Which tumor is described as a malignant connective tissue tumor commonly associated with HIV/AIDS?

• A. Lymphoma
• B. Kaposi sarcoma
• C. METs
• D. Hepatoblastoma

Answer: (B)

Kaposi sarcoma is a malignant tumor of endothelial (vascular/mesenchymal) origin, classically described as a malignant connective tissue tumor that is strongly associated with HIV/AIDS. This link to immune suppression makes it the prototypical example of an AIDS-related malignant vascular neoplasm. In the abdomen, it can involve the liver, spleen, or lymph nodes and may present as nodular or mass-like lesions on imaging, though skin lesions are most characteristic. The other options don’t fit this description: lymphoma is a malignant lymphoid tumor, metastatic disease refers to spread from another primary, and hepatoblastoma is a pediatric liver tumor not tied to HIV/AIDS.
