Chancre in Syphilis

The first symptom of syphilis is a sore called a chancre (say "shanker") that is usually painless. The sore begins at the site of infection as a small, solid, raised skin sore less than 1 cm (0.4 in.) across. It develops into a red, usually painless open sore with a scooped-out appearance. The sore usually does not bleed.

Two or more chancres may develop at the same time, usually in the genital area, but sometimes on the hands, mouth, or other body surfaces.

Trichomoniasis is a sexually transmitted disease (STD) caused by a small organism called Trichomonas vaginalis. Women are most often affected by this disease, although men can become infected and pass the infection to their partners through sexual contact.

Chancres contain millions of syphilis bacteria and are highly contagious.
