The course of syphilis can be characterized by the presence of the polymorphism of clinical manifestations. The rash of syphilis appears on the stage of second period, when we can speak of a spirochetal sepsis. Skin manifestations appear in the background of systemic destruction of the patient. Treatment involves only local symptoms appointment of special agents that have activity against the pathogen.
What elements need to pay attention
The first patient with syphilis rash appear after an average of six weeks after the detection of the primary lesion or chancre. Patients rash can be in several forms:
Spot pink (or roseola) appear first, while their most viewed, because they do not cause painful symptoms. The rash is not accompanied by itching, do not peel off, it does not rise above the surface of the skin intact. If you press your finger on the roseola, then it will disappear or drastically pale. Lesions in syphilis are arranged at different distances from each other and on all body parts.
During the second period of syphilis rash appears several times, but each new period of relapse can be seen that the rash is modified. The elements themselves on the skin are large, their number decreases, and they do not spread throughout the body, and are grouped together. Most of these groups of elements create intricate shapes that got the original name. The rash on the forehead gives the impression of a wreath, which has been called "the crown of Venus."
Eruptions in the form of papules joining existing roseola on the skin surface. Papular rash may appear anywhere on the body. After the disappearance of the papules on the skin is not rough scars, but only pigmented spots. The skin is often found located in the center large papules and many smaller elements around it in a circle.
The characteristics of lesions on the skin in syphilis
The appearance of all pathological elements on the skin requires a differential diagnosis for the diagnosis. Rash syphilis should be distinguished from various skin diseases. Papules, located in the palms and plantar surface, can be mistaken for psoriasis
Ringworm - not only infectious disease
, Psoriasis. There are a number of important diagnostic criteria to help distinguish the different nature of the disease. One has to resort to the serological tests to confirm the diagnosis of syphilis.
Knowledge of clinical criteria that looks like a rash with syphilis can not in practice comply with the classical ideas about the nature of the disease. We often observe the presence of several variants of the rash in different stages of development papular elements. Papules syphilis characterized by the following diagnostic features:
- clear borders
- no pain and pruritus
- the presence of infiltration of tissues
- characteristic color of ham or meat
A variety of elements on the skin or polymorphism can largely complicates diagnostic measures. In addition to the serological examination of a patient are conducting a study of cerebrospinal fluid, particularly in a period of secondary recurrent syphilis.
The rash of syphilis may appear on the background of the presence of pathological changes in the skin appendages (hair, nails). It appears a diffuse hair loss, as well as the eyelashes and eyebrows, which creates a distinctive appearance of the patient. Hair loss is often patchy, so the scalp formed small bald. This condition is typical of the second period, which occurs with recurrent disease. In this clinical situation is subject to mandatory study of cerebrospinal fluid. A favorable fact can be called that, even at the stage of secondary syphilis
Secondary syphilis - can proceed unnoticed for several years
the patient is completely cured, provided the timeliness of treatment in full.
The most severe skin lesions in syphilis
Each relapse occurs with unexpressed clinical symptoms, which is reflected in the fact that the reduced number of skin elements, and they vary in shape and size. Scanty rash does not mean that the disease is with the improvement, on the contrary, syphilis progresses, affected almost all the internal organs. Superficial skin rash gradually transformed into gross changes in the form of hillocks, which are grouped, leaving atrophic scars.
At the stage of tertiary syphilis
Tertiary syphilis - the final stage of the disease
patients will not be a characteristic rash, most often it is scarring, which is possible even after many years to recognize that a person suffered syphilis
Syphilis - punishment of Venus
. If treatment is initiated in a timely manner, then these changes can be avoided. Subcutaneous formation on the skin, in some cases resolve, but can decay with the development of the vast ulcer surface. Ulcers with syphilis do not have the correct shape and differ defeat of deep layers of the skin.
Examining the skin of the patient, should be excluded lupus, which can produce similar symptoms of syphilis. Features lupus syphilis nature of scarring on the skin. In a patient with lupus is a smooth surface scar. After an episode of relapse of the disease at the scars are formed lumps. It is considered an important diagnostic criterion, as in syphilis is not never met.
There is rarely asymptomatic forms of syphilis which do not cause pathological changes in the skin. Confirm the diagnosis allows serology. To prevent the development of complications of syphilis options in practice resorted to the study of cerebrospinal fluid. Rash, skin rash and other symptoms can not be considered specific, so only on the basis of clinical diagnosis of syphilis can not be made.
