Correct answer: B — Behçet disease

Recurrent oral ulcers, genital ulcers, and uveitis with a positive pathergy test in a patient from the Eastern Mediterranean 'Silk Road' region is classic for Behçet disease. This is a systemic vasculitis, not an infectious disease — the positive pathergy test (hyperreactivity to needle prick) is relatively specific. This is an important non-infectious mimic that ID clinicians must recognise. STI screening should still be performed to exclude co-existing infection.
