Syphilitic Chancre (Primary Syphilis)

History

           A 50-year-old man presented with an asymptomatic, rounded ulcer with hard cartilage-like sensation on palpation on the shaft of the penis just below the coronal sulcus of few weeks duration. STS (VDRL & TPHA) were positive. Two i.m.  injections of benzathine penicillin 2.4 mega units one week apart resulted in cure.
