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.
[Fr. indirectly from L. cancer]

hard chancre

Etymology: AS, heard + Fr, canker
a syphilitic chancre or primary lesion that develops at the site of a syphilis infection. The lesion begins as a small red papule that gradually hardens and erodes into an extremely contagious, although painless, ulcer. A secretion exuded by the sore contains Treponema pallidum, the organism that is the causative agent of syphilis in humans.

TYPICAL CHANCRE OF PRIMARY SYPHILIS
A hard, syphilitic primary ulcer, the first sign of syphilis, appearing approx. 2 to 3 weeks after infection. See: illustration; syphilischancrous (shang'krus), adjective

Symptoms

The ulcer begins as a painless erosion or papule that ulcerates superficially. It generally occurs alone. It has a scooped-out appearance due to level or sloping edges that are adherent, and a shining red or raw floor. The ulcer heals without leaving a scar. 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

CAUTION!

During the chancre stage, syphilis is highly contagious. The chancre contains many spirochetes.
