Basal cell epithelioma
Rodent cancer - Basalioma (basal cell epitolioma) - the most common malignant tumor of epithelium that develops from atypical basal cells of the epidermis and follicular epithelium. It is characterized by slow growth, accompanied by inflammatory infiltration and destruction of surrounding tissue and no tendency to metastasize. Similar to symptoms of squamous cell carcinoma occurs more malignant. Occurs predominantly in elderly and senile age. The most common location - the face, scalp. Appeared early in the infection a small tumor in the absence of treatment can reach considerable size, grow into the underlying tissues - muscles, bones.
Basalioma begins with the appearance of a single dense flat or hemispherical papules 2-5 mm in diameter, slightly pinkish or normal skin color. Subjective feelings are absent. Papule grows slowly and within a few years up to 1-2 cm at the same time, the central part of it falls apart and covered with bloody crust, when rejection is detected easily bleeding surface erosion or ulcer. On the periphery there is a narrow shaft, solid or composed of separate miliary nodules, slightly pinkish. Sometimes its color may be pearly or dark brown. The resulting ulcer, increasing in size, while the rumen in the central part.
Depending on the nature of growth, rodent cancer could become: a large (10 cm or more) flat plaque with a scaly surface, in much the speaker above the skin surface mushroom site, a deep ulcer that destroys underlying tissues, including bone.
The main reasons for the development of basal cell carcinoma - long-term exposure to the sun, the thermal effect of radioactive radiation, occupational hazards (exposed to arsenic, tar, tar, carbon black, dyes, oils).
Although now there are a number of effective methods of treatment of basal cell carcinoma, but none of them does not give an absolute guarantee of subsequent relapse.
Modern effective treatment - removal of basal cell carcinoma by laser or by elektronozhevogo excision. When the localization of education on the trunk and limbs, usually removed surgically. For larger its size - from 5 cm - shows the combined therapy. The complexity of tumor removal in the so-called hard to reach places, the problem areas, such as the wings of the nose, pinna, and the like, is a prerequisite for future recurrences. In addition, bazaliomnye cells can be detected at distances up to several centimeters from the lesion in the apparently healthy skin. Thus, treatment success depends mainly on the tumor, intradermal spread and depth of invasion (volumetric parameters).
