A true chancre begins as a papule which breaks down into a reddish ulcer. It is generally firm and accompanied by little or no pain. Although most frequently located on the external genitalia, it may be on the lips or fingers. In women, a chancre is sometimes concealed in the internal genitalia where it may not be seen or felt. Two or three may develop simultaneously. A chancre heals of its own accord without treatment, thus leading many persons infected with syphilis to believe they are cured. They are not, and if adequate medical treatment is not begun at this early and curable stage of syphilis, the disease will progress, doing irreparable damage.
chancreSTD The classic 1º skin lesion of syphilis, which consists of a painless 1–2 cm ulcer; the 1º chancre is highly contagious, contains zillions of spirochetes, and heals as a papule; chancres outside the vagina or on the scrotum render condoms useless in disease-preventing systems.
