C46.3

Clinical Causes: Infection with Human Herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus Weakened immune system, particularly in individuals with HIV/AIDS Immunosuppressive treatments such as organ transplant medications Certain inherited immune deficiencies Other rare factors that can impair immune response

Key Symptoms: Lymphadenopathy: swollen or enlarged lymph nodes in affected regions Persistent or painless swollen lymph nodes B symptoms such as fever, night sweats, or unexplained weight loss in some cases Potential development of skin lesions or nodules if the disease progresses Fatigue or general feelings of weakness

Diagnosis Path: Medical history review and physical examination focusing on swollen lymph nodes Biopsy of affected lymph node tissue to identify characteristic tumor cells Immunohistochemistry tests to detect HHV-8 infection in tissue samples Imaging studies such as CT scans or PET scans to assess the extent of disease spread Laboratory tests including blood work to evaluate overall immune status

Treatment Protocols: Antiretroviral therapy to control HIV infection, which may help improve immune function Radiation therapy to shrink or eliminate localized tumors within the lymph nodes Chemotherapy agents aimed at controlling tumor growth and spread Immunotherapy to boost the body's own immune response against cancer cells Monitoring and supportive care to manage symptoms and improve quality of life
