Education ulcers on the skin and mucous membranes is defined by the term chancre. The element is contagious and is a sign of genital infections. Located on the genitals and outside the genital area, develops on the internal organs. It happens hard and soft, single and multiple. All its varieties owe their appearance to bacteria. The basis of therapy is antibiotics.


Hard and soft chancra is nothing more than the point of introduction of the infectious agent into the body. Chancrats are classified by quantity, by depth of damage, localization and characterization. The number of distinguished:

  • single;
  • multiple.

Single chancres are inherent in the development of syphilis. Multiple defects are formed in a group of other venereal diseases.


On the depth of the defeat chancre are:

  • erosive;
  • ulcers.

Erosive elements are characterized by superficial tissue damage. Ulcerative deeper, purulent.

Depending on the location there are:

  • extragenital;
  • genital.

 Up to 90% of all episodes in men of chancre are localized in the genital area and anus. Recently, the tendency of defects outside the genital area has increased.

There are varieties of atypical chancre that occur on mucous membranes and other areas of the body surface.

Causes of chancre

Chancr anywhere in the body of men signals sexually transmitted infections. Its appearance is caused by bacteria of the genus Haemophilus ducreyi and Treponemapallidum. If in the first case, infections are rare, then in the second, the bacterium develops more common syphilis.


Treponemapallidum, a bacterial bacterium (pale treponema) with a spiral shape, was first discovered in 1905. The familiar theory that Treponemapallidum was imported from the Americas is being revised. Recent studies prove that the microorganism is from Africa. The reason for the entry of the pathogen into the human body is promiscuous sex. With a one-time sexual contact with a sick partner in 45% of cases of infection does not occur. With multiple connections, the risk increases. The bacterium is rarely transmitted by household, but this method is likely. Invasion is possible:

  1. When blood is infused from a person with syphilis.
  2. In contact with the health care provider and carrying out procedures.

Transplacental syphilis is another type of it. It is transmitted from the sick pregnant mother to the child and is called acquired.

The danger of the disease is that it acquires a chronic protracted form, where a person becomes a reservoir of pale treponema, being an infectious source. The incubation period is 4-5 weeks. Primary syphilis occurs for 2 months. A sign of the primary period is the formation of a hard chancre, in those places that served as a gateway for infection. The appearance of syphilitic chancre takes 10-90 days from the time of the penetration of the bacteria. After a week or two, the chancre goes away without treatment. After self-withdrawal, chancre begins a secondary period of syphilis, symptomatically characterized by a rash, general weakness, and muscle pain. After this comes the tertiary stage.

Characteristics of solid chancre

Hard chancre is similar to an ulcer and is associated with an increase in lymph nodes that swell at the site of chancre formation. Most often affected inguinal nodes. Chancre is localized on the sexual organ, but can be formed in any part of the skin and mucous membranes, which is associated not only with the sexual, but also with the domestic mode of transmission. The birth of chancre occurs in stages:

  1. First, a red spot is formed at the site of introduction of the microorganism, which does not bother the patient.
  2. In the future, after 1-2 days the stain is compacted. To the touch it will be hard.
  3. Gradually, erosion occurs at the sealing site.

The ulcer is often covered with bloom and is called chancroid. In men, the place of localization of education is the penis, the region of the head, the foreskin. Less commonly, chancre is on the pubis. With oral contact, syphiloma forms in the mouth. If an erosive element is formed in the area of ​​the anal passage, then such a chancre, unlike others, manifests itself painfully. With adequate therapy, hard chancre gradually cicatrizes.
