Which is not related to HIV?
Which is not related to HIV?
Show Hint
Two options are AIDS-defining opportunistic conditions; pick the one that depends only on infection duration.
Updated On: Jun 23, 2026
- Primary CNS lymphoma
- Tertiary syphilis
- Oesophageal candidiasis
- None
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Sort each option by whether it signals immune collapse from HIV. Step 2: Lymphoma of the central nervous system and candida infection of the oesophagus are opportunistic, meaning they surface only when immunity is severely suppressed - both are AIDS-defining and HIV-associated. Step 3: Late-stage syphilis, by contrast, is a slow progression of the spirochete infection itself; whether it reaches the tertiary stage is governed by how long the syphilis went untreated, not by the presence of HIV. Step 4: The odd one out, with no HIV dependence, is tertiary syphilis. \[\boxed{\text{Tertiary syphilis}}\]
