Malignant tumors of the ear
Malignant tumors of the ear can be both primary, i.e. developed directly in a particular department of the ear, and arising from the germination of tumors from neighboring organs and tissues. In the outer and middle ear, cancer is more often diagnosed in adults, and sarcoma in children. Of the other species, there may be melanoma. The course of tumors of the outer ear is relatively slow; they look like a granulating, bleeding ulcer or polyp. In the diagnosis of such processes, the main role belongs to the histological method.
Treatment for cancer of the outer ear can be either radiation or surgical. The choice of method depends on the morphological structure of the tumor and its prevalence. Surgical treatment options are often limited due to the proximity of the vital organs to which the tumor process passes. According to the data of V.S. Pogosov and V.F.
Therapy for sarcoma and ear melanoma is only radiation. Small melanomas of the outer ear can be removed by cryotherapy. The nearest forecast is uncertain, distant - unfavorable.
The symptomatology of malignant tumors of the middle ear is determined mainly by hearing impairment in the form of a feeling of congestion and those neurological symptoms that arise when the neoplasm spreads to the nerves, blood vessels, and brain tissue.
It should be borne in mind that the growth of a tumor in the temporal bone leads to its sequestration rather early, and the attachment of a secondary infection leads to the appearance of fetid purulent discharge. At the same time, earache and headache occur. With otoscopy, in the late stage of the process, tumor tissue, polypous masses and a large amount of pus easily bleeding when the probe is touched are determined. It is necessary to carry out a diagnosis of chronic inflammation in the ear, tuberculosis, ear syphilis, actinomycosis (it is extremely rare, more often in the external ear).
D and a gnoz are established on the basis of an otoscopic picture (easily bleeding polypoid formations), histological analysis of removed tissue pieces, results of X-ray and CT examinations (presence of extensive destruction of bone tissue).
The treatment of middle ear cancer in the early stage is combined (surgical and radiation), and in the late - radiation, chemotherapy. Sarcoma therapy involves the use of the radiation method only.
At the early stage of the disease, when the tumor did not go beyond the tympanum, it is relatively favorable. In the late period, when neighboring organs are involved in the process, it is unfavorable.

- Malignant tumors
SARCOM is a malignant tumor from the mesenchymal tissue. Unlike sarcoma cancer, the first metastases are hematogenous. Histogenesis sarcomas are divided into a number of varieties. From fibrous tissue. 1. Fibrosarcoma. 2. Swelling dermatofibroma (malignant histiocytoma) - unlike other sarcomas, it is characterized by slow growth and does not give metastasis for a long time, although it grows
- Malignant tumors
Malignant tumors of the nose and paranasal sinuses take third place in frequency among other malignant lesions of the upper respiratory tract (larynx and pharynx) and, according to published data, comprise 2 - 3% of malignant tumors of all localizations. Malignant tumors most often develop in the maxillary sinus. In second place in frequency are lattice maze tumors.
- Malignant pharyngeal tumors
The comparative incidence of pharyngeal cancers is high; carcinomas, lymphoepitheliomas, cytoblastomas, sarcomas, reticulocytomas, and mixed tumors are found among them. Men get sick more often than women, usually in middle age. K l and n and with to and to kartin and. The early symptoms of pharyngeal malignant tumors are poor and little characteristic. Light sensations may appear.
- Malignant tumors
In the upper respiratory tract, cancer is mainly found in various forms and rarely (about 3% in relation to malignant tumors of the ENT organs)
- Benign ear tumors
Ear tumors are rare diseases. There are benign and malignant neoplasms. Benign ear tumors include papillomas, fibromas, angiomas, chondromas, osteomas, etc. Of the tumor-like formations, various cysts (atheromas, dermoids, etc.) should be noted. Benign tumors are localized mainly in the outer ear.
- Malignant tumors of the nose and paranasal sinuses
Malignant diseases of this localization - cancer and isarcoma, as a rule, are primary. They are relatively rare, more often in middle-aged and elderly men. Most often, the primary malignant process affects the maxillary, then the ethmoid, frontal and sphenoid sinuses. Rarely, the nasal septum is the source of the malignant tumor. Malignancy
- Middle ear tumors
Benign tumors of the middle ear. Benign tumors include fibroma and angioma (with relatively slow growth, recurrent bleeding), endothelioma, osteoma (mastoid process), osteoblastoma of the mastoid process and pyramid. True cholesteatoma is rare in the area of the temporal bone, in the mastoid process, sometimes with spread to the tympanic
- Malignant tumors of the vulva and vagina
Vulvar cancer (RV) is found mainly in elderly women and accounts for 3-5% of all malignant diseases of the genitals. It develops against the background of involutive dystrophic processes. An important role in the occurrence of this pathology is given to metabolic and endocrine disorders and viral infection. Classification of PB by stages • Stage 0 - pre-invasive carcinoma. • I stage - tumor up to 2
- Malignant Intestinal Tumors
- these are pathological proliferation of atypical cells with an autonomous (not always) progressive irreversible nature of growth, which replace and infiltrate normal tissue. Classification of the Stage of cancer Stage 1 - a tumor of small size, localized in the thickness of the mucosa or submucosal layer, without metastases; Stage 2: a) a large tumor, but not more than a semicircle
- Malignant skin tumors
There are many theories of cancer (embryonic, virogenogenetic, hereditary, somatic mutations, etc.). Malignant tumors are characterized by infiltrating growth with destruction of the surrounding tissue and metastasis. There are two types of skin cancer: basal cell and squamous. Basal cell carcinoma, or basal cell carcinoma, occurs primarily in the elderly.
- Malignant Epithelial Tumors
They are called cancer, or carcinoma. General characteristics. 1. Meet much more often than all other malignant tumors. 2. Often associated with previous diseases and conditions, which are called precancerous. 3. The development of many carcinomas (morphogenesis) is associated with previous changes in the epithelium - hyperplasia, metaplasia, dysplasia. 4. The only precancerous
- Benign Neurogenic Tumors of the Ear
Benign neurogenic ear tumors include a glomus tumor and auditory nerve neuroma. Glomus tumor (chemodectoma, nonchromaffin paraganglioma of the middle ear or glomerulocytoma) ranks first in frequency among benign tumors of the middle ear. It develops from glomuses (glomeruli), often found formations along the tympanic nerve, ear branch
- MALIGNANT BREAST TUMORS AND PREGNANCY
Among malignant neoplasms in women, breast cancer is one of the first places. In recent years, the incidence of a combination of pregnancy and cancer has increased. There are two aspects of this problem: cancer among pregnant women and pregnancy with cancer. Breast cancer in pregnant women occurs in 0.03-0.3% of cases, pregnancy with breast cancer - in 0.78-3.8%, and in some reports
- Tumors of the outer ear
Benign tumors of the outer ear. Among the epithelial benign tumors, papilloma is often found on the skin of the external auditory canal and auricle. Treatment - excision, diathermocoagulation, cryodestruction and laser destruction. A rare tumor from the sulfur glands of ceruminoma grows slowly, with a pronounced tendency to malignancy. It is observed in people over 25 years old, similar to
