A terrible disease "Kaposi's sarcoma" was named in honor of Moritz Kaposi, Austrian dermatologist, who discovered this type of skin disease. This is a tumor that develops from cells of the blood vessels in the skin.
Kaposi's sarcoma is characterized by the appearance of spots on the skin of red-brown color, with pronounced edges. First of all, it is a malignant tumor (malignant neoplasm of the dermis), which means that it represents a threat to human life.
For the main features distinguish two forms of Kaposi's sarcoma:
- Sick disease Kaposi's sarcoma - the elderly European countries. Malignant tumor grows slowly and is located in one place, not spread to other parts of the body.
- Victims of the disease Kaposi's sarcoma are children and young people living in Central Africa. Kaposi's sarcoma, the second type of "attack" the internal organs and glands, thus often affecting the dermis. At risk are also people with AIDS.
The symptoms of Kaposi's sarcoma
Kaposi's sarcoma can affect both the skin and internal organs and lymph nodes. When the first symptoms of Kaposi's sarcoma can appear brown spot on one of the "favorite" places of the disease: in the feet, hands, lower leg. The spot is small, and only over time it can make itself felt, causing tingling and itching. Then the stain becomes brighter and begins to swell up and become the touch smooth or rough. Also available hemorrhages and pigmentation.
The development of symptoms of Kaposi's sarcoma, and can pass on to another "scenario": oval purple spots appear on the face, gradually develops and spreads to lymph nodes and internal organs, causing internal bleeding.
To distinguish three clinical stage of development of Kaposi's sarcoma:
- Spotted - the initial stage of the disease, in which just formed a diameter of 1-5mm pink spots. Surface stains even, smooth.
- Papular - still isolated from each other by elements of Kaposi's sarcoma. Continues to grow, reaching a diameter of 1 cm. At the confluence of elements formed plaques, smooth or rough to the touch.
- Tumor - formation of knots which later merge. The diameter of 5 cm.
Symptoms of Kaposi's sarcoma may not always be the same for all patients. The disease can occur in acute form, which involves rapid disease progression and death. Subacute form of Kaposi's sarcoma occurs a little slower, for 2-3 years without treatment. The chronic form of Kaposi's sarcoma is considered to be benign, so it is treatable.
Causes Kaposi's sarcoma
For a long time, scientists believed that the main cause of Kaposi's sarcoma - a special kind of herpes. But by itself it can not provoke the disease. All because of irregularities in the immune system of HIV - positive people. In such a "favorable" environment herpes virus actively multiplies, thus causing oncological diseases.
Treatment of Kaposi's sarcoma
In the process of distribution of Kaposi's sarcoma may involve other areas of the skin: the upper extremities, face, genitals. Therefore, the earlier you contact the person, the more likely it will be diagnosed and treated.
It can be applied one way to treat Kaposi's sarcoma: a topical treatment or systemic.
Local treatment of Kaposi's sarcoma involves the use of radiation and surgical techniques, cryotherapy, chemotherapy drugs injected into the tumor. It should be noted that the radiation method is applicable to all kinds / types of tumors.
Systemic treatment of Kaposi's sarcoma can be achieved only in the absence of any disturbance in the immune system. But HIV - infected are able to get systemic treatment - in this case, a systemic chemotherapy. However, the negative effect on the bone marrow kind of "therapy" does not say that this method is safe and guaranteed effective.
Prevention of Kaposi's sarcoma
Kaposi's sarcoma is in 1st place among malignant tumors of the dermis. Those at risk include:
- HIV - positive men;
- Older men older than 50 years;
- Residents of Central Africa;
Men who developed Kaposi's sarcoma, 12 times more than women.
