HHV-8 immunostaining may aid in the differential diagnosis with kaposi sarcoma while epithelioid hemangioendothelioma can be distinguished based on morphologic features [1]. 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 [2]. Calcineurin Inhibitors (CNIs) such as Cyclosporine and Tacrolimus are immunosuppressive agents given after solid organ transplantation, but they can also promote Tumor growth [3]. Biopsy specimens of 11 HIV-related, 7 non-HIV-related kaposi sarcoma (KS), and 7 normal skin tissues (NSTs) of Dutch origin were analyzed [4]. RNA was isolated from the paraffin material, and gene expression levels of IL-32 α, β, and γ isoforms, IL1a, IL1b, IL6, IL8, TNFA, PTGS2, CXCR1, and PTK2 were determined using real-time quantitative PCR [5].

Significantly higher expression of IL-32β and IL-32γ isoforms was observed in HIV-related KS Biopsy specimens compared with non-HIV-related KS and NST [6]. Renal transplant involvement is rare, whereas Renal transplant parenchymal involvement causing transplant dysfunction is exceptionally rare [7]. Lymphomas are perhaps the cancer type that is most closely associated with oncogenic viruses: infection with EBV, human T-lymphotropic virus 1 (HTLV-1), human Immunodeficiency virus (HIV), Kaposi sarcoma-associated herpesvirus/human herpesvirus 8, and hepatitis c virus have all been associated with lymphomagenesis [8]. Immune reconstitution inflammatory syndrome has been well described for a host of mycobacterial, viral, and fungal OIs and malignancies such as kaposi sarcoma [9]. This applies to infection-related cancers such as kaposi sarcoma, Burkitt lymphoma, Hodgkin lymphoma and hepatocellular Carcinoma, and also to two common embryonal cancers - retinoblastoma and nephroblastoma [10].

Since the discovery over 50 years ago of the Epstein-Barr virus as the cause of Burkitt lymphoma, seven other human viruses or groups of viruses-hepatitis B virus, hepatitis c virus, human immunodeficiency virus type 1, some human papillomaviruses, human T-cell lymphotropic virus type 1, Kaposi sarcoma-associated herpesvirus and Merkel cell polyomavirus-have been linked to human cancer [11]. Are co-inventors on a patent application related to the treatment of kaposi sarcoma by pomalidomide and the material in this manuscript [12].
