Kaposi sarcoma, in view of its benign and chronic nature, is usually now considered to be a vascular hyperplasia rather than a true tumor. It is always linked to Human herpesvirus (HHV) 8, which is a necessary though alone insufficient condition for the development of the lesions.1 Four variants have been described: classic, endemic African, immunosuppression-associated, and human immunodeficie...

Kaposi sarcoma is an unusual tumor associated to a human herpes virus-8 infection involving the skin or internal organs. Iatrogenic Kaposi's sarcoma often occurs in patients receiving immunosuppressive therapy. So far, a few Kaposi's sarcoma cases have been reported in the literature associated with inflammatory bowel diseases. We report a 53-year-old male diagnosed with a severe refractory ulc...

BACKGROUND Human herpes virus-8 (HHV-8) is a herpes virus that is always associated with Kaposi's sarcoma. Previous studies suggested a high rate of Kaposi's sarcoma in renal transplant patients in Saudi Arabia. The aim of this study was to investigate the prevalence of HHV-8 in Saudi renal transplant recipients and healthy controls. METHODS An immunofluorescence technique was used to detect ...

skin cancer has a broad and burdensome impact on the health and well-being of iranian and account for substantial health care costs to the nation. the first most common form of skin cancer is basal cell carcinoma (bcc); followed by the squamous cell carcinoma (scc) and the incidence of malignant melanoma (mm) is lower but is fatal. kaposi sarcoma (ks) is a tumor caused by human herpes virus 8. ...

Kaposi sarcoma (KS) is a debilitating, disfiguring and often fatal disease. The tumor is always associated with Kaposi sarcoma herpesvirus (KSHV, also known as HHV8) [1]. It is often, perhaps always, associated with immune deficiency. In transplant recipients KS is associated with pharmacologic immunosuppression, while in HIV patients KS is associated with low CD4 T cell counts. Improvement in ...

Isolated pleural involvement is rare in Kaposi sarcoma (KS). We report an unusual case of bloody pleural effusion and ascites associated with KS in a kidney transplant recipient. A 50-year-old man who had received kidney transplantation from a living unrelated donor presented with a massive left-side pleural effusion, ascites, and a skin lesion. The pleural effusion and ascites were bloody. The...

Kaposi sarcoma herpesvirus (KSHV), a human gammaherpesvirus, is the etiological agent for the endothelial-derived Kaposi sarcoma (KS) and also for certain lymphoproliferative disorders. In these lymphoproliferations, the KSHV-infected cells carry the stigmata of B lymphocytes, with plasmablastic features. The JCI has published three manuscripts addressing key questions related to B cell infecti...

Kaposi sarcoma-associated herpesvirus (KSHV) is a recently discovered and characterized member of the herpesvirus family. It is one of a few viruses proved to be associated with tumorigenesis in humans. Its causal association with 4 clinical and epidemiologic variants of Kaposi sarcoma (classic, endemic, iatrogenic, and acquired immunodeficiency virus-associated) as well as with several lymphop...
