chancre

[shang´ker] 1. the primary lesion of syphilis, occurring at the site of entry of the infection. Called also hard, hunterian, or true chancre.2. a papular lesion occurring at the site of entry of infection in tuberculosis of the skin or in sporotrichosis.
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.

Chancre of primary syphilis. From Frazier et al., 2000.

chan·cre

(shan'ker), The primary lesion of syphilis, which begins at the site of cutaneous or mucosal infection after an interval of 10-30 days as a papule or area of infiltration, of dull red color, hard, and insensitive; the center usually becomes eroded or breaks down into an ulcer that heals slowly after 4-6 weeks. Finding Treponema pallidum on dark-field examination is diagnostic, except in oral ulcers, in which T. microdentium is normally present. Synonym(s): hard chancre, hard sore, hard ulcer, hunterian chancre, syphilitic ulcer (1) [Fr. indirectly from L. cancer]

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
