Cutaneous manifestations of syphilis is at all stages. The elements of the skin may be of different nature, causing syphilis
Syphilis - punishment of Venus
They are often mistaken for other diseases, long, hard and unsuccessfully treated, it eventually leads to the spread of infection to the internal organs, brain and spinal cord.
Syphilis on the skin in the primary stage of the disease
The first stage of syphilis or primary syphilis is manifested most often in the form of a single element in the skin, which is called a chancre. Chancre appears on the skin at the site of the introduction of syphilis - pale treponem so often can be seen on the genitals. In men, this head and the back of the penis and the inner layer of the foreskin, at least - the skin of the scrotum and pubic area. Women chancre often located in small and large labia and clitoris, at least - in the inner thighs.
But it can also occur for the red border lips (resulting in kissing) or in any other area of skin infection in a household. But for syphilis pathogen penetrated through the skin, it should be at least a little damage: microtrauma, abrasion, wound, ulcer and so on. That is why domestic syphilis is transmitted means rare.
Chancre begins with the appearance in about 3-4 weeks (the incubation period can last from 8 days to six months) of small pink spots or papules with a solid foundation on the skin ranging in size from a few millimeters to 2 cm in diameter. Since it is absolutely painless element, it is often overlooked. After some time in the center of the papules appear, and tissue necrosis, a small painless sore round shape, smooth edges and high-solid foundation - a chancre.
Chancre most often solitary, rarely occur simultaneously 2-3 and a chancre, which are approximately the same stage of development. Rarely can watch the gradual development of multiple chancre in persons exposed to re-infection during the incubation period or within the first 10-12 days of the chancre - a so-called seronegative period of syphilis, when the blood has not yet appeared antibodies to Treponema pallidum.
After 6-7 weeks, a chancre disappears even without treatment and the disease enters the second stage - secondary syphilis.
Skin syphilis in the secondary period
Secondary syphilis begins at times not yet fully disappeared chancre. Secondary syphilis with the first period of abundant bright rash on the skin called secondary fresh. In this case, the patient's blood revealed a large number of infectious agents (pale treponem), and toxins that contribute to the appearance of rashes on the skin. At the same time the body produces enough antibodies to destroy pathogens, which leads to the disappearance of the rash and the development of the next period - secondary latent or dormant. After that, the rash appears (in the blood of many pale treponem) disappears (antibodies destroy pathogens) - a secondary recurrent syphilis. All secondary syphilis may last for 3-4 years without treatment.
Secondary syphilis manifests itself on the skin as a roseolous (in a pale pink spots), papular (a bluish or purple elevations on the skin) or pustular (in the form of pustules) rash. Thus at the open secondary syphilis rash brighter, abundant and symmetrical, while recurrent secondary syphilis - less bright and often has grouped character. Often, the skin may appear simultaneously all the elements of the rash. And as the rash is not accompanied by common symptoms, patients often do not notice at the beginning of its development.
The rash of secondary syphilis
Secondary syphilis - can proceed unnoticed for several years
it is can be confused with symptoms of other skin diseases, it may be the nature of psoriasis, acne
Acne: facial trouble
, Seborrhea, bubbly rash, warts wide (they need to be distinguished from genital warts viral origin), located just on the palms and soles, and so on.
All rashes secondary period of syphilis disappear, usually without a trace and without treatment in 3-4 years, the disease becomes Tertiary period.
The manifestation of syphilis on the skin in the Tertiary period
Tertiary period is characterized by the fact that the blood is very pale treponem content decreases and thus there is a sharp increase in the sensitivity of the patient to them (sensitization).
Skin rash with tertiary syphilis
Tertiary syphilis - the final stage of the disease
are bumps and Gunma formed as a result of allergic reactions to tissue necrosis, so they always leave behind scars.
The bumps - it is small (0, 3 and 1 cm in diameter) clear dense rounded education reddish-bluish color, located in the skin and are prone to bundling. In the center of these bumps necrosis begins, after which the skin initially formed small sores and scarring later.
Gunma - education is up to 1, 5 cm in diameter, located in the deep layers of the skin and subcutaneous tissue. Gunma more often single, they also settled in the form of necrosis, followed by the formation of nonhealing ulcers and large scars.
Distinguish cutaneous manifestations of syphilis from the symptoms of other skin diseases can only be a specialist.
