (EBV), a human herpes virus, is associated with a variety of malignancies. In vitro, it is able to transform B cells, which will grow as lymphoblastoid cell lines in the absence of T cells. Patients with a variety of immunodeficiency diseases are subject to the development of B-cell lymphomas that express viral antigens on their cell surface. Development of EBV-associated B-cell lymphomas is seen in solid organ transplant and bone marrow transplant recipients receiving immunosuppressive therapy. Transfer of mature T cells from EBV-immune marrow donors has been demonstrated to be effective in controlling these EBV-associated B-cell tumors. Recently the demonstration that EBV transcripts are found in other lymphomas (including Hodgkin disease cells) has led to the suggestion that transfer of EBV-specific T cells may also be effective in managing these tumors. Current research involves optimizing methods to expand cells that recognize the EBV antigens expressed in the lymphoma cells.

Two type of human herpes viruses, type 4(Epstein Barr virus, EBV) and type 8(HHV8) are known to cause malignancies. Among those, EBV is the very most popular human oncovirus. It can cause malignant lymphomas of various subtypes including Burkitt's lymphoma, opportunistic lymphomas, pyothorax-associated lymphoma, nasal T/NK cell lymphoma, Hodgkin's disease and a part of diffuse large cell lymphomas. HHV8 is a new member of human oncovirus associating with primary effusion lymphoma, a part of solid lymphoma taking diffuse large or anaplastic large cell morphology, and the Castleman's tumor. Introduction of histopathologic methodologies makes the correct diagnosis of those herpes virus-associated tumors an easy routine test.

Natural killer (NK) cells are large granular lymphocytes that play important roles in immunity against viral infection. NK cell deficiency is associated with recurrent episodes of severe herpes group virus reactivation. Few cases of NK cell deficiency have been reported. Here, we report the case of a Taiwanese girl who had suffered from severe atopic dermatitis since infancy, and recurrent episodes of herpes virus reactivation since the age of 3 years old. NK cell deficiency was diagnosed based on the finding of persistently low NK cell counts in peripheral blood. Hodgkin's lymphoma developed when she was 6 years old. The present case suggests that NK cell deficiency may be an important risk factor in the development of Hodgkin's lymphoma.

Epstein-Barr virus (EBV) is a common herpes virus linked to a variety of human neoplasms. In this study, the EBV detection was identified with the paraffin-embedded tissues from 62 non-Hodgkin's lymphomas, 20 Hodgkin's lymphomas, and 48 non-neoplastic tonsils, using PCR for EBNA-1 and EBER-1 mRNA in situ hybridization for EBER-1 mRNA. The isolates were analyzed for type 1/2, variants C/D and F/f, and LMP-1 30 bp deletion. EBV was isolated in 31 of 48 (66%) non-neoplastic tonsils, 24 of 42 (57%) B cell lymphomas, in 15 of 20 (75%) T cell lymphomas, and 17 of 20 (85%) Hodgkin's lymphomas. These viruses were classified as type 1 for 81% of non-neoplastic tonsils, 95% of B cell lymphomas, 93% of T cell lymphomas, and 73% of Hodgkin's diseases. Both type 1 and 2 viruses were isolated in one non-neoplastic tonsil and 3 Hodgkin's diseases. Type C virus was predominant in non-neoplastic tonsils (77%) and B cell lymphomas (75%), while type D virus was common in T cell lymphomas (71%) and Hodgkin's diseases (73%) (P < 0.05). Majority of the viruses detected in non-neoplastic tonsils (93%) and malignant lymphomas (91%) were "F" prototype. LMP-1 30 bp deletion was found in high frequency in both non-neoplastic tonsils (92%) and malignant lymphomas (86%). In conclusion, most of EBV found in Korea was type 1, and "DF" genotype was more frequent in T cell lymphomas and Hodgkin's diseases than in non-neoplastic tonsils and B cell lymphomas. LMP-1 30 bp deletion did not seem to be associated with malignant lymphomas.

HIV-infected patients are at an increased risk for developing cancers. Three, in particular, are considered to be AIDS-defining malignancies: Kaposi's sarcoma (KS), non-Hodgkin's lymphoma (NHL), and cervical cancer. Other non-AIDS-defining malignancies have been reported in the setting of HIV infection as having an increased frequency compared with their incidence in the general population. One of those most frequently reported is Hodgkin's disease. As with KS and NHL, the problem of diagnosing and treating immunocompromised patients with cancer represents a formidable challenge. Moreover, a newly discovered human gamma-herpes virus, human herpes virus-8 (HHV-8), has been identified in over 90% of KS lesions from patients with and without AIDS, suggesting its etiological importance in the development of KS and new therapeutic approaches.
