AIMS: Lymphoproliferative disorders (LPD) characterized by human herpesvirus 8 (HHV8) and Epstein-Barr virus (EBV) infection are rare and two entities are included in the World and Health Organization classification: primary effusion lymphoma (PEL) and germinotropic LPD. These two entities have very different clinicopathological presentations and prognosis. Here we describe two cases of HHV8-positive, EBV-positive lymphoma with clinicopathological features that are not consistent with either PEL or germinotropic LPD...

REVIEW
Kossivi Dantey, Liron Pantanowitz
Immunosuppression induced by chronic medication, such as occurs post-transplantation, may increase a patient's risk of developing solid tumors. These are often rare tumors characterized by odd presentations. This review focuses on commonly encountered iatrogenic, non-hematopoietic solid tumors following immunotherapy and provides a practical approach to their diagnosis. All of the malignancies covered in this review are viral-induced. They include human papillomavirus (HPV)-associated carcinomas, Epstein-Barr virus (EBV)-associated tumors, Merkel cell polyomavirus (MCPyV)-related Merkel cell carcinoma, and Human Herpesvirus 8 (HHV8)-related Kaposi sarcoma...

Using records from the National Cancer Data Base, we studied overall survival of CD20-negative variants of diffuse large B-cell lymphoma (DLBCL): primary effusion (PEL, N = 228), plasmablastic (PBL, N = 481), ALK-positive large B-cell (ALK + LBLC, N = 15), and human herpesvirus-8-positive DLBCL (HHV8 + DLBCL, N = 77). Three-year survival was 27% for PEL, 40% for PBL, 34% for ALK + LBCL, and 63% for HHV8 + DLBCL. Compared with unspecified DLBCL, and adjusting for clinical characteristics (including the HIV status), survival was significantly worse for PEL (hazard ratio [HR], 1...

CD20-negative diffuse large B-cell lymphomas (DLBCLs) constitute a rare and heterogeneous group of aggressive lymphomas. Known well-documented variants include plasmablastic lymphomas, primary effusion lymphomas, anaplastic kinase-positive large B-cell lymphomas, and large B-cell lymphomas arising in human herpesvirus 8 (HHV8)-associated multicentric Castleman disease. They impose diagnostic challenges for pathologists and therapeutic confrontations for clinicians. CD20 loss in B-cell lymphomas is a well-known phenomenon after rituximab therapy...

Men who have sex with men (MSM) were highly vulnerable to HIV/AIDS and Human herpes virus 8 (HHV8), while the epidemiologic features of HHV8 among MSM remain obscure. We therefore performed a systematic review and meta-analysis to assess the burden of HHV8 in MSM. Electronic databases were searched for publications on HHV8 epidemiologic characteristics among MSM. Random-effect meta-analysis was applied to combine the HHV8 seroprevalence in MSM and odds ratios (ORs) for associated risk factors. Meta-regression and stratified analyses were performed to detect the potential sources of heterogeneity...

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by overexpression of cyclin D1 resulting from t(11;14)(q13;q32) translocation. Herein, we report 3 cases of MCL with features of plasma cell-type Castleman disease (CD). The 3 patients were all men, ranging from 51 to 74 years in age, and they all presented with systemic lymphadenopathy with anemia, hypoalbuminemia, elevated serum levels of C-reactive protein, and polyclonal hypergammaglobulinemia. Lymph node biopsy specimens of the 3 cases showed histological features of plasma cell-type CD, including atrophic germinal centers and interfollicular plasmacytosis, with no light chain restriction...

Background: Non-acquired immune deficiency syndrome (AIDS) Kaposi's sarcoma (KS) is extremely rare in Japan but highly endemic in Okinawa, especially in Miyako Islands. We aimed to elucidate the exact incidence and cause of this high prevalence. Methods: Non-AIDS KS cases in Okinawa Prefecture over the past 31 years were reviewed, and human herpesvirus 8 (HHV8) seroprevalence in Miyako Islands was determined. We examined whole-genome sequences of 3 HHV8 strains and performed whole-exome sequencing of 4 male patients from Miyako Islands...

The incidence of Kaposi's sarcoma (KS) is increasing among renal transplant recipients. Patients with end-stage renal disease (ESRD) are immunocompromised and are candidates for renal transplantation, but HHV8 seroprevalence in ESRD patients has not been well documented. A cross-sectional study of 286 ESRD patients and 281 matched subjects without kidney disease was conducted at the First People's Hospital of Huzhou, Zhejiang province to explore the epidemiologic features of HHV8 among ESRD patients in China...

Human immunodeficiency virus (HIV) is well known to be associated with various neoplasms and opportunistic infections. Kaposi sarcoma (KS), associated with human herpes virus 8 (HHV8) infection, is the most common tumour in HIV positive patients and is also an acquired immune deficiency syndrome (AIDS) defining illness. Cutaneous manifestations are the most common presenting symptom; however, visceral involvement is also recognized. We present the case of a 55-year-old male who was diagnosed with AIDS-related KS, who was referred to our surgical unit with an indeterminate left adrenal lesion...

OBJECTIVE: We evaluated the subclinical shedding of six different herpesviruses in antiretroviral drug-treated HIV-positive [HIV(+)] MSM, and determined how this is associated with markers of inflammation and immune activation. METHODS: We obtained blood, semen, throat washing, urine, and stool from 15 antiretroviral-treated HIV-1-infected MSM with CD4 T-cell reconstitution, and 12 age-matched HIV-negative [HIV (-)] MSM from the Multicenter AIDS Cohort Study at four timepoints over 24 weeks to measure DNA levels of cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus 1 and 2, human herpesvirus 6 (HHV6), and HHV8...

: We describe the first case of a patient presenting Kaposi's sarcoma with human herpes virus 8 (HHV8) viremia after switching from a protease inhibitor to an integrase inhibitor-based combination antiretroviral therapy, followed by a rapid remission when resuming protease inhibitor. We suggest that the recent recommendations to switch all HIV patients to protease inhibitor-free regimens should be carefully re-evaluated especially in MSM HIV patients which are at higher risks of HHV8 infections and associated malignancies...

Post-transplant lymphoproliferative disorders (PTLD) are emergent complications of organ transplantation occurring in 2% to 10% of transplanted patients. Epstein-Barr virus (EBV) infections are considered the most important factors for the development of these heterogeneous disorders. Primary effusion lymphoma (PEL) is a lymphoproliferative disorder predominantly described in patients with advanced AIDS and it is almost universally associated with human herpesvirus 8 (HHV8). In rare case, PEL also occurs in HHV8-negative patient, in the setting of hepatitis B and C virus infection...

Iatrogenic Kaposi sarcoma (KS) has previously been reported in patients with bullous pemphigoid (BP), in relation to systemic steroids. To report three cases of previously unreported cutaneous KS during treatment with superpotent topical steroids (STS) and methotrexate (MTX). All patients were elderly men with BP treated with STS for 2 to 32 months (cumulative doses: 2,700-9,150 g) before MTX was introduced (dosage: 10-12.5 mg/week). KS occurred one to nine months after the combined therapy. In one case, KS rapidly resolved after withdrawal of MTX...

BACKGROUND: Electrochemotherapy (ECT) has shown to be an effective treatment for cutaneous and subcutaneous Kaposi sarcoma (KS) lesions. However, no study has investigated the impact of ECT treatment on the kinetics of human herpesvirus type 8 (HHV8), which is considered the necessary causal agent of KS. We aimed to evaluate HHV8 viral load and expression levels in patients affected by classic KS who received one or more ECT treatments and have been followed semi annually for up to four years...

Kaposi's disease in children with HIV is rarely reported in everyday practice. This is a case study of cutaneous Kaposi's disease revealing HIV in a 5-year-old child with polymorphic eruption of papules and nodules on the face, trunk, back, and limbs. Histopathological examination confirmed the diagnosis of Kaposi's disease. The child's HIV serology was positive with a CD4 count of 240/mm(3), normochromic and normocytic anemia, and a hemoglobin level at 8.5 g/dl. It was found that the child, after early weaning from his HIV-negative mother, had repeatedly suckled his healthy grandmother, who had no skin lesions but was HIV1 positive...

Productive viral infection often depends on the manipulation of the cytoskeleton. Herpesviruses, including rhesus monkey rhadinovirus (RRV) and its close homolog, the oncogenic human gammaherpesvirus Kaposi's sarcoma-associated herpesvirus/human herpesvirus 8 (KSHV/HHV8), exploit microtubule (MT)-based retrograde transport to deliver their genomes to the nucleus. Subsequently, during the lytic phase of the life cycle, the maturing viral particles undergo orchestrated translocation to specialized regions within the cytoplasm, leading to tegumentation, secondary envelopment, and then egress...

Primary effusion lymphoma is a rare non-Hodgkin lymphoma that presents with pleural effusions and lacking of tumour mass. It is universally associated with human herpesvirus 8 (HHV8) and is more frequent among immunosuppressed patients. There is no standard treatment, chemotherapy and anti-HIV therapy have been used with poor results, but there is still no strong evidence supporting the use of valganciclovir. We present the case of a HIV positive man that presented with pleural effusion compatible with primary effusion lymphoma and positivity for HHV8 DNA in blood...

Matthew Auten, Annette S Kim, Kyle T Bradley, Flavia G Rosado
The emergence of HIV/AIDS more than three decades ago led to an increased incidence of diseases caused by HHV8 co-infection, particularly Kaposi sarcoma, primary effusion lymphoma, and multicentric Castleman disease. Over time, the development of highly effective AIDS therapies has resulted in a decreased incidence of HHV8-associated entities, which are now more commonly found in patients with undiagnosed and/or untreated AIDS. Due to their rarity, some of these diseases may be difficult to recognize without appropriate clinical information...

After transplant, patient infection with human herpesvirus 8 (HHV-8) and Kaposi sarcoma-associated herpesvirus (KSHV) is known to cause aggressive tumors and severe nonneoplastic complications. These latter syndromes are driven by HHV-8/KSHV lytic reactivations and related hyperinflammatory host responses typically characterized by high viral loads, elevated levels of cytokines and other inflammation biomarkers, cytopenia, organ failure, high fever, and worsening conditions (with no evidence of B cell neoplasias)...
