Sarcoidosis of the skin - is the second most common form of this systemic disease.Sarcoidosis can affect a variety of organs and body systems.Simultaneously, the skin may be affected lymph nodes Lymph nodes - what keeps our immune system , lungs, liver, spleen, nervous system and even the heart.Therefore, detection of skin sarcoidosis patient should be fully examined.
Cutaneous sarcoidosis - why he begins
why skin begins sarcoidosis is unknown.Previously, this disease was considered a form of tuberculosis.Today, it is known that tuberculosis is not related, but Tuberculosis Tuberculosis - a full recovery is not guaranteed could join him.
main cause of sarcoidosis (including sarcoidosis skin) modern researchers believe hereditary characteristics immunity Immunity - the types and characteristics of children in adult - its ability to respond in a certain way to certain effects.Thus, in order to sarcoidosis emerged Sarcoidosis - how to protect themselves? , needed for several reasons.On participation in its development of hereditary factors suggest familial forms of the disease.
skin sarcoidosis affected every third or sixth patient.
This woman sarcoidosis of the skin (and all other forms of sarcoidosis) get sick more often than men.The disease develops mostly in the age of 20-40 years.
What are the symptoms of sarcoidosis skin
characteristic manifestation of sarcoidosis are inflammatory lung nodules - granulomas.Cutaneous sarcoidosis granulomas are located in the middle and deep layers of the skin and called sarcoidosis Beck - on behalf of the Norwegian dermatologist who first described them in the late 19th century.
Ts.Bek described three types of sarcoids - scattered melkouzelkovye rashes and krupnouzlovaty and diffuse infiltrative appearance sarcoids.Today it is known as other cutaneous manifestations of sarcoidosis: Chilblains lupus Besnier-Tennesona, angiolyupoid Brock Potro and subcutaneous sarcoid Darya-Roussy.
cutaneous manifestations of sarcoidosis are combined with the involvement of other tissues and organs, but there are also isolated.Disease often begins gradually: first appear on the skin sarcoid isolated, but gradually their number increased.
Melkouzelkovy sarcoid looks like a well-circumscribed reddish to bluish tint or brick red nodules the size of 5-6 mm.The surface is smooth nodules, sometimes it is a little flaky.Plotnovata nodules or hard to the touch, painless, located on the face, upper torso (a cape) and the extensor surfaces of hands.
nodules are from several tens to hundreds of thousands in the process may be involved the entire surface of the body except the palms and soles.
Over time, the nodules are flattened in their place are small dark spots or skin atrophy (decrease in volume) surrounded by pigmented rim.Eruptions appear episodic, between attacks may take place months or years.
Krupnouzelkovy sarcoid - a single (their is no more than a dozen) protruding above the skin nodules larger than melkouzelkovye elements (they can reach 1-2 cm in diameter), brownish or reddish-bluish color.Sarcoid located mainly in the face and neck, less - on hand in the groin area and lower extremities.On the surface there are whitehead (whiteheads, resulting from the increased activity of the sebaceous glands) and telangiectasia (persistent dilation of small blood vessels, visible as a red spot on the skin).
sarcoid skin over smooth or slightly scaly, with its probing the pain is not detected.Krupnouzelkovye arkoidy may remain unchanged for years, but may be subject to reciprocal and development.In this case, in their place are brown or white spots surrounded by towering ring brownish skin.During exacerbation of these rings often appear melkouzelkovye sarcoid.
krupnouzelkovy sometimes takes the form of single sarcoid patches of soft consistency with a lot of telangiectasia.Such elements are called Broca angiolyupoida Potro.Eruptions are placed on the forehead, the side surfaces of the upper part of the nose, are bluish color with a brownish tint.
Diffuse-infiltrative form of cutaneous sarcoidosis is not as common and is characterized by the formation of mild delineated infiltrative lesions rather compact texture, reddish-bluish color, with a diameter of 10-15 cm and more.
When perfrigeration lupus Besnier-Tennesona on the skin of the cheeks, nose, ears, chin and forehead appear clearly demarcated from healthy tissue red-purple flat or slightly convex without peeling lesions and atrophy, which leaves no scarring.
More rarely seen subcutaneous sarcoid Darier-Roussy - subcutaneous nodules as small as a walnut, dense, painless, prone to mergers and the formation of large infiltrations.Located such nodes on the sides of the torso, abdomen and thighs.
sarcoidosis skin held glucocorticoid hormones that are assigned, both internally and externally, in the form of ointments and creams.Treatment long, it may take several months.
