A 36-year-old man presents with right eye watering, pain and photophobia for around 4 days. He tells you that he came back from travelling with his friends a few months ago and ‘may have’ had unprotected sex a few times. While he was away he developed an ulcer on his penis that was not painful and resolved after about 2 months. On examination, you notice a maculopapular rash on his palms and across his chest. He appears to have signs consistent with anterior uveitis on slit lamp examination. What is the most likely diagnosis?
