Simple, soft, or non-infecting chancre; a disease propagated mainly by venereal infection, and characterized by the development of a virulent ulcer (also called C. or chaneroidal ulcer) situated usually upon the genitals, and the secretion from which is contagious, but does not give rise to a constitutional affection. The lesion of c. is originally a pustule which develops immediately after inoculation, rapidly enlarges, and then breaks down, forming an ulcer with non-indurated base, discharging pus. The lymphatic glands in the vicinity often are infected, becoming swollen and painful (chancroidal bubo), and frequently suppurate. The secretion of a c. or its bubo is auto-inoculable. C. is said to be caused by Bacillus ulceris cancrosi.
