Skin tumors

To benign tumors include a hemangioma (see), lymphangioma (see), fiber (see), a lipoma (see). The surgical treatment; if the hemangioma is sometimes used radiation therapy. Malignant tumours include cancer, sarcoma, melanoma (see).
Cancer of the skin is most often occurs on the face and back surfaces of hands, less often on the trunk, men often localized on the skin of the scrotum. In the occurrence of skin cancer can be important external factors, the long-term and re-active (professional and home): chemical, thermal, radiation (radioactive substances), solar light, cooling and other skin Cancer develops either on an unmodified skin or on the background of previous precancerous diseases or long-existing pathological changes (for example, tuberculosis skin). Precancerous changes transform into cancer not in all cases (optional the precancer). These changes include: cutaneous horn (see), Karatau senile (see), a leukoplakia (see), psoriasis (see), radiation dermatitis and radiation ulcers (see Radiation damage), chronic ulcers, scars after burns, fistulas when osteomyelitis and the paraproctitis , etc. In all cases, degenerate into malignant neoplasms (obligatory precancer) pigmentosum pigment (see), Voenna disease (see).

There are squamous cell carcinoma of the skin (the initial form of his first called epitheliomas) without keratinization and keratinization. Squamous cell carcinoma without keratinization looks flat ulcers with a dry light-bottom and thick bright valikoobraznye edge (Fig. 2). The growth of tumors initially slow, over time becomes aggressive nature of the tumor infiltrates underlying tissues until the bones of the skeleton and gives metastases in regional lymphatic nodes. Squamous cell carcinoma with keratinization looks exophytic tumors and also infiltrates the underlying tissues.
Other malignant tumors: fibrosarcoma, having a form platinovogo yellow-brown node, sarcoma Kaposi as first single, and then multiple red-brown plaques and tangles, angiosarcoma, retikulosarkoma primary and multiple secondary. There are specific and non-specific skin lesions with chlamydia (see).

To common skin tumors is basal cell carcinoma (see).
The diagnosis of tumors of the skin is fairly easy; skin cancer can be installed by a specialist clinically. Confirmed diagnosis is microscopic examination of fingerprints or separable from the surface ulcers or biopsy (see) from the edges of the ulcer (but not suspected melanoma).
The treatment is carried out by specialists. Use of surgical or radiation treatment (if necessary). Timely and correct treatment of skin cancer is effective in 95% of cases.
Prevention: strict observance of personal hygiene when working with hazardous substances (aniline dyes, petrol, tar and other). Working in hazardous industries necessary protective clothing; they should be kept under systematic medical supervision. Chronic skin diseases patients should be sent for consultation to the oncologist.
