This question tests whether you can separate the clinical features of secondary syphilis from those of the later, tertiary stage.
- Maculopapular rashes: seen in secondary syphilis — a widespread rash involving the palms and soles is a textbook finding of this stage, so it does not answer the question.
- Generalised nontender lymphadenopathy: also a secondary-stage finding, caused by hematogenous spread of spirochetes to lymph nodes, so it is not the answer either.
- Aortitis: this only appears in tertiary syphilis, years after infection, once endarteritis damages the aortic wall — it has no place in secondary syphilis, which makes it the correct answer.
- Follicular syphilides: the patchy alopecia of secondary syphilis, again a stage-appropriate finding and not the answer.
Correct answer: Aortitis, because it is a tertiary-stage complication, not a secondary-stage feature.
