Reiter syndrome associated with chlamydial infection includes urethritis, conjunctivitis, and which manifestation?

• A. Headache
• B. Rash
• C. Abdominal pain
• D. Nausea

Answer: (B)

Reiter syndrome, or reactive arthritis, usually follows a genitourinary infection such as Chlamydia. The hallmark trio is urethritis, conjunctivitis, and arthritis, but there are also non-joint features. Among these, mucocutaneous skin manifestations are common, including a rash on the hands/feet or around the genitals (keratoderma blennorrhagicum or circinate balanitis). That skin involvement is the best fit for the listed options, making rash the most appropriate answer. Headache, abdominal pain, and nausea aren’t characteristic features of this condition.
