[sociallocker]Correct answer is D. This patient’s clinical picture is consistent with primary syphilis. Dark field microscopy is especially useful in diagnosing primary syphilis and visualization of the spirochetes (as in this case) confirms the diagnosis. This patient’s syphilis infection suggests that he may be involved in high-risk sexual activity, also putting him at risk of HIV exposure. After proper counseling, HIV screening using ELISA should be offered.[/sociallocker]
