Which KS type has no association with HIV?

Which KS type has no association with HIV?

• A. AIDS-associated KS
• B. Classic KS
• C. Endemic KS
• D. Transplant-associated KS

Answer: (D)

Kaposi sarcoma arises when HHV-8–infected endothelial cells proliferate in the setting of immunosuppression. The HIV connection specifically drives the AIDS-associated form, where HIV-induced immune deficiency allows KS to emerge. While classic KS and endemic KS can occur without HIV, transplant-associated KS is driven by iatrogenic immunosuppression from anti-rejection drugs after organ transplantation rather than by HIV infection. That makes transplant-associated KS the type not associated with HIV in terms of the underlying trigger, even though HIV-positive individuals can still develop KS in other contexts.
