    Kaposi’s sarcoma (KS) is an angioproliferative tumour that requires infection by Human Herpesvirus 8 (HHV-8). It most commonly affects elderly men of Mediterranean/Eastern European backgrounds and HIV-infected patients. KS presents clinically as lesions on the skin, but may also arise in the gastrointestinal tract, lungs, and lymph nodes. There is no definitive cure for KS; therapeutic goals are to decrease the size of the lesions, prevent progression and improve function. Management depends on the type of KS, extent of disease and overall health of the patient. Observation is acceptable if the patient is asymptomatic; HAART is often sufficient to control lesions in HIV-infected patients. Cryotherapy and local excision can be used to treat solitary symptomatic lesions. Radiation therapy can be used for advanced and extended KS and in those patients for whom surgery is contraindicated. Intra-lesional injection of interferon alpha-2a or chemotherapeutic agents like vincristine have been reported to be effective in treating nodular KS lesions, but may be associated with inflammation and discomfort. Systemic chemotherapy such as pegylated liposomal doxorubicin is indicated when KS is widespread or rapidly progressive. The prognosis for KS is generally great with most patients dying from unrelated causes.
