Kaposi sarcoma is a malignant disease that originates fromthe lymphatic system. Different epidemiological, clinical andhistopathological variants of this neoplasm have been identified.Classic Kaposi sarcoma is one of the four main clinico-epidemiologicvariants. Cutaneous lesions vary from pink patches to darkviolet plaques, nodules or polyps, depending on clinical variantand stage. Kaposi sarco...

background kaposi sarcoma (ks) is an angioproliferative tumor that mainly involves mucocutaneous tissues, but extracutaneous spread to lymph nodes, gi tract, lungs, liver, pancreas, heart, and testes can occur in aids-associated ks. patients with pulmonary ks may be symptomatic or present with an asymptomatic abnormality on chest radiography. patient and method a 28-year-old man presented with ...

primary kaposi sarcoma of penis is very rare. we will introduce a 47 years old male patient referred to our clinic from dermatology service, in this report. the patient suffered from itchy penile papules around coronal region. the lab tests had revealed a negative serology of hiv but tissue pcr was positive for human herpesvirus-8 (hhv8).  histological findings were compatible with kaposi sarco...

threatening condition which is distributed worldwide. Kaposi sarcoma is the most common malignancy in AIDS patients, and cutaneous Kaposi sarcoma is frequently the initial manifestation of the disease (1). Kaposi sarcoma associated with human immunodeficiency virus (HIV) is usually widely distributed on the skin and may also be widely disseminated internally, frequently with pulmonary involveme...

BACKGROUND Despite the success of combination antiretroviral therapy (cART) in reducing the incidence of Kaposi sarcoma, HIV-infected individuals who have responded to treatment continue to be diagnosed with Kaposi sarcoma. We examine factors associated with the incidence of Kaposi sarcoma among cART-treated HIV-infected homosexual men and changes in their survival after its diagnosis over cale...

Kaposi sarcoma originates from endothelial cells and it is one of the most overt angiogenic tumors. In Sub-Saharan Africa, where HIV and the Kaposi sarcoma-associated herpesvirus (KSHV) are endemic, Kaposi sarcoma is the most common cancer overall, but model systems for disease study are insufficient. Here, we report the development of a novel mouse model of Kaposi sarcoma, where KSHV is retain...

BACKGROUND Classical Kaposi sarcoma is a rare complication of Kaposi sarcoma-associated herpes virus (KSHV) infection. We conducted a population-based, frequency-matched case-control study in Sicily to further investigate the reported inverse relationship between smoking and classical Kaposi sarcoma and to identify other factors associated with altered risk. METHODS All incident, histological...

Introduction: Kaposi sarcoma is a vascular neoplasm composed of endothelium-lined vascular spaces and spindle-shaped cells. It often manifests with multiple vascular nodules on the skin and other organs. Kaposi sarcoma is rare in HIV negative patients and it is associated with HHV-8 infection. There are four types: classic, endemic, iatrogenic and HIV-associated. Patients with HIV/AIDS are also...

Notch signaling has been implicated in the pathogenesis of Kaposi sarcoma. Kaposi sarcoma is an angioproliferative neoplasm that originates from Kaposi sarcoma-associated herpesvirus (KSHV) infection. Previously, we showed that the KSHV LANA protein can stabilize intracellular Notch in KSHV-infected tumor cells and promote cell proliferation. However, whether Notch signaling functions in pathol...
