Слайд 3: Introduction

Benign tumors are characterized by slow growth, while they are delimited from surrounding tissues and do not destroy adjacent organs. Do not germinate in the blood, lymphatic vessels, and therefore the cells of these tumors do not enter the flow of blood and lymph, not transferred to other tissues and organs. Benign tumors are not the direct cause of death of a patient, than they differ from malignant ones. With a radical removal of a benign tumor, it does not form again, and the sick woman recovers.

Слайд 5: Etiology and pathogenesis

The process of tumor transformation of cells has not yet been fully studied. It is based on damage to the genetic material of the cell (DNA), leading to disruption in the mechanisms of cell division and growth control, as well as mechanisms of apoptosis (programmed cell death). At the moment, there are a lot of factors that can cause such changes in normal cells: Chemical factors : polycyclic aromatic hydrocarbons and other chemical substances of an aromatic nature are able to react with the DNA of cells, damaging it. Physical factors : ultraviolet radiation and other types of ionizing radiation damage cellular structures (including DNA), causing tumor transformation of cells. Mechanical injuries and high temperatures with long-term exposure to the body contribute to the process of carcinogenesis. Biological factors are mainly viruses. At the moment, the leading role of the human papilloma virus in the development of cervical cancer has been proven. Disturbance of immune system function is the main cause of tumor development in patients with a decreased function of the immune system (AIDS patients). Violation of the endocrine system. A large number of tumors develops as a result of a violation of the body's hormonal balance

Слайд 6: Fibroma

Is a tumor of connective nature, often single, dense, sometimes soft formation round or oval with a smooth relief. It has a wide base or a thin stalk, not soldered to surrounding tissues. As macroscopically and microscopically distinguish between hard and soft fibroma. Fibroma is composed of cells of a mature fibrous connective tissue and collagen fiber bundles. When the loose arrangement of collagen fibers and the predominance of cell structure - soft fibroma. Thick f ibroma is characterized by a predominance of fibers with gross hyalinized and beams and a small number of cells. The most dense desmoid fibroma, which consists of interlacing bundles of connective tissue cells. Localization fibroids mainly in the interior of the labia majora or in the submucosal layer of the vagina. Fibroids are usually different slow expansive growth. Desmoid fibroma has a tendency to malignancy, while others fibroids favorable prognosis. S urgical treatment- removal is usually a brief outpatient procedure.

Слайд 7: Fibroids

swelling of the muscle fibers, often comes from tissues labia, at least - of the vaginal wall. According to the morphological structure distinguish leiomyoma - a tumor of the smooth muscle fibers and rhabdom - swelling of the cross-striped muscle fibers. Localized fibroids mainly in the interior of the labia majora, have tightly-elastic consistency. The tumor is mobile and separated from the surrounding tissue, grows slowly, favorable prognosis. Treatment is surgical.

Слайд 8: Lipoma

develops mainly of fat tissue in the pubic area and labia majora. Built of mature adipose tissue slices of various sizes, separated by irregular connective tissue layers. The tumor has a soft consistency, is surrounded by a well-defined capsule, movable with respect to the surrounding tissues, not soldered to the skin. The current benign, surgical treatment.( removal can often be done under local anaesthetic, and takes less than 30 minutes.)

Слайд 10: Myoma

Tumor from muscle fibers, often comes from the tissues of the large labia, less often - from the vaginal wall. The most common neoplasm of the uterus in women of reproductive age is 20-30% in women from 40 to 50 years - 40 % According to the morphological structure, Leiomyoma - a tumor of smooth muscle fibers and Rhabodmyoma - a tumor of transverse striated muscle fibers. It is localized more often in the thick of the labia majora, has a densely elastic consistency, mobile, unrelated to surrounding tissues

Слайд 11: Pathogenesis of myoma

in the course of repeatedly repeated cycles of myometrium hyperplasia followed by apoptosis (the dynamics of the normal menstrual cycle) there is an accumulation of smooth muscle cells with disturbed apoptosis during, these proliferating cells are exposed to various damaging factors: - ischemia (including during menstruation) - inflamed a process - a traumatic effect due to medical manipulations - the focus of endometriosis

Слайд 16: Hemangioma

occurs on the basis of a congenital malformation of the skin and blood vessels of the mucous membranes of the external genitalia and vagina. Classification: Capillary angioma is composed of a large number of capillaries intertwined with the walls of the swollen endothelium. Capillary angioma  often characterized by infiltrative growth and therefore, arisen pas vaginal mucosa, can spread to the neck, and even into the uterus. Cavernous angioma  consists of large cavities of various shapes, filled with blood, lined with endothelium. Combined hemangioma - has a subcutaneous and cutaneous parts; Mixed hemangioma - consists of different tissues.

Слайд 17: Etiological factors

Girls have hemangiomas 2-3 times more often than boys. Usually they are detected immediately after birth and much less often - during the first two months of life. The preferred location of hemangiomas is the area of ​​the head and neck. The most rare localization in the head and neck region is the parotid region. Hemangiomas can be single and multiple. A feature of hemangiomas in the perineum and external genitalia is their tendency to frequent ulceration, which leads to self-healing of the tumor. Hemangiomas is defined as bluish, purple, and red spots, a few rise above the level of the mucous membrane or skin. The mucous membrane in the swollen spots, wrinkles her raw, surface epithelium loosened. Colposcopic determined by an extensive network of anastomosing, sometimes varicose vessels. The tumor may reach large sizes and distributed on the internal genitalia.

Слайд 18: Diagnostics

Examination Laboratory diagnostics Ultrasound examination (determining the depth of the tumor and calculating the volume of education, determining the location, the structure of the tumor, measuring the speed of blood flow in the vessels). Angiography (required for examination of patients with extensive and deep hemangiomas)

Слайд 19: Treatment

Surgical treatment is indicated for deep-seated vascular hemangiomas, when it is possible to remove the entire formation, within the limits of healthy tissues, without significant cosmetic damage. Radiation treatment is subject to hemangiomas of complex locations, primarily in areas where other methods of treatment can not be used, for example, the orbit area. Radiation therapy is also indicated for simple hemangiomas of large area. Irradiation is carried out by separate fractions at intervals from 2-4 weeks to 2-6 months, until the disappearance of hemangioma. Diathermoelectrocoagulation ( moxibustion ) is subject only to small, spotted hemangiomas in those cases when the tumor is located in areas that are inaccessible to another method of treatment. Electrocoagulation of extensive and deep formations should not be used. C ryotherapy, electrocoagulation, injection of sclerosing agents

Слайд 20: Lymphangioma

develops from the lymphatic vessels of the skin most often in areas close to the groin. The tumor is multiple nodules hummocky juicy, sometimes merging with each other. Microscopically, the tumor consists of cavities of different shapes and sizes, the liquid containing the protein. The walls of the cavities are formed, and connective tissue lined with endothelium. Appearance lymphangioma is usually typical: determined bluish pale color swelling, soft, painful, sometimes slightly sensitive. To probe the dense inclusions. It grows slowly, sometimes inflamed abscesses. Treatment - surgical excision of the tumor. Forecast satisfactory.

Слайд 21: Papilloma

swelling of the surface epithelium, having the form of papillary proliferation, with exophytic growth often in the labia majora, at least - on the vaginal mucosa. Grossly papilloma limited single or multiple tumor on thin leg or on a broad basis. The surface is uneven, fine- or coarse-grained, often covered with spikes that resemble cauliflower. Different color - from white to brown. Microscopic tumor has fibroepithelial structure, sometimes with marked acanthosis. Papillomas should be differentiated from condyloma. The course mostly benign, but under certain conditions it is possible malignancy. surgical treatment of papilloma .

Слайд 22: Hidradenoma

a benign tumor o riginating from the elements of the sweat glands. Manifested mainly aged 15 to 20 years. Localization - large labia pubis. It has the kind of multiple symmetrical lesions in the form of flat, round or oval nodule size from 0.2 to 1 cm. Painting on pink-yellow to yellow-brown color. Reverse development is not exposed, not malignant. Microscopic cysts are defined in the upper part of the dermis. Cysts lined by flattened epithelial cells contain colloid mass like. Differential diagnosis with papulose syphilis. Treatment hidradenoma  surgery, a favorable prognosis.
