From Perplexity A.I. Make the argument that Castleman's Disease undermines the nosology, epidemiology, and virology of AIDS. Castleman disease, particularly its HIV-associated multicentric form (HIV-MCD), challenges core paradigms in AIDS medicine across nosology, epidemiology, and virology. Below is a detailed analysis of how this rare lymphoproliferative disorder complicates established frameworks. 🧬 Nosological Challenges HIV-MCD disrupts traditional AIDS classification by: Blurring diagnostic boundaries: It exhibits inflammatory symptoms (e.g., fever, cytopenia) and histopathology (plasmablastic proliferation) that overlap with—but are distinct from—classic AIDS-defining conditions like lymphoma or opportunistic infections. Dual-pathogen dynamics: Diagnosis requires confirming HHV-8 co-infection, positioning it as a viral co-pathogenesis rather than a direct HIV complication. This contrasts with AIDS nosology, which typically centers on HIV as the primary etiological agent. U...
