A previously healthy 73-year-old man presented to the urology department with marked painless ulceration of the glans penis. He denied preceding trauma and had no dysuria and no difficulty with micturition. His medical history was unremarkable apart from an episode of plasma cell balanitis 2 years prior to presentation. He was using no regular medications. A physical examination revealed striking induration of the penile shaft and purulent ulceration and destruction of the glans. He had no inguinal lymphadenopathy, and otherwise, cutaneous examination findings were normal.
