The ulcer begins as a painless erosion or papule that ulcerates superficially. It generally occurs alone. It has a scooped-out appearance due to level or sloping edges that are adherent, and a shining red or raw floor. The ulcer heals without leaving a scar. It may appear at almost any site including the mouth, penis, urethra, hand, toe, eyelid, conjunctiva, vagina, or cervix. Synonym: hard chancre; hunterian chancre; true chancre
