Kaposi Sarcoma

Kaposi Sarcoma

Kaposi sarcoma is a type of cancer that develops from the cells that line lymph or blood vessels. It often appears as lesions on the skin, but it can also affect other parts of the body, including the mouth, lymph nodes, and internal organs.

Causes and Risk Factors

Kaposi sarcoma is caused by infection with human herpesvirus 8 (HHV-8), also known as Kaposi sarcoma-associated herpesvirus (KSHV). It primarily affects people with weakened immune systems, such as those with HIV/AIDS, transplant recipients, and individuals taking immunosuppressive medications.

Symptoms

Symptoms of Kaposi sarcoma depend on the location and extent of the lesions. Common signs include skin lesions (purple, red, or brown), swollen lymph nodes, and lesions in the mouth or other mucous membranes.

Diagnosis

Diagnosis of Kaposi sarcoma may involve a biopsy of the affected tissue, along with imaging tests to determine the extent of the disease.

Treatment

Treatment options for Kaposi sarcoma depend on the type and extent of the disease, as well as the patient's overall health. Options may include antiretroviral therapy (for HIV-positive patients), chemotherapy, immunotherapy, and local treatments for skin lesions.
