Which KS variant is characterized by lymph node and visceral involvement (GALT) and has poor prognosis in African children?

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

Answer: (C)

Lymphadenopathic KS is defined by prominent lymph node involvement with frequent visceral spread, including gut-associated lymphoid tissue (GALT), and it tends to have a poor prognosis in African children. This variant often presents with lymphadenopathy and abdominal symptoms rather than prominent skin lesions, and its course is more aggressive than other KS forms. In African children, the combination of lymph node involvement and visceral disease signals this specific KS variant, which carries worse outcomes. For context, classic KS typically occurs in older men of Mediterranean or eastern European descent and usually has a more indolent, skin-dominant course. Endemic KS in Africa often affects adults and may involve mucocutaneous sites with variable prognosis. AIDS-associated KS occurs in HIV-infected individuals and can be aggressive with visceral involvement, but the pattern described—lymph node-dominant disease with GALT involvement in African children—points to the lymphadenopathic form.
