Chancre is a deep dermatological lesion or ulceration essentially venereal in origin, but sometimes by extension defining other types of skin ulcerations which cause infections. The chancre is mainly located at the male or female genitalia. Sexually transmitted diseases can cause cankers like balanites in men or vulvovaginitis in women. Other conditions which are rarer today are historically associated with the presence of chancre such as syphilis
, or leprosy.
