Rectal syphilitic ulcer.

Shyphilis is a chronic infectious disease caused by Treponema Pallidum bacteria. Syphilis is most commonly spread through sexual activity, by direct contact with the inoculation point of the spirochete. It has been demonstrated that the desease is more prevalent in men who have sex with men. In primary syphilis, the chancre appears 2-3 weeks after the initial exposure mostly in genitals, but also in oral cavity, pharynx or anus. Secondary syphilis is a systemic disease. It occurs weeks or months later in about 25% of people with primary syphilis that has not been treated. Although many people who present with secondary syphilis do not report previosly having had the classic chancre of primary syphilis.
