Introduction: Kaposi's sarcoma (KS) is an angioproliferative disorder first described in 1872 by Moritz Kaposi. Four main clinical presentations of KS have been described: classic, endemic, iatrogenic and epidemic. KS involvement of the lymph nodes is extremely uncommon in the classical variant form, especially if it precedes the skin manifestations. Read More

Extracellular signaling is a mechanism that higher eukaryotes have evolved to facilitate organismal homeostasis. Recent years have seen an emerging interest in the role of secreted microvesicles, termed extracellular vesicles (EV) or exosomes in this signaling network. EV contents can be modified by the cell in response to stimuli, allowing them to relay information to neighboring cells, influencing their physiology. Read More

Most chronic viruses evade T-cell and natural killer (NK) immunity through downregulation of immune surface markers. Previously we showed that Pomalidomide (Pom) increases surface expression of major histocompatibility complex class I (MHC-I) in Kaposi sarcoma-associated herpesvirus-infected latent and lytic cells and restores ICAM-1 and B7-2 in latent cells. We explored the ability of Pom to increase immune surface marker expression in cells infected by other chronic viruses, including human T-cell leukemia virus type-1 (HTLV-1), Epstein-Barr virus (EBV), human papilloma virus (HPV), Merkel cell polyoma virus (MCV), and human immunodeficiency virus type-1 (HIV-1).

Improvement of survival in lymphocytic leukaemia has been accompanied by the occurrence of second primary cancer (SPCs). Based on Swedish Family Cancer Database, we applied bi-directional analyses in which relative risks (RRs) were calculated for any SPCs in patients with chronic lymphocytic leukaemia (CLL), acute lymphoblastic leukaemia (ALL) and hairy cell leukaemia (HCL) and the risks of these leukaemias as SPCs. After CLL, RRs were significant for 20 SPCs, and high for skin squamous cell cancer (24·58 for in situ and 7·63 for invasive), Merkel cell carcinoma (14·36), Hodgkin lymphoma (7·16) and Kaposi sarcoma (6·76).

Kaposi sarcoma (KS) gained public attention as an AIDS-defining malignancy; its appearance on the skin was a highly stigmatizing sign of HIV infection during the height of the AIDS epidemic. The widespread introduction of effective antiretrovirals to control HIV by restoring immunocompetence reduced the prevalence of AIDS-related KS, although KS does occur in individuals with well-controlled HIV infection. KS also presents in individuals without HIV infection in older men (classic KS), in sub-Saharan Africa (endemic KS) and in transplant recipients (iatrogenic KS). Read More

Kaposi's sarcoma-associated herpesvirus (KSHV) is an oncogenic gamma-herpesvirus that causes AIDS-associated Kaposi sarcoma (KS) and several lymphoproliferative disorders. During the humoral immune response antigen-activated mature B cells acquire functional diversification by immunoglobulin heavy chain (IgH) class-switch recombination (CSR). CSR is initiated by activation-induced cytidine deaminase (AID) which targets highly repetitive switch (S)-regions to mediate DNA double-stranded breaks (DSBs) in the IgH locus facilitating intramolecular recombination.

Primary effusion lymphoma (pel) is a rare human herpesvirus 8 (hhv8)-related large B cell lymphoma with plasmablastic, immunoblastic, or anaplastic features that often carries a poor prognosis. This lymphoma occurs mainly in patients with hiv infection, most often with Epstein-Barr virus (ebv) co-infection, and usually presents as body cavity effusions or, less commonly, as extracavitary lesions without effusion (ec-pel). Chemotherapeutic treatment options are limited and require concurrent antiretroviral therapy (art). Read More

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and Castleman's disease. While liposomal doxorubicin has been used as an effective treatment for KS patients, the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen used for PEL patients was reported to have 1-year survival rates of less than 40%. Moreover, the development of anti-KSHV drugs inhibiting viral replication has been delayed. Read More

HIV-associated lymphomas (HALs) have high rates of latent infection by gammaherpesviruses (GHVs). We hypothesized that proteasome inhibition would induce lytic activation of GHVs and inhibit HIV infectivity via preservation of cytidine deaminase APOBEC3G, improving lymphoma control. We tested this oncolytic and antiviral strategy by using bortezomib combined with ifosfamide, carboplatin, and etoposide (ICE) alone or with rituximab (ICE/R) in relapsed/refractory HAL. Read More

KSHV is endemic in Uganda and the HIV epidemic has dramatically increased the incidence of Kaposi sarcoma (KS). To investigate the role of KSHV in the development of KS, we obtained KS biopsies from ART-naïve, HIV-positive individuals in Uganda and analyzed the tumors using RNAseq to globally characterize the KSHV transcriptome. Phylogenetic analysis of ORF75 sequences from 23 tumors revealed 6 distinct genetic clusters with KSHV strains exhibiting M, N or P alleles. Read More

High-risk human papillomavirus (HPV) infection is the etiological agent of cervical cancer and some other cancers. Kaposi sarcoma-associated herpesvirus (KSHV) represents a principal causative agent of several human cancers arising in those immunocompromised patients. In fact, KSHV DNA has been detected in the female genital tract, and this virus may share some transmission routes with HPV, although the detection rate of KSHV in cervical samples is very low and the KSHV/HPV co-infection is seldom reported.

Malignancies were one of the earliest recognized manifestations that led to the description of the acquired immune deficiency syndrome (AIDS). The majority of cancers in AIDS patients are associated with coinfection with oncogenic viruses, such as Epstein-Barr virus, human herpesvirus 8, and human papillomavirus, with resulting malignancies occurring secondary to diminished immune surveillance against viruses and virus-infected tumor cells. Over 50% of AIDS lymphomas are associated with Epstein-Barr virus (EBV) and/or HHV8 infection. Read More

Hepatic angiosarcoma and epithelioid hemangioendothelioma (EHE) might be clinically considered a spectrum since, although more frequently presenting indolent behavior, EHE occasionally evolves to high-grade neoplasms. However, in most circumstances, pathological and immunohistochemical patterns define this differential diagnosis. More recently, molecular pathways for angiosarcoma and for EHE from other organs and from soft tissue have been proved different, paving the way for future morpho-molecular assessment of their hepatic counterpart.

Kaposi's Sarcoma-associated Herpesvirus (KSHV) is the etiologic agent of several human malignancies, particularly Kaposi's Sarcoma (KS), which preferentially arise in immunocompromised patients such as HIV+ subpopulation while still lacking of effective therapeutic options. We recently found that the ribonucleotide reductase (RR) subunit M2 is potentially regulated by the key oncogenic HGF/c-MET pathway in KSHV-related lymphoma cells. One of RR inhibitor, 3-aminopyridine-2-carboxaldehyde thiosemicarbazone (3-AP) effectively induced apoptosis of KSHV+ lymphomas and suppressed tumor progression . Read More

Gastrointestinal bleeding in HIV patients secondary to coinfection by HHV8 and development of Kaposi's sarcoma (KS) is a rare complication even if no skin lesions are detected on physical examination. This article indicates which patients might develop this type of clinical sign and also tries to recall that absence of skin lesions never rules out the presence of KS, especially if gastrointestinal involvement is documented. Gastrointestinal bleeding in terms of hematemesis has rarely been reported in the literature. Read More

Introduction: Acroangiodermatitis, also known as psesudo-Kapsoi sarcoma, is a rare and benign angioproliferative malady. It presents clinically as purple-colored plaques, patches, or nodules resembling Kaposi sarcoma and is often related to chronic venous insufficiency, arteriovenous malformation of the legs, paralyzed limbs, and residual limbs. Obesity is a risk factor for venous insufficiency and could be related to acroangiodermatitis. Read More

Background: Endemic Kaposi sarcoma (KS) was first described in African children over fifty years ago, but has recently been overshadowed by HIV-related disease. We aimed to evaluate the similarities and differences between endemic HIV-negative and epidemic HIV-positive pediatric KS in a KS-associated herpesvirus-endemic region of Africa.
Methods: We describe clinical characteristics of 20 HIV-negative children with endemic KS over a six-year period and compare findings with a historical control-an HIV-related pediatric KS cohort from Lilongwe, Malawi. Read More

Noncoding RNAs have substantial effects in host-virus interactions. Circular RNAs (circRNAs) are novel single-stranded noncoding RNAs which can decoy other RNAs or RNA-binding proteins to inhibit their functions. The role of circRNAs is largely unknown in the context of Kaposi's sarcoma herpesvirus (KSHV). Read More

Background: With antiretroviral therapy (ART), AIDS-defining cancer incidence has declined and non-AIDS defining cancers are now more frequent among HIV-infected populations in high-income countries. In sub-Saharan Africa, limited epidemiological data describe cancer burden among ART users.
Methods: We used probabilistic algorithms to link cases from the population-based cancer registry with electronic medical records supporting ART delivery in the Malawi's two largest HIV cohorts, Lighthouse Trust (LT; 2007-2010) and Queen Elizabeth Central Hospital (QECH; 2000-2010). Read More

Macaque RFHV and LCV are close homologs of human KSHV and EBV, respectively. No experimental model of RFHV has been developed due to the lack of a source of culturable infectious virus. Screening of macaques at the Washington National Primate Research Center detected RFHV in saliva of SIV-infected macaques from previous vaccine studies. Read More

Primary effusion lymphoma (PEL) is a B cell lymphoma that is always associated with Kaposi's sarcoma-associated herpesvirus (KSHV) and in many cases also with Epstein-Barr virus (EBV); however, the requirement for EBV coinfection is not clear. Here, we demonstrate that adding exogenous EBV to KSHV single-positive PEL leads to increased KSHV genome maintenance and KSHV latency-associated nuclear antigen (LANA) expression. To show that EBV was necessary for naturally coinfected PEL, we nucleofected KSHV/EBV PEL cell lines with an EBV-specific CRISPR/Cas9 plasmid to delete EBV and observed a dramatic decrease in cell viability, KSHV genome copy number, and LANA expression.
