Figure Legend:
This image shows an extensive chancre located on the penile shaft due to a primary syphilitic infection caused by Treponema pallidum. The primary stage of syphilis is usually marked by the appearance of a single lesion called a chancre. The chancre is usually firm, round, small, and painless. It appears at the spot where T pallidum entered the body, and lasts 3 to 6 weeks, healing on its own. Courtesy of Centers for Disease Control and Prevention
