Tertiary syphilis may occur approximately 3 to 15 years after the initial infection and may be divided into three different forms: gummatous syphilis (15%), late neurosyphilis (6.5%), and cardiovascular syphilis (10%). [3] [25] Without treatment, a third of infected people develop tertiary disease. [25] People with tertiary syphilis are not ...
A chancre (/ ˈ ʃ æ ŋ k ər / SHANG-kər) [1] is a painless genital ulcer most commonly formed during the primary stage of syphilis. [2] This infectious lesion forms around 21 days after the initial exposure to Treponema pallidum, the gram-negative spirochaete bacterium causing syphilis, but can range from 10 to 90 days. [2]
The signs and symptoms of neurosyphilis vary with the disease stage of syphilis. The stages of syphilis are categorized as primary, secondary, latent, and tertiary. It is important to note that neurosyphilis may occur at any stage of infection. [citation needed] Meningitis is the most-common neurological presentation in early syphilis. It ...

In syphilis, the gumma is caused by a reaction to spirochaete bacteria in the tissue. It appears to be the human body's way to slow down the action of this bacteria; it is a unique immune response that develops in humans after the immune system fails to kill off syphilis. [citation needed]
Bejel, or endemic syphilis, is a chronic skin and tissue disease caused by infection by the endemicum subspecies of the spirochete Treponema pallidum. Bejel is one of the "endemic treponematoses" ( endemic infections caused by spiral-shaped bacteria called treponemes ), a group that also includes yaws and pinta .
