Which KS variant is prevalent in Bantu children of central Africa and tends to involve lymph nodes and viscera with a poor prognosis?

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

Answer: (A)

In Kaposi sarcoma, the way the disease presents varies by geography and patient population. In sub-Saharan Africa, especially among Bantu children, KS often shows up as a lymphadenopathic form, where lymph nodes are the main site affected and visceral (internal organ) involvement is common. This pattern marks a more aggressive disease course and carries a poorer prognosis compared with other KS variants. Classic KS tends to present mainly with indolent skin lesions in older Mediterranean populations, and AIDS-associated KS can involve the skin and mucous membranes in HIV-infected individuals but with different epidemiology. The description given—prevalent in Bantu children of central Africa with lymph node and visceral involvement and a poor prognosis—fits the lymphadenopathic form, making it the best match for this scenario.
