Case in brief

A 54-year-old heterosexual male presented with a solitary, indurated ulcer on the mons pubis, following minimal trauma from shaving three weeks prior. Initial treatment for bacterial folliculitis led to worsening of the lesion. Diagnosis of a chancre was confirmed through polymerase chain reaction (PCR) for Treponema pallidum and syphilis serology.

Diagnostic / clinical pearl

Syphilis should be considered in the differential diagnosis of any anogenital ulceration, even in atypical locations and populations.
