Syphilis is a sexually transmitted infection that commonly starts with a painless sore called a chancre.
A rare case of syphilitic balanitis was reported in a 26-year-old male who had asymptomatic red plaques on the glans and prepuce after unprotected sex.
This unusual presentation is seen in only 0.3%-0.5% of primary syphilis cases, making it a noteworthy find in medical literature.
