This patient presented with a penile chancre located on the proximal penile shaft, which was diagnosed as a primary syphilitic infection.
Syphilis is an infectious disease caused by the spirochete Treponema pallidum. Primary syphilitic chancres are usually firm, round, small, and painless, and develop at the spot where the T. pallidum bacteria enter the body. The chancre lasts 3 to 6 weeks, and it heals without treatment. However, if adequate treatment is not administered, the infection progresses to the secondary stage.
