Hard chancre on the underside of the penis with the characteristic bulging edge (less pronounced here)
The ulcer durum (German: Hard chancre , outdated and Chanker ) is the primary lesion of syphilis (stage I) and usually occurs after a mean of 21 days at the site of infection (eg. The penis ) on. It is a painless ulcer in which pathogens can be detected en masse and which is therefore highly contagious. The raised, rough ( Latin durum = "hard") edge is typical . The regional lymph nodes can swell (satellite boubo), but are painless and can be moved. After about two to six weeks, this ulcer will heal with scarring. However, the infection persists and progresses to stage II disease.
Genital herpes or ulcus molle are also possible differential diagnoses .
