The majority of chancre can be found on the scrotum, and it is most common on the external genitalia, in men on the penis, prepuce, coronal groove, glans and tethered ligament, in most cases in the urethra or at the base of the penis, and in a minority of cases in the scrotum, and in women on the labia majora and minora, the cervix, and the perineum. The typical symptom of a chancre is a round or roundish ulcer, usually 1-2 cm in diameter, with clear borders and a cartilaginous hardness to the touch, which is usually painless. The surface is fleshy red. The chancre contains a large number of syphilis spirochetes and is highly contagious. The chancre usually develops as a single one, but in a few patients there can be more than one at the same time, and there is no scarring when it subsides.
