Question

A male presented with urethral discharge as shown in figure. What can be the cause?

• A. Gonorrhea
• B. Hemophilus Ducreii
• C. Syphilis
• D. HIV

Hint:

Think of the most common bacterial STI causing profuse purulent urethral discharge in males.

Answer 1

The Correct Option is A

Step 1: Identify the clinical features. The patient is a male presenting with urethral discharge. The image shows a white-yellowish purulent discharge from the penile meatus.

Step 2: Recall causes of urethral discharge. Common causes include gonorrhea (Neisseria gonorrhoeae), non-gonococcal urethritis (Chlamydia trachomatis), and less commonly chancroid (Haemophilus ducreyi). Syphilis causes a painless ulcer, and HIV itself does not directly produce urethral discharge.

Step 3: Match to the most likely cause. Gonorrhea produces a profuse purulent (yellow-green or white) urethral discharge, typically appearing 1-14 days after exposure. It is caused by Neisseria gonorrhoeae, a Gram-negative intracellular diplococcus. This matches the clinical picture.

Step 4: Eliminate distractors. Hemophilus ducreyi causes chancroid (painful genital ulcer with inguinal lymphadenopathy). Syphilis causes a painless indurated ulcer (chancre). HIV does not cause urethral discharge directly.

Conclusion: The correct answer is Gonorrhea.
