Kaposi's sarcoma is commonly associated with which condition?

• A. Hypertension
• B. Diabetes mellitus
• C. Human immunodeficiency virus
• D. Asthma

Answer: (C)

Kaposi's sarcoma is a vascular tumor that occurs most often when the immune system is compromised, especially in people with HIV infection. In advanced HIV/AIDS, it frequently presents as purplish skin lesions and can involve the oral mucosa, driven by infection with human herpesvirus 8 (HHV-8). This association with HIV reflects a state of immunosuppression that allows the angioproliferative growth to develop. Hypertension, diabetes mellitus, and asthma do not have this link to Kaposi's sarcoma, whereas HIV infection is the key connection in this context. In dental care, awareness of possible oral Kaposi's sarcoma in patients with HIV is important, as it requires medical evaluation and management.
